| thoracic spinal nerves | Twelve nerves on each side, mixed motor and sensory, supplying the muscles and skin of the thoracic and abdominal walls. Synonym: nervi thoracici. (05 Mar 2000) |
|---|---|
| thoracic spine | The thoracic region of the vertebral column; the thoracic vertebrae as a whole; that part of the vertebral column which enters into the formation of the thorax. (05 Mar 2000) |
| thoracic spine fracture | <orthopaedics> Bony fracture of one of the twelve thoracic vertebrae. (27 Sep 1997) |
| thoracic splanchnic nerves | Splanchnic nerves arising from the thoracic portion of the sympathetic trunks; the upper thoracic splanchnic nerves (from T1 to T4 or 5) pass to viscera above the diaphragm (mainly heart and lungs) and so are cardiopulmonary splanchnic nerves; the lower thoracic splanchnic nerves form the greater, lesser, and lowest splanchnic nerves and supply viscera below the level of the diaphragm, and so are abdominopelvic splanchnic nerves. (05 Mar 2000) |
| thoracic stomach | A condition in which part or all of the stomach is contained within the thorax; a variant of hiatal hernia. Trifid stomach, a condition in which the stomach is divided by two constrictions into three pouches. Wallet stomach, a form of dilated stomach in which there is a general bag like distention, the antrum and fundus being indistinguishable. Water-trap stomach, a ptotic and dilated stomach, having a relatively high (though normally placed) pyloric outlet which is held up by the gastrohepatic ligament. Synonym: drain-trap stomach.

| thoracic surgeon | <specialist> A physician specialist expert in the surgical treatment of diseases of the chest, heart and lungs. (27 Sep 1997) |
| thoracic surgery | <study> A branch of medicine dealing with the use of surgery to treat diseases of the chest and lungs. (09 Oct 1997) |

| thoracic veins | See: internal thoracic vein, lateral thoracic vein. (05 Mar 2000) |
| thoracic vertebrae | The segments of the vertebral column, usually twelve, which articulate with ribs to form part of the thoracic cage. Synonym: vertebrae thoracicae. (05 Mar 2000) |
| thoracic wall | In respiratory physiology, the total system of structures outside the lungs that move as a part of breathing; it includes the rib cage, diaphragm, abdominal wall, and abdominal contents. Synonym: thoracic wall. (05 Mar 2000) |
| true neurogenic thoracic outlet syndrome | <syndrome> Very chronic axon loss brachial plexopathy, caused by compromise of the lower trunk fibres by a congenital band extending from a rudimentary cervical rib to the first thoracic rib; rare disorder, found mostly in young to middle-aged women, that presents with unilateral hand wasting and weakness, particularly involving the lateral thenar eminence; sometimes accompanied by intermittent discomfort along the medial forearm and hand. Synonym: cervical rib and band syndrome, classic cervical rib syndrome. (05 Mar 2000) |
| upper thoracic splanchnic nerves | Part of the cardiopulmonary splanchnic nerves from the second to fifth segments of the thoracic sympathetic trunk that pass medially and anteriorly to enter the cardiac plexus; they convey postsynaptic sympathetic fibres to, and visceral afferent (pain) fibres from, the heart. Synonym: nervi cardiaci thoracici, upper thoracic splanchnic nerves. (05 Mar 2000) |
| lateral anterior thoracic nerve | <anatomy, nerve> A nerve that arises from the lateral cord of the brachial plexus usually passing medial to pectoralis minor to supply the sternoclavicular head of pectoralis major. Synonym: nervus pectoralis lateralis, lateral anterior thoracic nerve. (05 Mar 2000) |
| 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) |
