| arteria ciliaris posterior longa | long posterior ciliary artery |
| arteria circumflexa humeri posterior | <anatomy, artery> Origin, axillary; distribution, muscles and structures of shoulder joint; anastomoses, anterior circumflex humeral, suprascapular, thoracoacromial, and profunda brachii. Synonym: arteria circumflexa humeri posterior, posterior humeral circumflex artery. (05 Mar 2000) |
| arteria communicans posterior | <anatomy, artery> Origin, internal carotid; distribution, optic tract, crus cerebri, interpeduncular region, and hippocampal gyrus; anastomoses, with posterior cerebral to form the cerebral arterial circle (circle of Willis). Synonym: arteria communicans posterior. (05 Mar 2000) |
| arteria conjunctivalis posterior | <anatomy, artery> One of a series of branches from the arterial arches of the upper and lower eyelids that supplies the conjunctiva. Synonym: arteria conjunctivalis posterior, conjunctival arteries. (05 Mar 2000) |

Synonym: arteria recurrens tibialis posterior. (05 Mar 2000) |
| arteria spinalis posterior | <anatomy, artery> Origin, vertebral; distribution, medulla, spinal cord, and pia mater; anastomoses, spinal branches of intercostal arteries. Synonym: arteria spinalis posterior. (05 Mar 2000) |
