What are the three parts of the brain and what parts the brain is divided into

The three-part structure that makes up the brain is the cerebrum, cerebellum, and brainstem.

The brain is a major part of the central nervous system and is located in the cranial cavity. The brains of lower vertebrates are simpler. The brains of humans and mammals are particularly well developed.

The brain includes telencephalon, diencephalon, cerebellum, and brainstem. The brainstem includes the midbrain, pons, and medulla oblongata. There are many nerve nuclei or nerve centers concentrated by nerve cells, and a large number of upper and lower nerve fiber bundles pass through it, connecting the brain, cerebellum and spinal cord, and linking all parts of the central nervous system into a whole in terms of morphology and function.

The spaces in the parts of the brain are called ventricles and are filled with cerebrospinal fluid.

The brain, cerebellum, brainstem, brain, and spinal cord are collectively referred to as the central nervous system, and the brain is the main part of the central nervous system, located within the cranial cavity. The brains of lower vertebrates are simpler. The human and mammalian brains are particularly well developed and can be divided into three parts: the brain, the cerebellum, and the brainstem.

The brain includes teleencephal, diencephalon, midbrain, pons and medulla oblongata, and is home to many nuclei or nerve centers formed by the concentration of nerve cells.

The brain is the main part of the central nervous system and is located in the cranial cavity. The human and mammalian brains are particularly well developed and can be divided into three parts: the brain, the cerebellum, and the brainstem. The brain includes teleencephalitis, diencephalon, midbrain, pons and medulla, and there are many nuclei and nerve centers concentrated by nerve cells, and a large number of ascending and descending nerve fiber bundles pass through to connect the brain, cerebellum and spinal cord, and connect all parts of the central nervous system as a whole in morphology and function.

The left brain controls the right side of the body, the right brain controls the left side of the body, the cerebellum controls the endocrine and nervous systems, the brain processes information, and the cerebral cortex is responsible for memory functions.

Central nervous system.

The main part is located in the cranial cavity. The brains of lower vertebrates are simpler. The human and mammalian brains are particularly well developed and can be divided into three parts: the brain, the cerebellum, and the brainstem.

1) Brain: It is the highest part of the nervous system, which is composed of two cerebral hemispheres, the left and the right, and there are horizontal nerve fibers between the two hemispheres. Each hemisphere includes:

Cerebral cortex (cerebral cortex): is a layer of gray matter (the concentrated part of the cell body of nerve cells) on the surfaceThe surface of the human brain has many concave sulcus (fissures) with a raised gyrus between the sulcus (fissures), thus greatly increasing the area of the cerebral cortex.

The human cerebral cortex is the most developed, it is the organ of thinking, which dominates all the activities in the body and regulates the balance between the body and the surrounding environment, so the cerebral cortex is the material basis for high-level neural activities. Medulla: Also known as:"White matter, located inside the cerebral cortex, is made up of nerve fibers.

Basal ganglia: In the white matter at the base of the hemisphere, it is formed by the concentration of nerve cells.

2) Cerebellum: In the posterior and lower part of the brain, it is divided into the vermican in the middle and the enlarged cerebellar hemispheres on both sides, and the gray matter on the surface is the cerebellar cortex, which is divided into many lobules by many transverse grooves. The inner part of the cerebellum is made up of white matter, called the medulla, which contains nerve fibers associated with the brain and spinal cord.

The main function of the cerebellum is to coordinate the movement of the skeletal muscles, maintain and regulate the tension of the muscles, and maintain the balance of the body.

3) Brainstem: including diencephalon, midbrain.

The pons and medulla oblongata are home to many nuclei or nerve centers that are concentrated by nerve cells.

A large number of ascending and descending nerve fiber bundles pass through and connect the brain, cerebellum and spinal cord, linking the central nervous system into a whole morphologically and functionally. The spaces in each part of the brain are called the ventricles.

Filled with cerebrospinal fluid. In the human body, the brain is usually divided into four parts: the cerebrum, cerebellum, diencephalon and brainstem (including the midbrain, pons and medulla oblongata).

The brain is made up mainly of the body's nerve cells.

The edges of each nerve cell have a number of outward protruding parts, called dendrites and axons.

The human brain is the main component of the human body, and it helps people remember everything. At the end of the axon there is a bulging protrusion called a synapse.

