blue
highlighted vessel = superficial temporal artery, branch of external carotid artery
pulse is felt anterior to tragus
highlighted vessel = posterior auricular artery, branch of ECA
highlighted vessel = supratrochlear artery, a branch of ICA
highlighted vessel = facial artery
- originates from ECA and terminatal branch is angular artery
vessel = external jugular vein
- found in posterior triangle, drains into subclavian vein
Maxillary artery and retromandibular vein; extra - facial nerve (parotid
gland labelled)
Internal jugular vein (facial vein labelled)
Middle meningeal artery; crosses the pterion (foramen spinosum labelled)
internal jugular vein
Internal carotid artery (carotid canal labelled)
- Internal jugular veins and subclavian veins (brachiocephalic veins
labelled)

posterior belly of digastric via facial nerve CN VII
Thyrohyoid; hypoglossal nerve CN XII via C1
Omohyoid; C1-C3 anterior rami via ansa cervicalis of cervical plexus
state which infrahyoid muscles lie in the superficial plane or deep plane
superficial: sternohyoid and omohyoid
deep plane: sternothyroid and thyrohyoid
what is the innervation of the sternohyoid and omohyoid and sternothyroid muscles?
the anterior rami of C1-C3 which is carried by a branch of the ansa cervicalis
what is the innervation of the thyrohyoid muscle?
anterior ramus of C1 which is carried within the hypoglossal nerve
facial nerve innervates the stapedius
