| spermatic cord | A group of structures which go through the inguinal canal to the testis. The structures include the vas deferens, arteries, veins, lymphatic vessels, and nerves. (12 Dec 1998) |
|---|---|
| spermatic cord torsion | Torsion of the spermatic cord caused usually by incomplete attachment of the epididymis to the testis or by inclusion of the cord within the tunica vaginalis. Faulty development of various anatomical components of the testes is also a cause. It occurs most frequently in childhood and adolescence. (12 Dec 1998) |
| nephrogenic cord | A longitudinal dorsolateral tract of mesoderm derived from intermediate mesoderm; the primordium for both mesonephric and metanephric tubules. (05 Mar 2000) |
| dental cord | <dentistry> An aggregation of epithelial cells forming the rudimentary enamel organ. (05 Mar 2000) |
| oblique cord | A slender band extending from the lateral part of the coronoid process of the ulna distad and laterad to the radius immediately distal to the bicipital tuberosity. Synonym: chorda obliqua, oblique cord, round ligament of elbow joint, Weitbrecht's cord, Weitbrecht's ligament. (05 Mar 2000) |
| omphalomesenteric cord | A persistent yolk stalk in the form of a solid cord of tissue connecting ileum to umbilicus. Synonym: omphalomesenteric cord. (05 Mar 2000) |
| testicular cord | A group of structures which go through the inguinal canal to the testis. The structures include the vas deferens, arteries, veins, lymphatic vessels, and nerves. (12 Dec 1998) |
| tethered cord syndrome | <syndrome> Abnormal low positioning (below the L2 vertebrae) of the distal spinal cord (conus medullaris) by the filum terminale. May be associated with incontinence, progressive motor and sensory impairment in the legs, pain, and scoliosis. (05 Mar 2000) |
| true vocal cord | One of Ferrein's cords; the sharp edge of a fold of mucous membrane overlying the vocal ligament and stretching along either wall of the larynx from the angle between the laminae of the thyroid cartilage to the vocal process of the arytenoid cartilage; the vocal folds are the agents concerned in voice production. Synonym: plica vocalis, chorda vocalis, labium vocale, true vocal cord, vocal cord, vocal shelf. (05 Mar 2000) |
| false vocal cord | One of the pair of folds of mucous membrane stretching across the laryngeal cavity from the angle of the thyroid cartilage to the arytenoid cartilage; they enclose a space called the rima vestibuli or false glottis. Synonym: plica vestibularis, false vocal cord, plica ventricularis, ventricular band of larynx, ventricular fold. (05 Mar 2000) |
| umbilical cord | The flexible structure, giving passage to the umbilical arteries and vein, which connects the embryo or foetus to the placenta. (12 Dec 1998) |
| lateral cord of brachial plexus | In the brachial plexus, the bundle of nerve fibres formed by the anterior divisions of the superior and middle trunks which is located lateral to the axillary artery. This cord gives off the lateral pectoral nerve and terminates by dividing into the musculocutaneous nerve and the lateral root of the median nerve. Synonym: fasciculus lateralis plexus brachialis. (05 Mar 2000) |
| lumbar cord | That part of the cord that consists of the five lumbar segments and gives rise to the five pairs of lumbar nerves. Synonym: pars lumbalis medullae spinalis. (05 Mar 2000) |
| accessory portion of spinal accessory nerve | <anatomy, nerve> The roots of the accessory nerve which arise from the medulla; the nerve fibres of the cranial root join the intracranial portion of the vagus nerve and are distributed to the pharyngeal plexus, providing the motor innervation of the soft palate (except the tensor veli palati) and the pharynx. Synonym: pars vagalis nervi accessorii, radices craniales, accessory portion of spinal accessory nerve, cranial roots, vagal part of accessory nerve, vagal part. (05 Mar 2000) |
| anterior spinal artery | <anatomy, artery> Origin, intracranial part of vertebral; distribution, spinal cord and pia mater; anastomoses, spinal of intercostal and lumbar arteries. Synonym: arteria spinalis anterior. (05 Mar 2000) |
