| subclavian | <anatomy> Situated under the clavicle, or collar bone; as, the subclavian arteries. Origin: Pref. Sub- + L. Clavis a key. See Clavicle. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| subclavian catheter | <equipment> Small, flexible plastic tube inserted into the large vein above the heart, through which drugs and blood products can be given and blood samples withdrawn painlessly. Synonym: central line, Hickman catheter. (12 Jan 1998) |
| subclavian duct | 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) |
| subclavian groove | A groove on the inferior surface of the body of the clavicle to which is attached the subclavius muscle. Synonym: sulcus musculi subclavii, subclavian sulcus, sulcus subclavianus. (05 Mar 2000) |
| subclavian loop | A nerve cord connecting the middle cervical and stellate sympathetic ganglia, forming a loop around the subclavian artery. Synonym: subclavian loop, Vieussens' ansa, Vieussens' loop. (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) |
| subclavian muscle | <anatomy, muscle> Origin, first costal cartilage; insertion, inferior surface of acromial end of clavicle; action, fixes clavicle or elevates first rib; nerve supply, subclavian from brachial plexus. Synonym: musculus subclavius, subclavian muscle. (05 Mar 2000) |
| subclavian nerve | <anatomy, nerve> A branch from the superior trunk of the brachial plexus supplying the subclavius muscle. Synonym: nervus subclavius. (05 Mar 2000) |
| subclavian periarterial plexus | The autonomic plexus accompanying the artery of this name, formed by fibres from the stellate ganglion, and giving off secondary plexus's along the branches of the subclavian. Synonym: plexus subclavius, subclavian plexus. (05 Mar 2000) |
| subclavian plexus | The autonomic plexus accompanying the artery of this name, formed by fibres from the stellate ganglion, and giving off secondary plexus's along the branches of the subclavian. Synonym: plexus subclavius, subclavian plexus. (05 Mar 2000) |
| subclavian steal | Obstruction of the subclavian artery proximal to the origin of the vertebral artery; blood flow through the vertebral artery is reversed and the subclavian artery thus "steals" cerebral blood, causing symptoms of vertebrobasilar insufficiency (subclavian steal syndrome); manifest during vigorous use of an upper extremity. (05 Mar 2000) |
| subclavian steal syndrome | <syndrome> Aortic arch syndrome, also referred to by many as vertebral-basilar artery disease, carotid artery occlusive syndrome and subclavian steal syndrome is characterised by a constellation of signs and symptoms which occur secondary to abnormalities in the major arteries which extend off of the aortic arch. These abnormalities are structural and most often secondary to the effects of atherosclerosis, blood clots, trauma or a congenital abnormality. Symptoms of this condition include various neurologic symptoms, reduction in pulse and changes in blood pressure. (27 Sep 1997) |
| subclavian sulcus | A groove on the inferior surface of the body of the clavicle to which is attached the subclavius muscle. Synonym: sulcus musculi subclavii, subclavian sulcus, sulcus subclavianus. (05 Mar 2000) |
| subclavian triangle | The triangle bounded by the clavicle, the omohyoid muscle, and the sternocleidomastoid muscle; it contains the subclavian artery and vein. Synonym: fossa supraclavicularis major, trigonum omoclaviculare, greater supraclavicular fossa, omoclavicular triangle, subclavian triangle. (05 Mar 2000) |
| subclavian vein | <anatomy, vein> The continuation of the axillary vein which follows the subclavian artery and then joins the internal jugular vein to form the brachiocephalic vein. (12 Dec 1998) |
