Classification of Peripheral Nervous System in Teachers' Recruitment Preparation

Psychology is a very important part of the teacher recruitment examination over the years. As outlined in the first chapter, the most complex and difficult to understand is the nervous system. This part of knowledge involves physiological psychology, comparative medicine, which is boring, but if you comb it with the teacher, you will find it is not difficult. The central nervous system is relatively easy to understand, but what about the peripheral nervous system?

First of all, we should understand that the nervous system is everywhere in our body, not only the brain, but also our internal organs and limbs. Therefore, the nervous system is divided into peripheral nervous system and central nervous system. The central nervous system includes the spinal cord and the brain. The peripheral nervous system consists of nerves distributed in limbs and organs.

The peripheral nervous system is divided into three parts: cranial nerve, spinal nerve and autonomic nerve.

The cranial nerves emanate from the brain, *** 12 pairs. Followed by olfactory nerve; Optic nerve; Oculomotor nerve; Trochlear nerve; Trigeminal nerve; Abduction nerve; Facial nerve; Auditory nerve; Glossopharyngeal nerve; Vagus nerve; Accessory nerve; Sublingual nerve You can use a formula to help you remember. One smell, two look, three eyes moving, four strokes, five forks, six abduction, seven faces, eight listening, nine tongue swallowing, vague, sublingual.

The spinal nerve originates from the spinal cord and passes through the intervertebral foramen. It can be divided into four categories: body sensation, visceral sensation, body movement and visceral movement.

The autonomic nervous system includes sympathetic nerve and parasympathetic nerve, which are functionally opposite. Sympathetic nerve is used by the human body to deal with emergencies. For example, when you are fighting with someone or are afraid or angry, the sympathetic nerve will act immediately, which will make your heart beat faster, let the liver release more blood sugar, let the muscles come in handy, temporarily slow down or even stop the activities of digestive organs, thus mobilizing the whole body's strength to deal with this unexpected situation. We need to calm ourselves down when the emergency is over. At this time, the parasympathetic nerve will play a role. Play a balance role, inhibit the excessive excitement of various organs of our body, and let these organs get the necessary rest.

This part examines you in the form of multiple-choice questions in the exam. For example, which of the following belong to the cranial nerves? Or which of the following is the function of sympathetic nerve? Everyone can recite one-on-one
