Branches of arteries, veins and nerves Flashcards
aorta
right brachiocephalic trunk (right subclav + right cca)
left common carotid artery
left subclavian artery
common carotid artery
bifurcates at C3-4
internal carotid artery (carotid sinus at base)
external carotid artery
branches of internal carotid artery
0 in neck
4 in brain
e.g. ethmoidal artery has branch has anterior meningeal branch
branches of external carotid artery
Superior thyroid Ascending pharyngeal Lingual Facial Occipital Posterior auricular Maxillary Superficial temporal
draining into internal jugular vein
facial + retromandibular vein
draining into external jugular vein
retromandibular vein
draining into retromandibular vein
maxillary + superficial temporal
draining into cavernous sinus
branches of facial e.g. infraorbital -> pteryoid venous plexus (maxillary??) -> cavernous sinus
facial -> ophthalmic -> cavernous sinus
superior petrosal sinus -> cavernous sinus
branch of maxillary artery (1st, 2nd, 3rd parts) of ECA
1st part - middle meningeal artery (foramen spinosum), accessory meningeal artery, inferior alveolar artery
2nd part - anterior and posterior deep temporal arteries
3rd part - posterior superior alveolar, infraorbital
branches of maxillary division of trigeminal nerve
infraorbital greater and lesser palatine posterior superior alveolar nasopalatine palatine
anterior branches of mandibular division of trigeminal nerve
motor to muscles of mastication long buccal (sensory)
posterior branches of mandibular division of trigeminal
auriculotemporal inferior alveolar nerve - mental nerve - nerve to mylohyoid (motor) lingual
branches of facial nerve
chorda tympani posterior auricular temporal zygomatic buccal marginal mandibular cervical
branch of ascending pharyngeal branch of ECA
posterior meningeal artery
