28
Q

Which section of the tooth contains the nerves and blood vessels?

A

29
Q

Which nerve provides innervation to the parotid gland

A

Glossopharyngeal nerve (IX)

30
Q

31
Q

Which two glands share a capsule?

A

Mandibular and sublingual glands

32
Q

What does the Vagus nerve control in the rumen?

A

33
Q

What do issues swallowing often arise because of?

A

Brain lesions

34
Q

Function of the myenteric plexus

A

Regulation of smooth muscle contractions in the GIT

Q

What effect does the parasympatheic system have on gut function

A

Enhances it to increase the rate of digestion i.e. gastric motility & enzyme secretion (rest/digest)

36
Q

What effect does the sympatheic system have on gut function

A

Reduces gut function to divert blood supply to muscles & heart (fight/run)
