Description

"The Composition of the Nervous System" Regulation of Human Life Activities PPT Courseware 3

learning target:

1. Describe the composition and function of the nervous system and neurons.

2. Explain that the coordinated movements of various parts of the human body are mainly achieved by the regulation of the nervous system.

There are nerve connections between the brain and limbs and eyes, between the brain and internal organs, and between the spinal cord and limbs.

The nervous system is composed of the brain, spinal cord, and the nerves they send out.

Brain - the most advanced part of the nervous system

Brain: has the function of managing different parts of the human body

Cerebellum: Responsible for the coordination of human body movements, coordinating muscle activities, such as walking, running, etc., and maintaining body balance.

Brainstem: Mainly controls the movement of the circulatory system and respiratory system, such as breathing, heartbeat, blood pressure, etc. It can maintain the normal operation of life activity functions without any conscious interference.

Spinal cord - continuation of brainstem

The spinal cord is located in the spinal canal of the spine and is the lower-level part of the central nervous system. It has conductive and reflective functions;

The brain's control of spinal cord activity: There are many nerve centers in the spinal cord that can independently complete some reflex activities. However, the low-level reflex centers in the spinal cord control unconscious reactions and are generally controlled by the brain.

peripheral nervous system

Cranial nerves: 12 pairs, coming from the brain, mainly controlling the sensation and movement of various organs in the head and neck.

Spinal nerves: 31 pairs, coming from the spine, mainly controlling the sensation and movement of the neck, limbs and internal organs of the body.

2. Someone is unsteady when standing with his eyes closed, shakes when walking, and cannot complete delicate movements. The possibility of developing lesions is ( )

A. Brainstem B. Cerebrum C. Spinal cord D. Cerebellum

3. Clinical "vegetative" usually refers to patients who only have breathing and heartbeat but no other vital signs. The part of the brain that is generally not damaged in this type of patient is ( )

A. Brain B. Cerebellum

C. Brainstem D. Cerebral cortex

4. Which of the following statements about neurons is incorrect ( )

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

B. Neurons can sense stimuli, generate and conduct excitement

C. Neurons are composed of cell bodies and processes

D. Neurons include nerve fibers and nerve endings.

Thinking extension

If you were a neurologist, what advice would you give people on how to protect their nervous system in their daily lives? What neurological diseases can result if not properly protected?

1. During training, you should make sufficient preparations before exercising.

2. When playing with classmates, do not slap your head and neck.

3. Eat more foods that are good for nervous system health.

4. Go to bed on time to give your nervous system adequate rest.

5. Regular exercise can make nerve cells respond flexibly, increase the excitability of the cerebral cortex, and maintain the health of the nervous system.

6. Diseases related to the nervous system include neurasthenia, cerebral thrombosis, epilepsy, neurodermatitis, cerebral palsy, neurological deafness, etc.
