superficial structures of the neck & posterior cervical triangle Flashcards
the omohyoid does what to the hyoid
depresses it
covers the sternocleidomastoid and trapezius
investing fascia
great auricular nerve
(c2, c3)
transverse or superficial nerve
(c2, c3)
supraclavicular nerve
(c3, c4)
lesser or small occipital nerve
(c2)
near the clavicle, there is a deep fascia that forms
suprasternal space of burns
space that contains jugular venous arch and lymph node
suprasternal
covers the back of pharynx and esophagus
buccopharyngeal fascia
covers thyroid gland, and is attached with larynx, also known as the dangerous layer
pretracheal layer
posterior to esophagus, and also known as the danger space of the neck
retopharyngeal recess
the carotid sheath posteriorly blends with
the prevertebral fascia
carotid sheath superficially blends with
superficial layer of cervical fascia
covers the muscles of the floor posterior trianger
axillary sheath
what is found in the postero-lateral boundary of the anterior triangle
anterior border of the SCM
what is found in the floor of the posterior cervical triangle
prevertebral fascia
this artery arises from the thyrocervical branch of subclavian artery
transverse(superficial) cervicla artery
this is a branch of the thyrocervical artery, also passes across the lower part of the posterior triangle inferior to the superficial cervical artery
suprascapular artery
anterior boundary of the occipital triangle
SCM
the most important nerve crossing the occipital triangle
accessory nerve cnXI
floor of the supraclavicular(subclavian) triangle
formed by the posterior border of the SCM

trapezius
The ____ part of the posterior triangle is known as the “carefree” area due to its lack of nerves and vessels
occipital

anterior
The posterior triangle of the neck can be subdivided into the subclavian/omoclavicular/supraclavicular triangle and the ____ triangle
occipital triangle
The supraclavicular triangle contains the subclavian artery and subclavian vein as well as the ____
brachial plexus
CN XI can be found under what muscle?
sternocleidomastoid
The deep infrahyoid (or “strap”) muscles are the thyrohyoid and _____ muscles
sternothyroid
