Peripheral Nervous System

Answer 4

The rest of the nerves
1. sensory division
2. motor divison
- somatic NS
- autonomic NS
- sympathetic
- parasympathetic

Question 5

Parasympathetic NS

Answer 5

REST AND DIGEST
Fibers leave the spinal cord in the cranial and sacral regions
- leave straight from the spinal cord and top/bottom
- innervate the inner visceral organs

Question 6

Sympathetic NS

Answer 6

FIGHT OR FLIGHT
Preganglionic nerves leave from all along the spinal
- fibers leave the spinal cord in the thoracic and lumbar region
- viceral abdominal organs

Question 7

Neurotransmitters

Answer 7

Chemical messengers that the cell uses to make a decision
- released in the synapse
- either active of inhibit
- chemicals released at the synaptic cleft
EX- acetylcholine, norepinephrine, dopamine, etc.

Question 8

Receptor location

Question 9

Autonomic NS- effects

Answer 9

Eye- dilation or constriction
heart rate- increase or decrease
blood pressure- elevate or depress
gastrointestinal tract- increase activity or decrease activity

Question 10

Blocking agents

Answer 10

Ach- released at the synapse in order to release the action potential at the effector organ

Question 11

Effects of the ANS

Answer 11

• skeletal muscle is not an effector
• skeletal muscle are not directly innervated by the ANS
• fibers leave the spinal cord in the thoracic and lumbar regions (SNS)
• fiber leave the spinal cord in the cranial and sacral region (PNS)
• neurons reside inside the gastrointestinal tract (enteric NS)
