| digital reflex | <clinical sign> In latent tetany mild mechanical stimulation of the trigeminal nerve causes severe pain, flexion of the terminal phalanx of the thumb and of the second and third phalanges of one or more of the fingers when the volar surface of the terminal phalanx of the fingers is flicked. Synonym: digital reflex, Hoffmann's reflex, snapping reflex. (05 Mar 2000) |
|---|---|
| digital subtraction angiography | Computer-assisted roentgenographic angiography permitting visualization of vascular structures without superimposed bone and soft tissue density; images made before and after contrast injection allow subtraction (separation and removal) of opacities not enhanced by the contrast medium. Other image-processing can be performed. Contrast material may be injected intravenously or in lower-than-usual amount intra-arterially. (05 Mar 2000) |
| digital veins | See: dorsal digital veins of foot, palmar digital veins, plantar digital veins. (05 Mar 2000) |
| digital whorl | <botany> A ring of leaves, bracts or floral parts borne at the same level on a main stem. (13 Nov 1997) |
| dorsal digital artery | <anatomy, artery> One of the collateral digital branches of the dorsal metatarsal arteries in the foot, and/or of the dorsal metacarpal arteries in the hand. Synonym: arteria digitalis dorsalis. (05 Mar 2000) |
| dorsal digital veins of foot | They receive intercapitular veins from the plantar venous arch, join to form four common dorsal digital veins, and terminate in the dorsal venous arch. Synonym: venae digitales dorsales pedis, dorsal digital veins of toes. (05 Mar 2000) |
| dorsal digital veins of toes | They receive intercapitular veins from the plantar venous arch, join to form four common dorsal digital veins, and terminate in the dorsal venous arch. Synonym: venae digitales dorsales pedis, dorsal digital veins of toes. (05 Mar 2000) |
| infantile digital fibromatosis | Multiple fibrous flesh-coloured nodules on the extensor aspect of the terminal phalanges of adjacent digits of infants and young children which often recur after attempted excision, do not metastasize, and may spontaneously regress in two to three years; composed of spindle cells containing cytoplasmic inclusions believed to be derived from myofibrils. Synonym: infantile digital fibromatosis. (05 Mar 2000) |
| tendinous chiasm of the digital tendons | Crossing of the tendons, the passage of the tendons of the flexor digitorum profundus (flexor digitorum longus in the foot) through the interval left by the decussation of the fibres of the tendons of the flexor digitorum superficialis (flexor digitorum brevis in the foot). Synonym: chiasma tendinum, Camper's chiasm. (05 Mar 2000) |
| extensor digital expansion | A triangular tendinous aponeurosis including the tendon of the extensor digitorum centrally, interosseus tendons on each side, and a lumbrical tendon laterally. It covers the dorsal aspect of the metacarpophalangeal joint and the proximal phalanx. Synonym: dorsal hood, extensor aponeurosis, extensor expansion. (05 Mar 2000) |
| fibrous digital sheaths of foot | Fibrous sheaths of the toes, the tubular fibrous layer enclosing the synovial sheath and the tendons of the long and short flexors of the toes and the flexor hallucis longus in the digits; they are composed of annular and cruciform parts. Synonym: vaginae fibrosae digitorum pedis. (05 Mar 2000) |
| fibrous digital sheaths of hand | Fibrous sheaths of the digits of the hand, the tubular fibrous layers that enclose the synovial sheaths and the superficial and deep flexor tendons and the tendon of the flexor pollicis longus in their passage along their respective digits; they are composed of annular and cruciform parts. Synonym: vaginae fibrosae digitorum manus. (05 Mar 2000) |
| abdominopelvic splanchnic nerves | Visceral branches of the sympathetic trunks conveying presynaptic sympathetic fibres to and visceral afferent fibres from the prevertebral ganglia and para-aortic/hypogastric plexuses for the innervation of viscera located below the diaphragm. The greater, lesser, lowest, lumbar, and sacral splanchnic nerves belong to this group. (05 Mar 2000) |
| accelerator nerves | Certain of the cardiopulmonary splanchnic nerves establishing the sympathetic innervation of the heart; originating from ganglion cells of the superior, middle, and inferior cervical ganglion of the sympathetic trunk, the unmyelinated efferent fibres of the accelerator nerve's stimulate an increase in the heart rate. (05 Mar 2000) |
| accessory phrenic nerves | Accessory nerve strands that arise from the fifth cervical nerve, often as branches of the nerve to the subclavius, passing downward to join the phrenic nerve. Synonym: nervi phrenici accessorii. (05 Mar 2000) |
