Nervous system- SYMPATHETIC and PARASYMPATHETIC

Comparison between Sympathetic and Parasympathetic Nervous system

1. NERVOUS SYSTEM Sympathetic and Parasympathetic Nervous System

2. Autonomic Nervous System ( ANS ) It is a network of neurons connecting the CNS to our internal muscles and organs. It functions continuously whether we are awake, asleep or even under a general anesthetic. It regulates the activities of cardiac muscle, smooth muscle and glands.

3. AUTONOMIC NERVOUS SYSTEM PARASYMPATHETIC SYMPATHETIC

4. Group 1- You and your friends are in the 20 th floor of Landco Bldg. when suddenly, earthquake strikes. Group 2 – You’re quietly walking in the park when an angry bear appear in front of you. Group 3- While your doing your PE activity, You saw your friend suddenly stops and having a hard time to breathe.

5. SYMPATHETIC NERVOUS SYSTEM ( sNS ) It controls the body's responses to a perceived threat and is responsible for the "fight or flight" response or controls the body’s stress response .

6. SYMPATHETIC NERVOUS SYSTEM ( sNS )

7. BODY INDICATIONS during SYMPATHETIC responses 1. Heart rate increases 2. Liver releases glucose 3. Bronchioles are dilated 4. Pupils dilate 5. Adrenal glands secrete epinephrine and norepinephrine 6. Digestion is inhibited 7. Bladder is relaxed

8. parasympathetic NERVOUS SYSTEM ( p NS ) It controls homeostasis and the body at rest and is responsible for the body's "rest and digest" function.

9. parasympathetic NERVOUS SYSTEM ( pNS )

10. BODY INDICATIONS during paraSYMPATHETIC responses 1. Heart rate decreases 2. Liver produces bile 3. Bronchioles are constricted 4. Pupils constrict 5. Adrenal glands stop secreting epinephrine and norepinephrine 6. Digestion is stimulated 7. Bladder contracts

11. AUTONOMIC NERVOUS SYSTEM SYMPATHETIC PARASYMPATHETIC

12. controls the homeostasis and the body at rest and is responsible for the body’s “rest and digest” function. It originates in craniosacral regions. controls the body’s responses to a perceived threat and is responsible for the “fight and flight” response. It sympathetic fibers are thoracolumbar which means it originates between thoracic and lumbar vertebrae. PARASYMPATHETIC NERVOUS SYSTEM (PNS) SYMPATHETIC NERVOUS SYSTEM ( sNS )
