Circulatory Flashcards
Important divisions of subclavian artery
vertebral a.
internal thoracic a.
thyrocervical a.
costocervical a.
dorsal scapular a.
supplies the intercostal space
costocervical trunk (superior intercostals and deep cervical arteries)
thyrocervical/cervicothyroid trunk divisions
transverse cervical a.
suprascapular a.
inferior thyroid a.
supplies the abdominal wall
superior epigastric artery (termination of internal thoracic artery)
components of the carotid sheath
internal carotid artery
internal jugular vein
vagus nerve (X)
located at the bifurcation of internal and external common carotid artery that help monitor systemic blood pressure
carotid sinus baroreceptors innervated by the glossopharyngeal nerve (IX)
major supply for the brain and its branches
internal carotid artery
* anterior and middle cerebral arteries: anastamose with anterior and *posterior communicating arteries = circle of willis (communicates with vertebral a. via basilar and posterior cerebral a.)
* ophthalmic artery
supplies the orbital area and lacrimal gland
ophthalmic artery
most common location of berry aneurysm
anterior communicating and anterior cerebral artery
most common location of stroke
middle cerebral artery
Major branches of external carotid artery (7)
maxillary artery
posterior auricular artery
facial artery
lingual artery
occipital artery
superior thyroid artery
ascending pharyngeal artery
branches of the superior thyroid artery and what they supply (4)
infrahyoid artery - infrahyoid mucle
superior laryngeal artery - muscles of the larynx
sternocleidomastoid artery - SCM muscle
cricothyroid artery - thyroid gland
ascending pharyngeal artery supplies the…
pharynx, soft palate, and meninges
Branches of the lingual artery and what they supply
suprahyoid artery - suprahyoid muscle
deep lingual artery - tongue
dorsal lingual artery - tongue, soft palate, tonsils
sublingual artery - floor of the mouth, mylohyoid muscle, and sublingual gland
supplies the tongue
deep lingual artery, dorsal lingual artery
supplies the soft palate
dorsal lingual artery (lingual), ascending pharyngeal artery, ascending palatine artery (facial), lesser palatine artery (maxillary)
supplies the thyroid gland
cricothyroid artery (superior thyroid a)
supplies the mylohyoid muscle
sublingual artery (lingual), submental artery (facial), mylohyoid artery (mandibular division of maxillar artery)
