Answer 3

Sympathetic, parasympathetic, and enteric

Question 4

What types of fibers do both the SNS and PNS contain?

Answer 4

Afferent and efferent fibers that provide sensory input and motor output, respectively, to the CNS

Question 10

Define the Parasympathetic nervous system

Answer 10

It has the capability to
Constrict pupils.
Contracts bronchioles, and increase secretion.
Decrease heart rate
Dilates blood pressure
Increases peristalsis
Increases salvation

Question 11

Describe the outflow of the ANS

Answer 11

Projects widely to most target tissues and is not as highly focused as the somatic motor system

Question 12

What are the divisions of the ANS?

Answer 12

Sympathetic -Thoracolumbar
Parasympathetic -Craniosacral

Question 13

Has a catecholamine and amines

Answer 13

CATECHOLAMINES

Question 14

Parasympathetic innervation effects

Question 16

What nerves belong to the Somatic Nervous system?

Answer 16

Somatic sensory neuron and somatic motor neuron

Question 17

It’s a neuron that receives impulses and transmits them through the spinal cord to the effector organ cell.

Answer 17

efferent neurons

Question 18

PNS ( Peripheral nervous system )

Answer 18

Except in the brain and spinal cord, all the remaining nerves in other parts of the body

Question 19

What is the terminal neurotransmitter of the parasympathetic nervous system?

Answer 19

Acetylcholine

Question 20

What are the steps for synaptic transmission?

Answer 20

-The neuronal impulse travels down the presynaptic axon to the axon bulb.
-Synaptic vesicles fuse with the axon bulb plasma membrane releasing neurotransmitters.
-The neurotransmitter is released into the synaptic cleft.
-Neurotransmitter bind to receptors on the postsynaptic neuron.
-Sodium ion channels open and the ions enter the postsynaptic neuron