Bodies. The synaptosomes of each neuron are in contact with the dendrites or axons of another neuron. This structure is called a synapse.

Neurons communicate with other neurons through "synapses" and receive information from many other neurons. How many synapses are there on each neuron? It has been estimated that in people the cerebral cortex.

There are an average of 30,000 synapses on each neuron. So, how many neurons does the human brain have? There are about 14 billion of them. The synaptic connections between these 14 billion nerve cells are also difficult to express in astronomical numbers.

The function of neurons to transmit and receive information is the physiological basis of the brain for memory. It is this structure that allows the brain to form a huge reservoir of information, and scientists believe that the human brain stores information equivalent to the content of a billion books. It can be seen that our brains have an infinite memory capacity.

It's really hard to imagine what a person without memories would be like? We know that memory is everywhere and all the time in people's lives. It is with these thinking and memory abilities that human beings are able to learn.

The brain is located in the cranial cavity, including the brain, cerebellum and brainstem, the brain is composed of two cerebral hemispheres, the surface layer of the cerebral hemisphere is gray matter, called the cerebral cortex, the cerebral cortex is the highest center that regulates human physiological activities; The cerebellum is located on the dorsal side of the brainstem, the lower back of the brain, and the main function of the cerebellum is to coordinate and accurately exercise and maintain the balance of the body; The brainstem is located at the bottom of the brain and the front of the cerebellum, and its lowest part is connected to the spinal cord, and the gray matter of the brainstem contains some centers that regulate the basic life activities of the human body (such as cardiovascular center, respiratory center, etc.).

The brain is divided into four parts: telencephalon (brain), diencephalon, cerebellum, and brainstem; The brainstem includes the midbrain, pons, and medulla oblongata. The brain is a major part of the central nervous system and is located in the cranial cavity. The brains of lower vertebrates are simpler. The human and mammalian brains are particularly well developed.

The higher part of the central nervous system of cerebral vertebrates, the main regulator of vital functions. Among them, the human brain is the most complex and extremely functional substance. It is the organ of the mind, the material ontology of the mind and consciousness.

There are many nerve nuclei or nerve centers concentrated by Li Shu nerve cells, and a large number of ascending and descending Li pants nerve fiber bundles pass through to connect the brain, cerebellum and spinal cord, and connect all parts of the central nervous system as a whole in terms of morphology and function. The spaces in the parts of the brain are called ventricles and are filled with cerebrospinal fluid.

The human brain is a complex organ, which is mainly composed of three components: the brainstem, the cerebellum and the brain. Each part has its own function and physiological structure.

Brainstem: Located between the brain and spinal cord, the brainstem is an important hidden passage that connects the brain to the rest of the body. The brainstem controls many basic vital functions, such as breathing, heartbeat, and blood pressure. It also regulates physiological processes such as sleep, wakefulness, and digestion.

Cerebellum: The cerebellum is located underneath the brain, and it makes up about 10% of the brain's weight. The cerebellum is mainly responsible for coordinating and regulating movements, making the body's movements more coordinated and fine. It is also related to aspects such as balance control and spatial orientation.

Brain: The brain is the center of human thinking, memory, learning, perception, and control of movement. The brain is made up of two hemispheres that control the left and right parts of the body.

The cortex of the brain is the outermost layer of the brain, which is the higher functional area of the brain and is responsible for aspects such as language, thinking, perception, memory, and decision-making.

Composition of the brain. The brain structure mainly includes teleencephal, diencephalon, cerebellum, midbrain, pons, and medulla oblongata.

The human brain is developed from the anterior division of the neural tube during the embryonic period, and is the highest part of the central nervous system. It is usually composed of 6 parts, including telencephalon, diencephalon, cerebellum, midbrain, pons and medulla oblongata.

1.The medulla, pons, and midbrain make up the brainstem, which is similar to the spinal cord and is composed of gray matter, white matter, and reticular structures, which is more complex than the spinal cord. It contains a variety of motor and sensory nuclei, such as general somatic motor nuclei and special visceral motor nuclei, which govern the movement of muscles and internal organs of the human body.

2.The cerebellum is one of the important somatic motor regulation centers of the body, and its functions are mainly to maintain body balance, regulate muscle tone, and coordinate voluntary movements.

