| 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 cervical artery | <anatomy, artery> Origin, terminal branch of costocervical trunk (along with superior intercostal artery); distribution, posterior deep muscles of neck; anastomoses, branches of occipital, ascending cervical, and vertebral. 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 cervical vein | <anatomy, vein> Large vein running with the artery of the same name between the semispinalis capitis and semispinalis cervicis draining the deep muscles at the back of the neck and emptying into the brachiocephalic or the vertebral vein.

| 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) |
