| branch of facial n.; supplies muscles in the cheek, upper lip, and corner of mouth | buccal branches |
| branch of facial n.; supply muscles of lower lip and chin | marginal mandibular branches |
| branch of facial n.; supply the platysma | cervical branches |
| where does the ext. carotid a. bifurcate | C4 |
| v. formed by the union of the superficial temporal and maxillary veins | retromandibular v. |
| which is the only cranial n. that travels through foramen magnum | spinal accessory n. |
| anterior circulation of brain, arises at carotid bifurcation and travels through carotid foramen | internal carotid arteries |
| posterior circulation of brain, arises from subclavian a. and travels through the transverse processes of cervical vertebrae | vertebral arteries |
| ophthalmic a., posterior communicating a., anterior choroidal a., anterior cerebral a., middle cerebral a. | internal carotid a. branches |
| provides abundant opportunities for collateral flow but anatomical variants are common; made up of ACA, Acomm, Pcomm, and internal carotid a. | circle of willis |
| part of circle of willis, deep to optic n., terminal branch of internal carotid a. | anterior cerebral a. (ACA) |
| terminal branch of internal carotid a. that is found behind the temporal lobe | middle cerebral a. (MCA) |
| arise from top of basilar a., near oculomotor n. | posterior cerebral a. (PCA) |
| part of circle of willis, where the anterior cerebral arteries anastomose, common place for aneurysms | anterior communicating a. (Acomm) |
| part of circle of willis, links anterior and posterior circulation, connects internal carotids to PCA | posterior communicating a. (Pcomm) |
| branch of basilar a. | superior cerebellar a. |
| superficial veins of cerebral hemispheres drain mainly into the superior sagittal sinus and cavernous sinus, deep veins drain mainly into superior sagittal sinus, nearly all veins of brain reach int. jugular veins | venous drainage of cerebellar hemispheres |
| a. that travels with optic n. in optic canal, 1st branch is the central retinal a. | ophthalmic a. |
| large v. that goes through inferior orbital fissure | inferior ophthalmic v. |

| ramifies on promontory of middle ear and is derived form CN IX, innervates mucous membrane lining walls and contents of middle ear | tympani plexus |
| innervates semicircular canals, vestibule, cochlea, vestibular ganglia, internal acoustic meatus | vestibulocochlear n. |
| supplies larynx with motor and sensory innervation | vagus n. |
| which a. travels through aperture for inferior branch of superior laryngeal n. and associated a. as well as internal and external laryngeal nerves | laryngeal a. |
| these arteries supply blood to the larynx | superior laryngeal a. and inferior laryngeal a. |
