Neuromodulation PPT, Part 2: Reflection Concept (P103)

The process by which the human body responds to various stimuli through the nervous system is called reflex.

basic patterns of neural activity

Can stimulation only come from outside?

Stimulation can come from the outside, such as enemies, food, etc., or it can come from the body, such as pain reflexes caused by lesions in internal organs.

Neuromodulation PPT, Part 3: Discussion

How do you think the nervous system regulates urinary activity in adults? What evidence supports your opinion?

Relevant information

After a person's bladder (receptor) senses the urge to urinate, it transmits it to the spinal cord through the afferent nerve, and then from the spinal cord to the brain. The brain begins to process the information. Is there a place to urinate? If so, it notifies the spinal cord through the efferent nerve. Complete the urination activity. Otherwise, tell the bladder to hold on.

discuss

How do you think the nervous system regulates urinary activity in adults? What evidence supports your opinion?

Evidence: (1) Babies’ brains are not fully developed yet and they defecate at any time.

(2) If an adult suffers an accident and the spinal cord is broken from the chest, the defecation and urination center in the lower part of the spinal cord loses control of the brain, resulting in incontinence.

Neuromodulation PPT, Part 4: Summary of this section

1. Reflection

2. Reflection arc

3. Sometimes higher-level nerve centers can control some lower-level nerve centers.

Neuromodulation PPT, Part 5: Practice

(1) The flower disk of a sunflower always faces the sun.

(2) The bird was frightened and flew away.

(3) Objects suddenly appear in front of the eyes, making people's eyes dizzy.

(4) People will salivate when they hear bayberry being talked about.

(5) The Venus flytrap quickly closes up when it encounters the stimulation of a small insect.

2. The basic way the nervous system regulates various physiological activities of the human body is-----()

A． Produce excitement B. reflex activity

C. Reflection arc D. nerve impulse

3. The basic structure that completes reflexive activities is _______. It includes ＿＿＿,＿＿＿,＿__,＿＿＿,＿＿. Without any one link, reflex activities cannot proceed normally.

4. Babies urinate unconsciously because ()

A． Incomplete development of the urinary center in the spinal cord

B. Signals from the spinal cord are not conducted to the brain

C. The reflex arc of the urinary reflex is incompletely developed

D. Incomplete brain development

5. Which of the following organs is both a receptor and an effector ( )

A． Salivary glands b. Cornea C. Ligament D. bladder
