| deep branch | Branch which passes deeply, beneath, or farther from surface; usually in contrast to a superficial branch. Synonym: ramus profundus. (05 Mar 2000) |

| deep branch of the lateral plantar nerve | <anatomy, nerve> Motor branch of lateral plantar nerve supplying lumbricals 2-4, plantar and dorsal interossei, and the adductor hallucis muscles. Synonym: ramus profundus nervi plantaris lateralis. (05 Mar 2000) |
| deep branch of the medial femoral circumflex artery | <anatomy, artery> Distributed to posterior aspect of femoral head and neck. Synonym: ramus profundus arteriae circumflexae femoris medialis. (05 Mar 2000) |
| deep branch of the medial plantar artery | <anatomy, artery> Branch running deep to abductor hallucis, supplying it and the flexor hallucis brevis muscle deep to the artery and the skin of the medial side of the distal foot. Synonym: rami profundi arteriae circumflexae femoris medialis. (05 Mar 2000) |
| deep branch of the radial nerve | <anatomy, nerve> The deep terminal branch of the radial nerve, arises in the cubital region, penetrating and supplying the supinator and continuing with the posterior interosseous artery to supply all the extensor muscles in the forearm. Synonym: nervus interosseus posterior, nervus antebrachii posterior, deep branch of the radial nerve, dorsal interosseous nerve, nervus interosseus dorsalis, posterior antebrachial nerve. (05 Mar 2000) |
| deep branch of the ulnar nerve | <anatomy, nerve> Accompanies deep palmar branch of ulnar artery and deep palmar arch to supply wrist joint, lumbricals 3 & 4, palmar and dorsal interossei adductor pollicis and deep head of flexor pollicis brevis muscles. Synonym: ramus profundus nervi ulnaris. (05 Mar 2000) |
| deep cardiac plexus | The deeper part of the cardiac plexus. Synonym: plexus cardiacus profundus. (05 Mar 2000) |
| deep cell | <embryology> Cells (blastomeres) in the teleost blastula that lie between the outer cell layer and the yolk syncytial layer and are the cells from which the embryo proper is constructed during gastrulation, much studied in the fish, Fundulus. (18 Nov 1997) |
| deep cerebral veins | The numerous veins draining the deep structures of the cerebral hemispheres; they empty into the tributaries of the great cerebral vein. Synonym: venae cerebri profundae. (05 Mar 2000) |
| deep circumflex iliac artery | <anatomy, artery> Origin, external iliac; distribution, muscles and skin of lower abdomen, sartorius and tensor fasciae latae; anastomoses, lumbar, inferior epigastric, superior gluteal, iliolumbar, and superficial circumflex iliac. Synonym: arteria circumflexa iliaca profunda. (05 Mar 2000) |
| deep cortex | <anatomy> Mid cortical region of lymph node, area that is particularly depleted of T lymphocytes in thymectomised animals and is referred to as the thymus dependent area. (18 Nov 1997) |
| deep crural arch | Thickened inferior margin of the transversalis fascia seen as a fibrous band running parallel and posterior (deep) to the inguinal ligament, contributing to the posterior wall of the inguinal canal as it bridges the external iliac-femoral vessels from the iliopectineal arch to the superior pubic ramus. It marks the inferior edge of the deep inguinal ring and the medial margin of the femoral canal. Seen only when the inguinal region is viewed from its internal aspect, it is a useful landmark in laparoscopy of this region, as for repair of inguinal herniae. Synonym: deep crural arch, Thompson's ligament. (05 Mar 2000) |
| deep dorsal sacrococcygeal ligament | <anatomy> The continuation of the posterior longitudinal ligament uniting the sacrum and coccyx. Synonym: ligamentum sacrococcygeum posterius profundum, deep posterior sacrococcygeal ligament. (05 Mar 2000) |
| deep epigastric artery | <anatomy, artery> Origin, external iliac; branches, cremasteric, muscular and pubic; anastomoses, superior epigastric, obturator. With overlying peritoneum, forms lateral umbilical ligament and forms a basis for distinguishing types of inguinal herniae: direct hernias pass medial to the artery; indirect hernias pass laterally. Synonym: arteria epigastrica inferior, deep epigastric artery. (05 Mar 2000) |
| deep fascia | A thin fibrous membrane, devoid of fat, that invests the muscles, separating the several groups and the individual muscles, forms sheaths for the nerves and vessels, becomes specialised around the joints to form or strengthen ligaments, envelops various organs and glands, and binds all the structures together into a firm compact mass. Synonym: fascia profunda. (05 Mar 2000) |
