| 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 circumflex iliac vein | <anatomy, vein> Corresponds to the artery of the same name, and empties, near or in a common trunk with the inferior epigastric vein, into the external iliac vein. Synonym: vena 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 dorsal vein of clitoris | A tributary of the vesical venous plexus; it runs a course deep to the fascia on the dorsum of the clitoris. Synonym: vena dorsalis clitoridis profunda. (05 Mar 2000) |
| deep dorsal vein of penis | A vein on the dorsum of the penis deep to the fascia of the penis; it is a tributary to the prostatic venous plexus. Synonym: vena dorsalis penis profunda. (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 epigastric vein | <anatomy, vein> Corresponds to the artery of the same name and empties into the external iliac vein just proximal to the inguinal ligament. Synonym: vena epigastrica inferior, deep epigastric vein. (05 Mar 2000) |
| deep facial vein | <anatomy, vein> The communicating vein that passes from the pterygoid venous plexus of the infratemporal fossa to the facial vein; it is devoid of valves. Synonym: vena faciei profunda. (05 Mar 2000) |
| deep femoral vein | <anatomy, vein> The vein that accompanies the deep femoral artery, receiving perforating veins from the lateral and posterior aspects of the thigh. It joins the femoral vein in the femoral triangle, usually in common with the medial and lateral circumflex femoral veins. Synonym: vena profunda femoris. (05 Mar 2000) |
| deep fibular nerve | <anatomy, nerve> One of the terminal branches of the common peroneal nerve, arising at the fibular neck and passing into the anterior compartment of the leg; it supplies the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius muscles in the leg, then crosses the ankle joint to supply the muscles on the dorsum of the foot (extensors hallucis and digitorum brevis) becoming cutaneous to innervate adjacent sides of the great and second toes. Synonym: nervus fibularis profundus, nervus peroneus profundus, anterior tibial nerve, deep fibular nerve. (05 Mar 2000) |
| deep flexor muscle of fingers | <anatomy, muscle> Origin, anterior surface of upper third of ulna; insertion, by four tendons, piercing those of the superficialis, into base of distal phalanx of each finger; action, flexes distal interphalangeal joint of fingers; nerve supply, ulnar and median (anterior interosseous muscle). Synonym: musculus flexor digitorum profundus, deep flexor muscle of fingers, musculus flexor profundus. (05 Mar 2000) |
| deep head of flexor pollicis brevis | The head of short flexor of the thumb that arises from the trapezoid and capitate bones and transverse carpal ligaments. It is innervated by the deep ulner nerve, and considered by many to be the first palmar interosseous muscle. Synonym: caput profundum musculi flexoris pollicis brevis. (05 Mar 2000) |
| deep hypothermic arrest | Stoppage of electrical and mechanical cardiac activity that occurs when the heart is cooled. (05 Mar 2000) |
