Where is the main distribution of human nervous tissue?

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.

Summary. 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.

Where is the densest distribution of nerves on the human body**?

The most nerves in the human body are the brain, and the nerves of the human brain are the most hailstormy, 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.

Nerves include the central nervous system, hail town, 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.

And these nerves are almost all connected to the nerves of the brain, so that the brain can have enough control of the physical condition, so the most dense distribution of nerves on the human body is naturally the brain.

Summary. The role of nerves is mainly to innervate the sensory and motor functions of various tissues and organs of the human body. The nervous system is divided into two parts: the central nervous system includes the brain and spinal cord, and the peripheral nervous system includes cranial nerves, spinal nerves, and autonomic nerves

1. Central nervous system 1. Brain: It is an organ that regulates the functions of the body, and is the basis for higher neural activities such as consciousness, spirit, language, learning, memory and intelligence; 2. Spinal cord: It has a strong function of transmitting information, and the brain sends movement information to all parts of the limbs, or the sensory information transmitted by various parts of the human body to the brain.

In addition, the spinal cord, as a low-level center, can innervate simple reflex activities, that is, activities where the reflex arc does not pass through the brain, such as stretch reflex, muscle inhibition reflex, superficial reflex, bladder urination reflex, rectal defecation reflex, etc. 2. Peripheral nervous system 1. Cranial nerves: 12 pairs of cranial nerves are emanated, which mainly innervate the motor and sensory functions of various tissues and organs of the head and face; 2. Spinal nerves:

The spinal cord gives rise to 31 pairs of spinal nerves, including 8 pairs of cervical nerves, 12 pairs of thoracic nerves, 5 pairs of lumbar nerves, and 5 pairs of sacrum.

What are the functions of nerves distributed throughout the body?

The role of nerves is mainly to innervate the sensory and motor functions of various tissues and organs of the human body. 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, and the peripheral nervous system includes cranial nerves, spinal nerves and autonomic nerves: 1. Central nervous system 1

It is an organ that regulates the functions of the body, and is the basis for higher neural activities such as consciousness, spirit, language, learning, memory and intelligence. 2. Spinal cord: It has a strong function of transmitting information, and the brain sends movement information to all parts of the limbs, or the sensory information transmitted from various parts of the human body to the brain. In addition, the spinal cord, as a low-level center, can innervate simple reflex activities, that is, activities where the reflex arc does not pass through the brain, such as stretch reflex, muscle inhibition reflex, superficial reflex, bladder urination reflex, rectal defecation reflex, etc.

2. Peripheral nervous system 1. Cranial nerves: 12 pairs of cranial nerves are emanated, which mainly innervate the motor and sensory functions of various tissues and organs of the head and face; 2. Spinal nerves: The spinal cord gives out a total of 31 pairs of spinal nerves, including 8 pairs of cervical nerves, 12 pairs of thoracic nerves, 5 pairs of lumbar nerves, and 5 pairs of sacrum.

to the sacral nerve, and 1 pair of caudal nerves. The spinal nerve is a mixed nerve, which mainly innervates the movement and sensory functions of the body and internal organs. 3. Autonomic nerve: divided into sympathetic nerve and parasympathetic nerve, the sympathetic nerve is sent out by the spinal nerve, which is responsible for stimulating various activities of internal organs, cardiovascular and glands.

The sensory nerves of the paracone, which are divided into the brain and the spine, often travel in the cranial nerves or spinal nerves, and mainly inhibit the activity of the viscera, cardiovascular and glandular barricades.

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

Nerve endings: human organs.
