Week 1 Dry Flashcards
3 compartments of the neck and what they are enclosed by
vascular
visceral
vertebral
musculofascial collar
contents of vertebral compartment
vertebrae and postural muscles
contents of visceral compartment
thyroid and parathyroids, pharynx, larynx, trachea and oesophagus
contents of vascular compartment
major blood vessels (carotids and jugulars) and vagus nerve
how many cervical vertebrae are there
7
which vertebral spinous process sticks out as a bony landmark
C7 (vertebra prominens)
features to define a cervical vertebrae
- bifurcated spinous process)
- small body
- relatively large vertebral foramen
which cervical vertebrae has not got a bifid process
C7
2 triangles of the neck
anterior and posterior
boundaries of anterior triangle
inferior border of mandible
anterior border of SCM
midline of neck
boundaries of posterior triangle
posterior border of SCM
anterior border of trapezius
inferiorly the clavicle
which triangle contains the common carotid
anterior
which triangle contains the internal jugular
anterior
which triangle contains the external jugular
posterior
which triangle contains cranial nerves VII, IX-XII
anterior
attachments of SCM
2 heads: manubrium of sternum and clavicle to the mastoid process of temporal bone
action of left sternocleidomastiod
tilt head left, turn face right
action of trapezius
retract scapula and rotate glenoid cavity superiorly
motor innervation of SCM
spinal accessory nerve (XI)
SCM pain and proprioception innervation
C2 and C3
motor innervation of trapezius
spinal accessory nerve (XI)
roots of brachial plexus
C5-T1
what part of the body does the brachial plexus serve
the upper limb
4 further divisions of anterior triangle
submental
digastric/submandibular
carotid
muscular
boundaries of submental triangle
neck midline to hyoid bone to anterior belly of digastric
boundaries of submandibular triangle
mandible to anterior belly of digastric to posterior belly of digastric/stylohyoid
boundaries of carotid triangle
SCM to posteriori belly of digastric/stylohyoid to superior belly of omohyoid
boundaries of muscular triangle
hyoid to midline to super belly of omohyoid
branching from aorta to common carotid on left side
aorta –> CCA
branching from aorta to common carotid on right side
aorta –> braciocephalic –> CCA
three branches off the aorta
brachiocephalic, left CCA, left subclavian
muscle that lies over neck most superficially
platysma
contents of carotid sheath
common carotid artery and internal jugular vein and vagus nerve
innervation of platysma for motor and sensory
facial nerve (VII)
level of CCA bifurcation
C4
landmark at CCA bifurcation
thyroid cartilage prominence
which branch of CCA supplies the outside of the skull
external carotid
which carotid gives of branches in the skull
internal carotid
what gland does the ECA pass through
parotid gland
two terminal branches of ECA given off in parotid gland
superficial temporal and maxillary
which carotid is the facial artery a branch off
ECA
which carotid supplies the thyroid
ECA
origin of IJV in brain
jugular venous (sigmoid) sinous
which structures branches can be remembered by two zulus buggered my cocaine
facial nerve
where do you see the facial artery
wiggly and down on the side of the chin area
which layer of the scalp carries the blood supply from the ECA
loose connective tissue
which exit of the skull does the IJV emerge from
jugular foramen
where does the EJV drain
scalp and face
the EJV runs/superficial/deep to the SCM
superficial
which is bigger, IJV or EJV
IJV
order of contents in carotid sheath
outiside to inside
IJV –> vagus nerve –> CCA
where does the phrenic nerve lie in relation to the carotid sheath
posterior
