Q

What are the different types of sensory fibres that the cranial nerve carries?

A
  • General sensory (ordinary sensations – touch, temperature, pain etc
  • Special sensory ( vision/ hearing/ olfaction/ taste)

Olfaction: the action or capacity of smelling; the sense of smell.

Q

How do sympathetic fibres reach those regions supplied by cranial nerves?

A

Postganglionic fibres from the sympathetic chain form a plexus and hitch a ride with blood vessels.

A

Purely sensory

19
Q

What fibres does V2 contain? Maxillary division

A

Purely sensory

20
Q

What type of fibres does V3 contain?

Mandibular division

A

Sensory and motor

21
Q

Sensory innervation to the face and anterior part of the scalp is supplied by which nerve?

A

Branches of the trigeminal nerve

22
Q

What are the following face muscles?

A
23
Q

Which nerve is the facial nerve?

A

Cranial nerve 7

24
Q

What type of fibres does the facial nerve contain?

A

Contains motor fibres

Sensory fibres

Parasympathetic fibres

25
Q

Which foramen does the facial nerve emerge from?

A

Stylomastoid foramen - gives motor branches to muscle for facial expression

26
Q

Which structures pass through the parotid gland?

A

External carotid artery enters into the parotid to give off its terminal branches

Retromandibular vein

Facial nerve

27
Q

What is the name of the two triangles?

A
28
Q

What is contained within the carotid sheath?

A

Carotid arteries

Internal jugular

Vagus nerve

29
Q

Where do the right and left common carotid arteries arise from?

A
  • Right side – arises from brachiocephalic artery
  • Left side – arises directly from arch of the aorta
30
Q

What does the ECA and the ICA supply?

A

ECA stays “external” and supplies neck, face, scalp

ICA goes “internal” (inside cranial cavity) and supplies the brain

31
Q

What is the internal jugular vein?

A

•Big vein running alongside the carotid arteries in the neck draining blood from brain

32
Q

What is the external jugular vein?

A

•the thin vein draining much of the region external to the cranial cavity.

33
Q

What forms the cervical plexus and what does it supply?

A

Ventral rami from C1 to C5 - from this plexus arises sensory and motor branches innervating skina and muscles of the neck region

34
Q

What are the strap muscles?

A

Suprahyoid and infrahyoid

35
Q

What is the purpose of the strap muscles?

A

Moves hyoid bone

The hyoid bone is linked to the skeleton of the voice box and is moved by the supra and infrahyoid muscles

36
Q

What does the superior thyroid artery arise from?

A

Branch of the external carotid artery

37
Q

Where does the inferior thyroid artery arise from?

A

The subclavian artery

38
Q

What is the nerve supply of the thyroid gland?

A

External laryngeal n (branch of Vagus)

Recurrent laryngeal n (branch of Vagus)

39
Q

Where do the superoir, middle and the inferior thyroid veins drain?

A

Superior - IJV

Middle - IJV

Inferoir - Brachiocephalic
