Synonym: arteria cervicalis profunda. (05 Mar 2000) |

| deep cervical fascia | Fascia of the neck; it is divided into an external or investing layer (superficial lamina) that surrounds the neck and encloses the trapezius and sternocleidomastoid muscles, a middle or pretracheal layer in relation to the infrahyoid muscles, and a deep or prevertebral layer applied to the vertebrae and axial muscles. Synonym: fascia cervicalis, deep fascia of neck, fascia cervicalis profunda. (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 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) |
| deep fascia of arm | The deep fascia of the arm; it is continuous proximally with the pectoral fascia and the fascia covering the deltoid; distally it is continuous with the antebrachial fascia. Synonym: fascia brachii, deep fascia of arm. (05 Mar 2000) |
| deep fascia of forearm | It is continuous with the brachial fascia; in the region of the wrist it forms two thickened bands, the extensor and flexor retinacula. Synonym: fascia antebrachii, deep fascia of forearm, fascia of forearm. (05 Mar 2000) |
| deep fascia of leg | Fascia of the leg; it is continuous with the fascia lata and is attached proximally to the patella, ligamentum patellae, the tubercle and condyles of the tibia, and the head of the fibula; distally it is thickened to form the flexor and extensor retinacula. Synonym: fascia cruris, deep fascia of leg, fascia of leg. (05 Mar 2000) |
| deep fascia of neck | Fascia of the neck; it is divided into an external or investing layer (superficial lamina) that surrounds the neck and encloses the trapezius and sternocleidomastoid muscles, a middle or pretracheal layer in relation to the infrahyoid muscles, and a deep or prevertebral layer applied to the vertebrae and axial muscles. Synonym: fascia cervicalis, deep fascia of neck, fascia cervicalis profunda. (05 Mar 2000) |
| deep fascia of thigh | The strong deep fascia of the thigh, enveloping the muscles of the thigh and thickened laterally as the iliotibial track. Synonym: fascia lata, broad fascia. (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 gray layer of superior colliculus | A layer of myelinated fibres, the deepest layer of the colliculus superior, delimiting the latter from the central gray substance surrounding the cerebral aqueduct. Synonym: stratum album profundum. (05 Mar 2000) |
