| thoracic limb | The shoulder, arm, forearm, wrist, and hand. Synonym: membrum superius, superior limb, thoracic limb, upper extremity. (05 Mar 2000) |
| thoracic longissimus muscle | <anatomy, muscle> Origin, with iliocostalis and from transverse processes of lower thoracic vertebrae; insertion, by lateral slips into most or all of the ribs between angles and tubercles and into tips of transverse processes of upper lumbar vertebrae, and by medial slips into accessory processes of upper lumbar and transverse processes of thoracic vertebrae; action, extends vertebral column; nerve supply, dorsal primary rami of thoracic and lumbar spinal nerves. Synonym: musculus longissimus thoracis, musculus longissimus dorsi, thoracic longissimus muscle. (05 Mar 2000) |
| thoracic nerves | The twelve pairs of spinal nerves that arise from the thoracic segments of the spinal cord, each pair leaving the vertebral column below the correspondingly numbered vertebra. They innervate the body wall of the thorax and abdomen. (12 Dec 1998) |
| thoracic nucleus | A column of large neurons located in the base of the posterior gray column of the spinal cord, extending from the first thoracic through the second lumbar segment; it gives rise to the dorsal spinocerebellar tract of the same side. Synonym: nucleus thoracicus, Clarke's column, Clarke's nucleus, dorsal nucleus, nucleus dorsalis, Stilling's column, Stilling's nucleus. (05 Mar 2000) |
| thoracic outlet syndrome | <syndrome> Condition due to compromise of blood vessels or nerve fibres between the armpit (axilla) and base of the neck. (12 Dec 1998) |
| thoracic part of aorta | The part of the descending aorta that supplies structures as far down as the diaphragm. Synonym: pars thoracica aortae, aorta thoracica, thoracic part of aorta. (05 Mar 2000) |
| thoracic part of oesophagus | The part of the oesophagus between the superior thoracic aperture and the diaphragm. Synonym: pars thoracica oesophagi. (05 Mar 2000) |
| thoracic part of spinal cord | The part of the spinal cord which consists of the twelve thoracic segments of the spinal cord from which the twelve pairs of thoracic nerves originate. Synonym: pars thoracica medullae spinalis, segmenta medullae spinalis thoracica. (05 Mar 2000) |
| thoracic-pelvic-phalangeal dystrophy | Hereditary hypoplasia of the thorax, associated with pelvic skeletal abnormality. Synonym: asphyxiating thoracic chondrodystrophy, Jeune's syndrome, thoracic-pelvic-phalangeal dystrophy. (05 Mar 2000) |
| thoracic respiration | Respiration effected chiefly by the action of the intercostal and other muscles that raise the ribs, causing expansion of the chest. Synonym: costal respiration. (05 Mar 2000) |
