| 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 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 inguinal lymph nodes | Several small nodes deep to the fascia lata and medial to the femoral vein; they receive lymph from the deep structures of the lower limb, from the glans penis and from superficial inguinal nodes; efferents pass to the external iliac nodes. Synonym: nodi lymphatici inguinales profundi. (05 Mar 2000) |
| deep inguinal ring | The opening in the transversalis fascia through which the ductus deferens (or round ligament in the female) and gonadal vessels enter the inguinal canal. Located midway between anterior superior iliac spine and pubic tubercle, it is bounded medially by the lateral umbilical ligament (inferior epigastric vessels) and inferiorly by the inguinal ligament. Indirect inguinal hernias exit the abdominal cavity via the deep inguinal ring Synonym: annulus inguinalis profundus, abdominal ring, annulus abdominalis, internal inguinal ring. (05 Mar 2000) |
| deep intracerebral haemorrhage | <neurology> This implies an intracerebral haemorrhage that has occurred in the deeper structures of the brain, such as the thalamus, basal ganglia, pons, cerebellum and other locations in the brainstem. (27 Sep 1997) |
| deep lamina | In a stratified structure, the stratum which lies beneath all others, furthest from the surface. See: deep layer of levator palpebrae superioris muscle}, deep layer of temporalis fascia. Synonym: lamina profunda, deep lamina. (05 Mar 2000) |
| deep lingual artery | <anatomy, artery> Termination of lingual artery, distribution, muscles and mucous membrane of under surface of tongue. Synonym: arteria profunda linguae, arteria ranina, deep artery of tongue, ranine artery. (05 Mar 2000) |
| deep lingual vein | <anatomy, vein> The principle vein of the tongue that accompanies the deep lingual artery and joins the lingual vein. It drains the body and apex of the tongue, running posteriorly near the median plane; they are often visible through the mucosa on the underside of the tongue, to each side of the frenulum. Synonym: vena profunda linguae. (05 Mar 2000) |
| deep lymphatic vessel | One of the vessels that drain lymph from the deep structures of the body; they tend to follow the courses of blood vessels to reach regional lymph nodes. Synonym: vas lymphaticum profundum. (05 Mar 2000) |
| deep middle cerebral vein | <anatomy, vein> The vein that accompanies the middle cerebral artery in the depths of the lateral sulcus and empties into the basal vein of Rosenthal. Synonym: vena cerebri media profunda. (05 Mar 2000) |
| deep muscles of back | Muscles of the back innervated by the dorsal primary rami of spinal nerves; includes erector spinae, transversospinalis, interspinal, and intertransverse muscles; excludes the superficial back muscles which are appendicular and are innervated by ventral rami, and the trapezius, innervated by the spinal accessory nerve. Synonym: true muscles of back. (05 Mar 2000) |
| deep palmar (arterial) arch | The arterial arch located deep to the long flexor tendons in the hand. It is formed by the terminal part of the radial artery in conjunction with the deep palmar branch of the ulnar artery. The arch gives rise to palmar metacarpal and princeps pollicis arteries. Synonym: arcus palmaris profundus, arcus volaris profundus. (05 Mar 2000) |
