The Autonomic Nervous System

Question 1

What are effectors in the autonomic nervous system?

Answer 1

Neurons that innervate cardiac, smooth muscle, and glands.

Question 2

True or False, the cell bodies of all proganglionic neurons lie in the CNS?

Answer 2

True

Question 3

True or False, the cells bodies of all post ganglionic neurons lie in the CNS?

Answer 3

False:

Question 4

What are the preganglionic neurons of the parasympathic nervous system?

Answer 4

Craniosacral Fibers.

Question 5

What are the post ganglionic neurons of the parasympathetic division?

Answer 5

Terminal Ganglia.

Question 6

What is the sympathetic trunk?

Answer 6

This is a bundle of preganglionic nerve fibers that run along the Vertebral column from the base of the Skull to the coccyx.

Question 7

What are the Gray Communicantes?

Answer 7

The post ganglionic nerve fibers of the sympathetic division.

Question 8

What are White Ramus Communicants?

Answer 8

The preganglionic fibers of the Sympathetic division.

Question 9

True or False, are Nicotinic Receptors always excitatory?

Answer 9

TRUE

Question 10

Which receptor can be e excitatory or inhibitory?

Answer 10

Muscarinic Receptors

Question 11

What are the Cholinergic Receptors?

Answer 11

Nicotinic and Muscarinic.

Question 12

where are Muscarinic Receptors localed ?

Answer 12

On all cholinergic effector cells.

Question 13

What are the Adrenergic Receptors?

Answer 13

Alpha and Beta

Question 14

What effect dos the PSNS have on the body?

Answer 14

Specific and localized.

Question 15

What effect does the SNS have on the body?

Answer 15

Whole body, generalized and diffuse effect.

Question 16

where does ACh get secreted to innervate an effector?

Answer 16

On skeletal muscle, on the post-ganglionic neurors of the Sympathetic system, on the Adrenal Medulla, and on the smooth muscle, Cardiac muscles and glands of T he parasympathetic nervous system.

Question 17

Where is norepinephrine the neurotransmitter at an effector

Answer 17

On the smooth muclel, cardiac muscle, and glands of the sympathetic nervous system.

Question 18

What is Dual Innervation?

Answer 18

When an organ or system is innerveled by both the SNS and the PSNS.

Question 19

What is the benefit of Sympathetic Chain gangila?

Answer 19

It allows for faster communication because it does not have to go from the nerve directly to the organ, and it increases diversity.

Question 20

Explain the blood component of the SNS?

Answer 20

When acytlecholine is released by the Preganglionic neuron to the adrenal medulla, it secretes a combination of 80% epinephrine and 20% norepinephrine into the blood. This takes time to circulate and be absorbed by the body, resulting in a long lasting effect.
