Where are the main nerves of the human body concentrated?

Located in the cranial cavity and spinal canal, they are the most concentrated and complex parts of nerve tissue.

The nervous system is the entire body of the human body that is made up of nervous tissue.

It is mainly composed of neurons.

The nervous system is made up of two parts: the central nervous system and the peripheral nervous system, which is located throughout the body.

The central nervous system, which includes the brain and spinal cord, is located in the cranial cavity and spinal canal, respectively, and is the most concentrated and complex part of the nervous tissue. There are centers that control various physiological functions. The peripheral nervous system includes various nerves and ganglia.

Among them, the ones connected to the brain are called cranial nerves, the spinal nerves that are connected to the spinal cord, and the autonomic nerves that innervate the internal organs are called autonomic nerves. Various types of nerves are connected to other organ systems through their terminals.

It should be noted that the cervical spine is not the most concentrated place of human nerves, but it is a very important part, the cervical vertebrae is connected with the foramen magnum of the occipital bone, and the cervical segment is the part where the spinal cord begins, and the top is the medulla oblongata, which is the center of human life, so if the cervical spine injury hurts the spinal cord, the consequences are very serious, and even life-threatening.

The entire human body is clustered around the nervous system, and the central nervous system alone has hundreds of billions of nerve cells, so let's take a look at the basic structure of the nervous system.

It's the brain and the spinal cord that pulls the central nervous system.

The nerves connected to the brain are called cranial nerves, there are 12 pairs, most of which are distributed in the sensory organs, ** and muscles of the head, and only a pair of very long vagus nerves descend along the neck, distributed in most of the chest cavity and the internal organs of the abdominal cavity.

It is mainly distributed in the brain and spine.

There are nerve tissues in various tissues and organs, and there are many nerve tissues in the organs.

Peripheral nerves, which refer to the dendrites and axons of nerve cells, are used to receive and transmit information because nerve cells are found throughout the body. The inner cerebral cortex and the white matter of the spinal cord are the most concentrated distribution of nerve endings, and the fibrous terminals of all peripheral nerves terminate in other structures to form this unique structure called nerve endings, which are widely distributed in the epidermis, cornea, serous membrane, muscle and other connective tissues.

If there is damage to the peripheral nerves, local massage can be carried out in time to promote blood circulation. In addition, some drugs to improve neuronutrition such as methylcobalamin and vitamin B group can also be used. Peripheral nerves are divided into sensory nerve endings and nerve endings of this movement, so different nerve endings are damaged and different symptoms are produced.

White matter in the medial cerebral cortex and spinal cord.

Hello, the nervous system is divided into two parts: the central nervous system and the peripheral nervous system.

The central nervous system includes the brain and spinal cord. The brain and spinal cord are located in the central axis of the human body, and they are surrounded by skulls and vertebrae. The peripheral nervous system includes cranial, spinal, and autonomic nerves.

There are 12 pairs of cranial nerves, which mainly innervate the sensory and motor functions of the head and facial organs. The ability to see things around us, hear sounds, smell smells, taste, and have expressions of joy, anger and sorrow all depend on the function of these 12 pairs of cranial nerves.

There are 31 pairs of spinal nerves, including 8 pairs of cervical nerves, 12 pairs of thoracic nerves, 5 pairs of lumbar nerves, 5 pairs of sacral nerves, and 1 pair of caudal nerves. The spinal nerves originate from the spinal cord and innervate the sensational, motor, and reflexes of the body and limbs.

Autonomic nerves, also known as splanchnic nerves, are mainly found in visceral, cardiovascular, and glandular areas. Heartbeat, breathing, and digestive activity are all regulated by it. The autonomic nerve is divided into two categories: sympathetic and parasympathetic, and the two are mutually resistant and coordinated with each other to form an organic whole with tacit understanding, so that the internal organs can adapt to the needs of the internal and external environment.

All parts, just your elbows, are not afraid of squeezing, afraid of stinging; The cornea of the eye is afraid of foreign bodies, not cold. The division of labor is different, so the functions are different.

There are all kinds of parts, big nerves in the brain, spine and so on.

It's distributed in a lot of places.

Where there is a feeling, there must be.

The part with the most nerves in the human body is the brain, and the nerves of the human brain are the most, because the whole person's thinking, activities, learning, and all behaviors are controlled by the brain, and the brain is equivalent to a terminus, and then it is equivalent to the headquarters, directing the work of other nerves, of course, the brain has the most nerve distribution and the most dense.

Nerves include central and peripheral nerves. The central nervous system includes the brain and spinal cord. Peripheral nerves include 12 pairs of cranial nerves and 31 pairs of spinal nerves, but they all contain somatic and splanchnic nerves.

Almost all of these nerves are connected to the nerves of the brain, so that the brain can have enough control of the physical condition, so the most densely distributed place of nerves on the human body is naturally the brain.

The most densely distributed areas of nerves on the human body are**, especially in the hands**. The brain is where the fibers of nerve tissue meet.

It's your back cervical vertebrae, where the nerves in your brain are most densely linked. So don't slap someone else's back of the neck, the back of your neck. Don't hit the back of the head either, it's the cerebellum.

The whole body is all over the body, and the places where the senses are sensitive are more abundant.

Nerve endings: human organs.

The cerebral cortex is the nerve center that regulates the body's activities.
