15
Q

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

A

IX (Glossopharygeal)

16
Q

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

A

IX (Glossopharygeal)

17
Q

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

A

IX (Glossopharygeal)

18
Q

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

A

X (Vagus)

19
Q

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.

A

X (Vagus)

20
Q

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

A

Agonist

21
Q

Agonists are either

A

hormones or neurotransmitters

22
Q

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

A

Antagonist

23
Q

Parasympathetic Nerves

A
  • constrict pupils
  • slow heartbeat
  • constrict airways
  • stimulate stomach activity
  • inhibit glucose release
24
Q

Sympathetic Nerves

A
  • dilate pupils
  • increase heartbeat
  • relax airways
  • inhibit stomach activity
  • stimulate gluvose release
  • secrete adrenaline
25
Q

Parasympathetic Division

A
  • pupils constrict
  • salivation
  • airways constrict
  • heartrate slows
  • stomach digests
  • intestines digest
  • bladder constricts
  • reproductive system increases blood flow
26
Q

Sympathetic Division

A
  • 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
