| 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 mammary branches of lateral cutaneous branches of thoracic spinal 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 thoracic artery | <anatomy, artery> Origin, axillary; distribution, muscles of chest and mammary gland. Synonym: arteria thoracica lateralis, external mammary artery, long thoracic artery. (05 Mar 2000) |
| lateral thoracic vein | <anatomy, vein> A tributary of the axillary vein that drains the lateral thoracic wall and communicates with the thoracoepigastric and intercostal veins. Synonym: vena thoracica lateralis. (05 Mar 2000) |
| long thoracic artery | <anatomy, artery> Origin, axillary; distribution, muscles of chest and mammary gland. Synonym: arteria thoracica lateralis, external mammary artery, long thoracic artery. (05 Mar 2000) |
| long thoracic vein | <anatomy, vein> Incorrect term for lateral thoracic vein. (05 Mar 2000) |
| abducens nerve | <anatomy, nerve> The 6th cranial nerve. The abducens nerve originates in the abducens nucleus of the pons and sends motor fibres to the lateral rectus muscles of the eye. Damage to the nerve or its nucleus disrupts horizontal eye movement control. (12 Dec 1998) |
| abducent nerve | <anatomy> The abducent nerve enervates a muscle which moves the eyeball. Lesions of the sixth cranial nerve result in deviation of the eyeball outward and double vision. Synonym: cranial nerve VI. (27 Sep 1997) |
| accessory nerve | <anatomy, nerve> The accessory nerve enervates the sternocleidomastoid muscles and the trapezius muscles. Lesions of the eleventh result in drooping of the shoulder and inability to rotate the head away from the affected side. Synonym: cranial nerve XI. (27 Sep 1997) |
| accessory nerve lymph nodes | The nodes of the lateral deep cervical group that are located along the accessory nerve; their efferent vessels pass to the supraclavicular lymph nodes. Synonym: companion lymph nodes of accessory nerve, nodi lymphatici comitantes nervi accessorii. (05 Mar 2000) |
| accessory nerve trunk | Part of the accessory nerve formed within the cranial cavity by the union of the cranial and spinal roots, which then divides within the jugular foramen into internal and external branches, the former uniting with the vagus, the latter exiting the foramen as in independent branch which is commonly considered to be the accessory nerve. (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) |
| accommodation of nerve | <anatomy, nerve> The property of a nerve by which it adjusts to a slowly increasing strength of stimulus, so that its threshold of excitation is greater than it would be were the stimulus strength to have risen more rapidly. (05 Mar 2000) |
| accompanying vein of hypoglossal nerve | Runs with the hypoglossal nerve below and lateral to the hyoglossus muscle, emptying usually into the lingual vein. Synonym: accompanying vein of hypoglossal nerve. (05 Mar 2000) |
