Fundamentals of Anatomy Flashcards
which bone of the cranium is the ear associated with?
the temporal bone
what are the special sensory functions of the ear?
hearing
balance
what connects the middle ear to the nasopharynx?
the eustachian tube
what is the role of the external ear in hearing?
collects sound waves and directs to the middle ear
what is the role of the middle ear in hearing?
conducts and amplifies vibrations toward the inner ear
what is the role of the inner ear in hearing?
converts the vibrations into action potentials
what is the special sensory function of the nose?
smell
what arteries give off branches to supply the cranial cavity?
internal carotid artery
vertebral artery
what arteries give off branches to supply the face?
internal carotid artery
external carotid artery
what arteries give off branches to supply the neck?
external carotid artery
subclavian artery
what is the mnemonic for remembering the branches of the external carotid artery, from proximal to distal?
some anatomists like freaking out poor medical students
what are the branches of the external carotid artery, from proximal to distal?
superior thyroid ascending pharyngeal lingual facial occipital posterior auricular maxillary superficial temporal
what does the venous drainage of the cranial cavity follow?
the dural venous sinuses
where does all venous drainage from the cranial cavity eventually drain?
the internal jugular vein
why is the danger triangle of the face called this?
veins in this area can potentially carry superficial infections back into deeper areas of the head and neck

what sensory ganglia of the head and neck is associated with CN V?
trigeminal ganglion
what sensory ganglia of the head and neck is associated with CN VII?
geniculate ganglion
what sensory ganglia of the head and neck is associated with CN VIII?
