Autonomic Nervous System II Week 4

Question 1

Sympathetic Trunk =

Answer 1

Sympathetic Chain Ganglia

Question 2

basal ganglia are not located where?

Answer 2

PNS

Question 3

Collateral Ganglia are not located where?

Answer 3

near the ganglia

Question 4

3 ways a neuron can synapse:

Answer 4

1. at the same level
2. you can synapse up or down a level
3. axon follows the same pathways by bypasses ganglia all together and to a collateral ganglion which makes it a splanchnic nerve

Question 5

comes from the CNS comes out through the ventral root bc its motor, goes through white communicans, synapses and sends message out through gray communicans

Answer 5

synapse at same level

Question 6

sends information leaving the ganglia

Answer 6

gray communicans

Question 7

follow the same pathway as before but you go up a level to an above ganglion and synapses above a level and axon extends further

Answer 7

synapse up a level

Question 8

Why is it referred to as a spinal nerve

Answer 8

contains both white and gray rami

Question 9

sensory alwasy comes in to dorsal/motor and always leaves ventral; one neuron in one out

Answer 9

Somatic reflex arc

Question 10

sensory comes in from a single neuron dorsal root (Visceral sensory, broad) and synapses in horn and then 2 neurons send info out; one neuron in and two out

Answer 10

Autonomic Reflex arc

Question 11

ACh is always the _________-

Answer 11

neurotransmitter

Question 12

Cholingic is always the _________

Answer 12

receptor

Question 13

binding that imitates ACh, gives us an effect that seems similar to an ACh

Answer 13

Muscarine receptors

Question 14

what binds to muscarine receptors?

Answer 14

muscarine and ACh bind okay but nicotine does NOT

Question 15

Two types of Cholinergic Receptors

Answer 15

Muscarinic and Nicotinic receptors

Question 16

two main classes of Adrenergic receptors

Answer 17

A1

Question 18

Inhibitory effects; opposes A1

Answer 18

A2
