Head & Neck Flashcards
describe extent of scalp
describe layers of the scalp
explain diploe
3 components on a skull bone
compact bone
periosteum
spongy bone (diploe)
list the cutaneous nerves of the scalp
INNERVATION of scalp anterior to auricles is by branches of all 3 divisions of trigeminal
Posterior to auricles is by spinal cutaneous nerves (C2 and C3)
describe the distribution of dermatomes of the scalp
Trigeminal nerve = CNV1 , CNV2, CNV3
Spinal nerves = anterior (C2/3) and posterior rami (C2/3)
describe the arterial supply of scalp
Supratrochlear
Supraorbital
Superficial temporal
Occipital
describe venous drainage of the scalp
Superficial temporal
Posterior auricular
Occipital
describe cutaneous innervation of the face
Auriculotemporal
Buccal
mental
Trigeminal
Facial - VII
describe branches of trigeminal nerve innervating the cutaneous innervation of face
V1 - ophthalmic
V2 - maxillary
V3 - mandibular
describe course of arteries which supply face
Facial artery
describe course of veins which drain face
list main muscles (and their function) of facial expression
list the deficient movements when the facial nerve is injured/damaged
describe structure, function and topographic anatomy of the parotid gland and its duct including innervation
describe relaxation of the external carotid artery and facial nerve and its branches to the parotid gland
describe general organisation of the neck with respect to fascia, layers and triangles
define anterior triangles of neck in terms of borders and list their contents
define posterior triangles of neck in terms of borders and list their contents
name subdivisions of the anterior triangles

name and identify the strap muscles of the neck (infrahyoid muscles)
strap muscles location in relation to thyroid gland
identify the arterial supply of the thyroid gland
describe relations of arterial supply of thyroid gland with branches of the vagus nerve (be aware in surgery)
