Vasculature
these branches off of the subclavian artery supply the brain
what are the internal carotid arteries and vertebral arteries
this nerve innervates the submandibular and sublingual glands
what is the facial nerve
this muscle closes the eye
what is orbicularis oculi
these two components make up the external ear
what are the auricle (pinna) and external auditory canal
Type of muscle that makes up the levator palpebrae
what is skeletal muscle
this artery supplies the deep facial tissues
what is the maxillary artery (branch of the external carotid)
the vestibulocochlear nerve is responsible for these 2 functions
what are hearing and balance
these muscles elevate the mandible
masseter, temporalis, medial pterygoid
After the stapes transmits vibrations to this structure, this structure vibrates and causes movement of fluid in the inner ear
what is the oval window
Innervation of the superior oblique muscle
what is Trochlear nerve (CN IV)
this vein drains blood from the facial vein
what is the internal jugular vein
muscles of the tongue are innervated by this cranial nerve
what is the hypoglossal nerve
this muscle depresses and abducts the eye
superior oblique muscle
the shifting of this gooey substance causes the stereocilia of hair cells to bend, resulting in an action potential that allows the brain to perceive sound
what is the tectorial membrane
Layers of the eyeball from external to internal
what is sclera, choroid, and retina
this branch of the external carotid artery supplies the ear
what is the superficial temporal artery
these functions of the eye are NOT innervated by cranial nerves
what are dilate pupil and keep upper lid open
the soft palate is moved by this muscle
what is palatoglossus muscle
in patients with benign paroxysmal vertigo, otoliths (crystals) move from this area to the semicircular canal
what is the vestibule (two parts of vestibule: saccule and utricle)
responsible for contracting and relaxing the lens
what is smooth muscle fibers (ciliary body)
this is where blood from the scalp, brain and face all mix together
what are the dural sinuses
the nerve loop from the cervical plexus that innervates the infrahyoid muscle group
what is the ansa cervicalis
these muscles attach to the auditory ossicles
what are stapedius and tensor tympani muscles
these two muscles contract via reflex in response to intense sound waves in an attempt to prevent violent ossicle movement, which can cause mid and inner ear damage
what are the stapedius muscle and tensor tympani muscle
responsible for adduction and medial rotation of the eye
what is superior rectus muscle
