What does the human nervous system consist of? What does the nervous system consist of?

It is divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord, and the peripheral nervous system includes cranial nerves and spinal nerves.

1. Central nervous system.

The central nervous system is made up of the brain and spinal cord, which are the central part of various reflex arcs, and are the most dominant parts of the human nervous system.

The central nervous system receives incoming information from all over the body, which is integrated and processed into coordinated motor efferents, or stored in the central nervous system as the neural basis for learning and memory. The activity of the human mind is also a function of the central nervous system.

2. Peripheral nervous system.

It is composed of nerve trunks, plexus, ganglia, and nerve terminal devices composed of perinuclear bodies and nerve fibers. Anatomically, it is often divided into three parts: cranial nerves, spinal nerves, and autonomic nerves. Its function is to connect peripheral receptors to the central nervous system.

The activity of various organ systems in the human body.

The nervous system consists of three parts: central nervous system, peripheral nerve, and splanchnic nerve. 1.The central nervous system is made up of the brain and spinal cord.

The cerebrum includes the cerebrum, diencephalon, cerebellum, and brainstem (divided into midbrain, pons, and medulla); The spinal cord has 31 segments. That is, 8 cervical segments, 12 thoracic segments, 5 lumbar segments, 5 sacral segments, and 1 caudal segment. 2.

Peripheral nerves are made up of cranial and spinal nerves. Among them, there are 12 pairs of cranial nerves and 31 pairs of spinal nerves. 3.

Splanchnic nerves are made up of afferent (sensory) fibers and efferent (motor) fibers. Efferent fibers are divided into sympathetic and parasympathetic nerves.

The basic structural unit of the nervous system is neurons, which are composed of two parts: the central nervous system and the peripheral nervous system. The former includes the brain and spinal cord, and the latter includes the cranial nerves and spinal nerves.

The central nervous system is composed of the midbrain: cerebrum, cerebellum, and brainstem. The left side of the brain controls the right side of the body and is responsible for language and logical thinking. The right side of the brain controls the left side of the body and is responsible for artistic thinking.

The cerebellum maintains body balance and makes movements coordinated accurately; The brainstem manages the functions of a person's respiratory and circulatory systems. The spinal cord, located in the spinal canal, has functional reflexes and conduction functions. In the central nervous system, a large number of nerve cells are clustered together to organically form a network or circuit; Its main function is to transmit, store and process information, produce various psychological activities, dominate and control all animal behaviors, mainly enable people to carry out normal daily activities, as well as the movement of hand and foot functions, as well as allow people to carry out normal language, thinking communication and creation and other functions.

The peripheral nervous system consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves emanating from the spinal cord. Cranial nerves are mainly distributed in the sensory organs, muscles and limbs of the head and face. In addition, there are 31 pairs of nerves from the spinal cord, including 8 pairs of cervical nerves, 12 pairs of thoracic nerves, 5 pairs of lumbar nerves, sacral nerves, and 1 pair of caudal nerves.

Hello, the nervous system is mainly divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system in turn includes the brain and spinal cord, and the peripheral nervous system includes nerves and spinal nerves.

The nervous system is a large range, which is mainly used to control the regulation of physiological activities, mainly divided into two parts, that is, the peripheral nervous system and the central nervous system, and different nervous systems contain different contents. Among these areas, the central nervous system, located in the spinal cord and the part of the brain, is the main component of the nervous system, while the peripheral nervous system is the nervous system in other parts, including the cranial and spinal nerves.

Structure of the nervous system.

1. Nervous system: mainly including brain, cerebellum, brainstem, and spinal cord. The nervous system is the general command of the human body, which enables us to carry out normal daily activities and activities of our hands and feet, and can also enable people to have normal functions such as language, thought communication and creativity.

2. Peripheral nervous system: including peripheral nerves, neuromuscular connections, muscles, nerve roots, and plexus. They are commonly found in muscles, limbs, and even internal organs.

The main function of the peripheral nervous system is to make the limbs move normally after receiving instructions from the brain, that is, to be able to write or think and create correctly, but it needs to cooperate with the central nervous system and the peripheral nervous system to unify the body language.

Protects the nervous system.

1. The first thing to do is not to overuse the brain, if the brain is overused, it will lead to overuse, resulting in poor spirits, and it is not conducive to physical health.

2. In terms of diet, you should also pay attention to not eating spicy and unnutritious food, followed by not doing strenuous exercise, otherwise it will affect your health.

Autonomic, transductive, and negative transductional nerves.
