| dorsal | 1. Pertaining to the back or to any dorsum. 2. Denoting a position more toward the back surface than some other object of reference, same as posterior in human anatomy, superior in the anatomy of quadrupeds. Origin: L. Dorsalis, from dorsum = back (18 Nov 1997) |
| dorsal accessory olivary nucleus | A detached part of the olivary nucleus dorsal to the latter's main body. Synonym: nucleus olivaris accessorius dorsalis. (05 Mar 2000) |
| dorsal artery of clitoris | One of the two terminal branches of the internal pudendal artery in the female, the other being the deep artery of the clitoris. Synonym: arteria dorsalis clitoridis. (05 Mar 2000) |
| dorsal artery of foot | <anatomy, artery> Continuation of anterior tibial artery after crossing ankle; branches, lateral tarsal, arcuate, dorsal metatarsal; a continuation of the anterior tibial; anastomoses, with the lateral plantar to form the plantar arch. Synonym: arteria dorsalis pedis, dorsal artery of foot. (05 Mar 2000) |
| dorsal artery of nose | Origin, ophthalmic; external artery of the nose; distribution, skin of side of root of nose; anastomoses, angular artery. Synonym: arteria dorsalis nasi, arteria nasi externa, dorsal artery of nose, external artery of nose. (05 Mar 2000) |

| dorsal branch | <anatomy, nerve> The smaller, posteriorly-directed major terminal branch (with the ventral primary ramus) of all 31 pairs of mixed spinal nerves, formed at the intervertebral foramen and turning abruptly posteriorly to divide into lateral and medial branches, both of which will supply the deep (true) muscles of the back. The medial branch (rami medialis ) of the dorsal primary ramus also supplies articular branches to the zygopophyseal joints and the periosteum of the vertebral arch. In the neck and upper back, the medial branch continues through the deep and superficial back muscles to supply overlying skin; in the lower back, the lateral branch does this. Nomina Anatomica lists dorsal primary rami as "rami dorsales" for each group of spinal nerves: 1) cervical (nervorum cervicalium ), 2) thoracic (nervorum thoracicorum ), 3) lumbar (nervorum lumbalium ), 4) sacral (nervorum sacralium ), and 5) coccygeal (nervi coccygei ). Synonym: ramus dorsalis nervorum spinalium, ramus dorsalis, rami posteriores nervorum spinalium, dorsal branch, posterior primary division. (05 Mar 2000) |
| dorsal branch of the lumbar artery | <anatomy, artery> Terminal branch (with ventral branch) of the 4-5 lumbar arteries, distributed to lumbar portion of back, posterior vertebral column, and spinal cord and environs. Synonym: ramus dorsalis arteriae lumbalium. (05 Mar 2000) |
| dorsal branch of the posterior intercostal arteries 3-11 | Terminal branch (with ventral branch) of the 3rd through 11th posterior intercostal arteries, distributed to thoracic portion of posterior vertebral column, spinal cord and environs, and back. Synonym: ramus dorsalis arteriarum intercostalium posteriorum III-XI. (05 Mar 2000) |
| dorsal branch of the posterior intercostal veins 4-11 | Major tributary of the 4th through 11th posterior intercostal veins; area drained is the same as that supplied by the dorsal branch of posterior intercostal arteries. Synonym: ramus dorsalis venarum intercostalium posteriorum IV-XI. (05 Mar 2000) |
| dorsal branch of the subcostal artery | <anatomy, artery> Terminal branch (with ventral branch) of subcostal artery, distributed to posterior vertebral column, spinal cord and environs, and back at the T12-L1 vertebral level. Synonym: rami dorsales arteriae subcostalis. (05 Mar 2000) |
| dorsal branch of the superior intercostal artery | <anatomy, artery> Branches of the 1st and 2nd posterior intercostal arteries which arise as branches of the supreme intercostal artery. The distribution is the same as for the dorsal branches of the other posterior intercostal arteries at the T1-T2 vertebral level. Synonym: rami dorsales arteriae intercostalis supremae.

| dorsal calcaneocuboid ligament | <anatomy> See: bifurcate ligament. (05 Mar 2000) |