3.The diencephalon, located between the midbrain and telencephalon, connects the cerebral hemispheres to the midbrain.

4.The telencephalon is composed of the left and right cerebral hemispheres and the interhemispheric commissure and its internal cavity, including the occipital, parietal, temporal, frontal and other regions, which control the active functions of the human body such as listening, speaking, reading and writing.

Each hemisphere has a cavity inside the hemisphere, called the lateral ventricle, which is filled with cerebral effusion.

The cerebellum includes the left and right hemispheres and the upper and lower primers in the middle, and the upper, middle, and lower feet are connected to the brainstem. The diencephalon is located in the brain, between the two hemispheres. Its lateral surface is connected laterally to the lateral area between the two hemispheres of the brain.

It consists of a deep, narrow, vertical median fissure called the third ventricle. The brainstem is composed of the midbrain, pons, and medulla oblongata, and is connected to each other. The back connects the cerebellum, the cephalad connects the diencephalic end, the caudal end connects with the spinal cord, and there is a fourth ventricle between the brainstem and the cerebellum.

The main components of the brain are as follows:

1. Brain: including frontal, temporal, parietal, occipital and insula;

The frontal lobe is associated with spiritual, linguistic, and voluntary movements;

The parietal lobe can distinguish higher senses; The functions of the temporal lobe include language comprehension, hearing, mental activity, memory, smell, etc.;

The occipital lobe is responsible for processing visual information as the visual cortex center, which can be transmitted from the retinal photoreceptor to the occipital lobe optic center of the brain to process visual information.

The insula lobe is mainly related to visceral sensation and movement; The limbic lobe is involved in higher nervous, mental, emotional, memory, visceral activities.

3. Cerebellum: including cerebellar hemispheres and cerebellar seclusion, which is mainly related to balance and fine motor skills;

5. Other components: such as cerebrovascular, ventricles, deep white matter of the brain and related nuclei, such components form a complex network with the gray matter of the brain, cerebellum and brainstem, which play a vital role in learning, memory, cognition and limb function.

The brain is the most important central nervous system of the human body, which controls the sensations and movements of the body, and also directly controls the consciousness of thinking, emotion, memory, etc.

It is composed of three parts: brainstem, diencephalon and cerebellum.

1. Brainstem: including medulla, pons and midbrain. The medulla oblongata is located above the spinal cord and the cerebellum is located dorsally.

Function: Control breathing, excretion, swallowing, gastrointestinal and other activities. The pons, located above the medulla oblongata, is the only way to transmit information between the central and peripheral nerves to regulate and control sleep.

The midbrain is located at the base of the thalamus, between the cerebellum and the pons.

2. Diencephalon: All the input information from the external sensory organs of the thalamus is directed to the cerebral cortex through the thalamus, thus producing vision, hearing, touch and taste, and it is important to control sleep and wakefulness. The hypothalamus regulates autonomic nerves, which is important for maintaining internal homeostasis and controlling the activity of endocrine glands.

3. Cerebellum: There is cerebellar cortex and medulla.

1. The human brain is composed of the brain, the small pin brain, the diencephalon and the brainstem.

2. The brainstem is connected to the cerebral hemisphere and the spinal cord below, and is irregular columnar. Nerve impulses that pass through the spinal cord to the brain enter in a crossover pattern: impulses from the right side of the spinal cord first travel to the left side of the brainstem and then to the brain; Those who come from the left side of the spinal cord are first sent to the right side of the brainstem, and then the bad news is transmitted to the brain.

The function of the brainstem is mainly to maintain the life of an individual, including important physiological functions such as heartbeat, breathing, digestion, body temperature, and sleep, which are all related to the function of the brainstem.

3. The cerebellum is located below the brain and occipital lobe, just behind the brainstem, and is the second largest part of the brain. The cerebellum is made up of two hemispheres, the left and right hemispheres, with gray matter on the outside and white matter on the inside. Functionally, cerebellar and cerebral cortex exercise together to control muscle movement in order to regulate posture and body balance.

4. The forebrain belongs to the highest part of the brain and is the most complex and important nerve center in the human brain. The forebrain is divided into four parts: the optic thalamus, the hypothalamus, the limbic system, and the cerebral cortex.
