Autonomic Nervous System Functions - CORRECT ANSWER -1. Regulate the heart
2. Regulate the secretory glands (salivary, gastric, sweat, and bronchial)
3. Regulate the smooth muscles (bronchi, blood vessels, urogenital system, and gastrointestinal
tract)
Parasympathetic Nervous System Functions - CORRECT ANSWER -1. Slowing the heart rate
2. Increasing the gastric secretions
3. Emptying the bladder
4. Emptying the bowel
5. Focusing the eye for near vision
6. Constricting the pupil
7. Contracting the bronchial smooth muscle
Parasympathetic nervous system drugs - CORRECT ANSWER -1. Digestion of food
2. Excretion of waste
3. Control of vision
4. Conservation of energy
Sympathetic Nervous System Functions - CORRECT ANSWER -1. Regulation of the
cardiovascular system
-Maintaining blood flow to the brain
-Redistributing blood
, -Compensating for the loss of blood
2. Regulation of the body temperature
-Regulates blood flow to the skin
-Promotes the secretion of sweat
-Induces piloerection (erection of hair)
3. Implementation of the "fight-or-flight" reaction
-Increasing heart rate and blood pressure
-Shunting blood away from the skin and viscera
-Dilating the bronchi
-Dilating the pupils
-Mobilizing stored energy
Homeostatic Objectives of the SNS - CORRECT ANSWER -1. Maintenance of blood flow to
the brain
2. Redistribution of blood flow during exercise
3. Compensation for loss of blood, primarily by causing vasoconstriction
SNS Body Temperature Regulation - CORRECT ANSWER -1. Regulates blood flow to the skin
-Dilating surface vessels: Accelerates heat loss
-Constricting cutaneous vessels: Conserves heat
2. Promotes secretion of sweat glands: Helps the body cool
3. Induces piloerection: Promotes heat conservation
fight or flight response - CORRECT ANSWER -1. Increasing heart rate and blood pressure
2. Shunting blood away from the skin/viscera and into skeletal muscle
3. Dilating the bronchi to improve oxygenation
4. Dilating the pupils
