Question 9

Cranial Nerves with Parasympathetic System:

Answer 9

• III (Oculomotor Nerve)
• VII (Facial Nerve)
• IX (Glossopharygeal)
• X (Vagus)

Question 10

Movement of the eye muscles, constriction of the pupil, focusing with the eyes & the position of the upper eyelid.

Answer 10

III (Oculomotor Nerve)

Question 11

Works with other cranial nerves to control eye movements and support sensory functioning.

Answer 11

III (Oculomotor Nerve)

Question 12

carries nerve fibers that control facial movement and expression.

Answer 12

VII (Facial Nerve)

Question 13

carries nerves that are involved in taste to the anterior 2/3 of the tongue and producing tears (lacrimal gland)

Answer 13

VII (Facial Nerve)

Question 14

It is one of the four cranial nerves that has sensory, motor, and parasympathetic functions.

Answer 14

IX (Glossopharygeal)

Question 15

It originates from the medulla oblongata and terminates in the pharynx.

Answer 15

IX (Glossopharygeal)

Question 16

It provides motor, parasympathetic and sensory information to your mouth and throat.

Answer 16

IX (Glossopharygeal)

Question 17

Among its many functions, the nerve helps raise part of your throat, enabling swallowing.

Answer 17

IX (Glossopharygeal)

Question 18

is the longest cranial nerve in the body, containing both motor and sensory functions in both the afferent and efferent regards.

Answer 18

X (Vagus)

Question 19

The nerve travels widely throughout the body affecting several organ systems and regions of the body, such as the tongue, pharynx, heart, and gastrointestinal system.

Answer 19

X (Vagus)

Question 20

produces a response by binding to a receptor on the cell.

Answer 20

Agonist

Question 21

Agonists are either

Answer 21

hormones or neurotransmitters

Question 22

opposes the action by binding to the receptor and blocks these receptors and renders them ineffective

Answer 22

Antagonist

Question 23

Parasympathetic Nerves

Answer 23

• constrict pupils
• slow heartbeat
• constrict airways
• stimulate stomach activity
• inhibit glucose release

Question 24

Sympathetic Nerves

Answer 24

- dilate pupils - increase heartbeat - relax airways - inhibit stomach activity - stimulate gluvose release - secrete adrenaline

Question 25

Parasympathetic Division

Answer 25

- pupils constrict - salivation - airways constrict - heartrate slows - stomach digests - intestines digest - bladder constricts - reproductive system increases blood flow

Question 26

Sympathetic Division

Answer 26

- pupils dilate - saliva inhibited - airways dilate - heart rate increases - stomach inhibits digestion - liver releases glucose - intestines inhibit digestion - kidneys release adrenaline - bladder relaxes - reproductive system decreases blood flow
