| nerve trunk | A collection of funiculi or bundles of nerve fibres enclosed in a connective tissue sheath, the epineurium. (05 Mar 2000) |
|---|---|
| subclavian lymphatic trunk | It is formed by the union of the vessels draining the lymph nodes of either upper limb, emptying into the thoracic duct at the root of the neck on the left or into the right lymphatic duct. Synonym: truncus subclavius, subclavian duct. (05 Mar 2000) |
| superior trunk of brachial plexus | The nerve bundle formed by the union of the ventral rami of the fifth and sixth cervical nerves and some fibres from the fourth; it contributes fibres to the posterior and lateral cords (fasciculi) of the brachial plexus. Synonym: truncus superior plexus brachialis. (05 Mar 2000) |
| sympathetic trunk | 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) |
| inferior trunk of brachial plexus | The nerve bundle formed by the union of the ventral rami of the eighth cervical and first thoracic nerves; it provides fibres to the posterior and medial cords (fasciculi) of the brachial plexus. Synonym: truncus inferior plexus brachialis. (05 Mar 2000) |
| opening of pulmonary trunk | The opening of the pulmonary trunk from the right ventricle, guarded by the pulmonary valve. Synonym: ostium trunci pulmonalis, pulmonary orifice. (05 Mar 2000) |
| thoracoacromial trunk | <anatomy, artery> Origin, axillary; distribution, muscles and skin of shoulder and upper chest; anastomoses, branches of superior thoracic, internal thoracic, lateral thoracic, posterior and anterior circumflex humeral, and suprascapular. Synonym: arteria thoracoacromialis, acromiothoracic artery, thoracic axis, thoracoacromial trunk. (05 Mar 2000) |
| thyrocervical trunk | A short arterial trunk arising from the subclavian artery, giving rise to the suprascapular (which may instead arise directly from the subclavian artery) and terminating by dividing into the ascending cervical and inferior thyroid arteries. Synonym: truncus thyrocervicalis, thyroid axis. (05 Mar 2000) |
| trunk | <botany> The main stem or body of a tree, considered apart from its roots and branches. (09 Oct 1997) |
| trunk of atrioventricular bundle | The singular initial portion (stem) of the atrioventricular bundle which passes from the atrioventricular node into the right trigone of the fibrous skeleton of the heart and along the periphery of the membranous interventricular septum; upon reaching the muscular interventricular septum, the trunk terminates by dividing into the right and left crura of the atrioventricular bundle. Synonym: truncus fascicularis atrioventricularis. (05 Mar 2000) |
| trunk of corpus callosum | The main arched portion of the corpus callosum. Synonym: truncus corporis callosi. (05 Mar 2000) |
| linguofacial trunk | The common trunk by which the lingual and facial arteries frequently arise from the external carotid artery. Synonym: truncus linguofacialis. (05 Mar 2000) |
| lumbosacral trunk | A large nerve, formed by the union of the fifth lumbar and first sacral nerves, with a branch from the fourth lumbar nerve, which enters into the formation of the sacral plexus. Synonym: truncus lumbosacralis. (05 Mar 2000) |
| aortico-left ventricular tunnel | Congenital connection between the aorta above exit of coronary arteries and the left ventricle. (05 Mar 2000) |
| apicoposterior branch of left superior pulmonary vein | <anatomy, vein> Drains apicoposterior bronchopulmonary segment of superior lobe of left lung. Synonym: ramus apicoposterior venae pulmonalis sinistrae superioris. (05 Mar 2000) |
