| lateral pyramidal fasciculus | Those fibres of the pyramidal tract that cross to the opposite side in the pyramidal decussation and descend in the dorsal half of the lateral funiculus of the spinal cord; they are distributed throughout the length of the spinal cord to interneurons of the zona intermedia of the spinal gray matter. See: pyramidal tract. Synonym: tractus corticospinalis lateralis, tractus pyramidalis lateralis, crossed pyramidal tract, fasciculus corticospinalis lateralis, fasciculus pyramidalis lateralis, lateral corticospinal tract, lateral pyramidal fasciculus.

| lateral cutaneous branches of ventral primary ramus of thoracic spinal nerves | Branches arising in approximately the anterior axillary line at the level of the second through sixth intercostal spaces. Synonym: rami mammarii laterales nervorum intercostalium, lateral cutaneous branches of intercostal nerves. (05 Mar 2000) |
| lateral spinal sclerosis | Considered by many to be a subgroup of motor neuron disease; a slowly progressive degenerative disorder of the motor neurons of the cerebral cortex, resulting in widespread weakness on an upper motor neuron basis; spasticity, hyperreflexia, and Babinski signs are present, but not fasciculation potentials, nor any electrodiagnostic evidence of a lower motor neuron lesion. Synonym: lateral spinal sclerosis. (05 Mar 2000) |
| lateral mammary branches of lateral cutaneous branches of intercostal nerves | Branches arising from the lateral cutaneous branches of the ventral primary rami of spinal nerves (intercostal nerves) T-3 to T-6 which run anteriorly to supply the lateral aspect of the breast. Synonym: rami mammarii laterales rami cutanei lateralis nervorum thoracicorum, rami mammarii laterales rami cutanei lateralis nervorum intercostalium, lateral mammary branches of lateral cutaneous branches of intercostal nerves. (05 Mar 2000) |
| lateral mammary branches of lateral thoracic artery | <anatomy, artery> Branches of the lateral thoracic artery which extend around the lateral borders of the pectoral muscles to supply the lateral aspect of the breast and mammary gland. Synonym: rami mammarii laterales arteriae thoracicae lateralis. (05 Mar 2000) |
| lateral vein of lateral ventricle | A vein draining deep portions of the temporal and parietal lobes; it runs in the lateral wall of the lateral ventricle to terminate in the superior thalamostriate vein. Synonym: vena ventriculi lateralis lateralis, lateral atrial vein, lateral vein of lateral ventricle. (05 Mar 2000) |
| gangliated cord | One of the two long ganglionated nerve strands alongside the vertebral column that extend from the base of the skull to the coccyx; they are connected to each spinal nerve by gray rami and receive fibres from the spinal cord through white rami connecting with the thoracic and upper lumbar spinal nerves. Synonym: truncus sympathicus, gangliated cord. (05 Mar 2000) |
| genital cord | One of a pair of mesenchymal ridges bulging into the caudal part of the celom of a young embryo and containing the mesonephric and paramesonephric duct. (05 Mar 2000) |
| medial cord of brachial plexus | In the brachial plexus, the bundle of nerve fibres formed by the anterior division of the inferior trunk which lies medial to the axillary artery; it gives off the medial pectoral nerve, the medial brachial cutaneous, and medial antebrachial cutaneous, nerves and end by dividing into the medial root of the median nerves and the ulnar nerve. Synonym: fasciculus medialis plexus brachialis. (05 Mar 2000) |
| vitelline cord | A persistent yolk stalk in the form of a solid cord of tissue connecting ileum to umbilicus. Synonym: omphalomesenteric cord. (05 Mar 2000) |
| vocal cord nodules | Small, circumscribed, bilateral, beadlike enlargements on the vocal cords caused by overuse or abuse of the voice; often reversible by voice therapy. Synonym: singer's nodes, singer's nodules, teachers' nodes. (05 Mar 2000) |
| vocal cord paralysis | Paralysis of one or both of the vocal cords. (12 Dec 1998) |
| central cord syndrome | <syndrome> Quadriparesis most severely involving the distal upper extremities, with or without sensory loss and bladder dysfunction, usually due to ischemia from osteophytic or traumatic compression of the central part of the cervical spinal cord and/or artery. (05 Mar 2000) |
| gubernacular cord | The content of the gubernacular canal, usually composed of remnants of dental lamina and connective tissue. (05 Mar 2000) |
| Weitbrecht's 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) |
