Part One: Course Knowledge Points

Knowledge point 1: The brain, spinal cord and nerves form the nervous system

[Example] (2017 Hebei Cangzhou Simulation) The following statement about the composition of the nervous system is correct ()

A. The cranial nerves and spinal nerves together form the nerve center

B. The central nervous system consists of three parts: the cerebrum, cerebellum, and brainstem.

C. The peripheral nervous system includes the spinal cord and spinal nerves

D. Nervous system includes central nervous system and peripheral nervous system

Analysis The nervous system includes the central nervous system and the peripheral nervous system. The central nervous system consists of the brain and spinal cord, which in turn includes the cerebrum, cerebellum and brainstem. The peripheral nervous system consists of cranial nerves and spinal nerves.

Answer D

Knowledge point 2: Neuron is the basic unit of structure and function of the nervous system

1. Structure of Neurons

(1)Illustration

2. Basic functions of neurons

Receive stimulation, generate impulses, and conduct impulses.

3. Several important concepts

(1) Nerve impulse: After neurons are stimulated, they will produce a bioelectric change, which can be conducted along the cell membrane in a certain direction. This conductable bioelectrical change is called a nerve impulse, or impulse for short.

(2) Ganglion: In the peripheral nervous system, the location where neuron cell bodies appear concentratedly.

(3) Nerve: In the peripheral nervous system, it is a structure composed of some neuron processes gathered into bundles and surrounded by a connective tissue membrane.

(4) Gray matter: In the central nervous system, the areas where neuron cell bodies are concentrated are dark in color and are called gray matter.

(5) White matter: In the central nervous system, the place where a large number of neuron processes gather in bundles is white and bright, which is called white matter.

Nervous system and neuromodulation PPT, Part 2 content: Examination points

Test points: Analysis of the structure and function of the nervous system

[Example] (2017·Shandong Qingdao Simulation) Which of the following statements about the structure and function of the human nervous system is correct ()

A. Neuron is the basic unit of structure and function of the nervous system

B. The spinal cord is the highest-level center that regulates human physiological activities.

C. The main function of the cerebellum is to coordinate respiratory rate

D. The central part of the nervous system includes the brain and cranial nerves

Analysis The nervous system consists of the brain and spinal cord and the nerves they send out. The brain and spinal cord form the central nervous system, and the cranial nerves and spinal nerves form the peripheral nervous system. The basic unit of structure and function of the nervous system is the neuron; the cerebral cortex is the highest-level center that regulates human physiological activities; the main function of the cerebellum is to coordinate movements and maintain body balance.

Answer A

Nervous system and neuromodulation PPT, part 3: detailed explanation of textbook questions

Demonstrate the discussion topic "The Overall Form and Structural Composition of the Human Nervous System"

1. Name the components of the nervous system.

Tips The nervous system is made up of the brain and spinal cord and the nerves that emanate from them.

2. Try to describe the shape and location of the brain and spinal cord.

Tip: The brain is the main part of the central nervous system and is located in the cranial cavity. The spinal cord is part of the central nervous system. It is located in the spinal canal composed of vertebrae. It is long and cylindrical, slightly deviated from front to back, and surrounded by a membrane. It is consistent with the curvature of the spine.

3. Try to describe the morphology and distribution of cranial and spinal nerves.

Tip: The cranial nerves are paired left and right nerves that come from the brain, with a total of 12 pairs. Cranial nerves connect different parts of the brain and enter and exit the cranial cavity through holes in the base of the skull. These nerves are mainly distributed in the sensory organs, skin, muscles, etc. of the head, and some extend into the internal organs of the chest and abdomen. There are many paired nerves called spinal nerves on both sides of the spinal cord, 31 pairs in total, which are distributed to the skin, muscles and internal organs of the body. Responsible for sensation and movement below the neck.
