| brachial plexus | A network of lower cervical and upper dorsal spinal nerves supplying the arm, forearm and hand. (27 Sep 1997) |
| brachial plexus neuropathy | A neurological disorder, of unknown cause, characterised by the sudden onset of severe pain, usually about the shoulder and often beginning at night, soon followed by weakness and wasting of various forequarter muscles, particularly shoulder girdle muscles; both sporadic and familial in occurrence with the former much more common; often preceded by some antecedent event, such as an upper respiratory infection, hospitalization, vaccination, or non-specific trauma; usually attributed to a brachial plexus lesion, because the nerve fibres involed are most often derived from the upper trunk, but actually multiple proximal mononeuropathies. Synonym: acute brachial radiculitis, brachial plexitis, brachial plexus neuropathy, Parsonage-Turner syndrome, shoulder-girdle syndrome. (05 Mar 2000) |
| cardiac plexus | A wide-meshed network of anastomosing cardiopulmonary and splanchnic nerves arising from the afferent and autonomic nerve fibres (sympathetic) and vagus (parasympathetic) nerves, surrounding the arch of the aorta, the pulmonary artery, and continuing to the atria, ventricles, and coronary vessels. Synonym: plexus cardiacus. (05 Mar 2000) |
| vaginal venous plexus | The plexus of veins that surrounds the vagina. Synonym: plexus venosus vaginalis. (05 Mar 2000) |
| rami dentales inferiores plexus dentalis inferioris | Branches passing from the inferior dental plexus to the roots of the teeth of the lower jaw. Synonym: rami dentales inferiores plexus dentalis inferioris. (05 Mar 2000) |
| rami dentales superiores plexus dentalis superioris | Branches passing from the superior dental plexus to the roots of the teeth of the upper jaw. Synonym: rami dentales superiores plexus dentalis superioris. (05 Mar 2000) |
| vascular plexus | A vascular network formed by frequent anastomoses between the blood vessels (arteries or veins) of a part. Synonym: plexus vasculosus. (05 Mar 2000) |
| pampiniform plexus | <anatomy> A plexus formed, in the male, by veins from the testicle and epididymis, consisting of eight or ten veins lying in front of the ductus deferens and forming part of the spermatic cord. In the female the ovarian veins form this plexus between the layers of the broad ligament; in the male it is part of the thermoregulatory system of the testis, helping to keep the testis at a constant temperature slightly lower than the other body temperature. Synonym: plexus pampiniformis. (21 Jun 2000) |
| rami gingivales inferiores plexus dentalis inferioris | Branches of inferior dental plexus to the gingiva of the lower jaw. Synonym: rami gingivales inferiores plexus dentalis inferioris. (05 Mar 2000) |
| rami gingivales superiores plexus dentalis superioris | Branches of superior dental plexus to gingiva of upper jaw. Synonym: rami gingivales superiores plexus dentalis superioris. (05 Mar 2000) |
| pancreatic plexus | The autonomic plexus that accompanies the pancreatic arteries. Synonym: plexus pancreaticus. (05 Mar 2000) |
| ramus tubarius plexus tympanici | Sensory branch of tympanic plexus (of glossopharyngeal nerve) to auditory tube. Synonym: ramus tubarius plexus tympanici. (05 Mar 2000) |
| mammary plexus | A lymphatic plexus, including the parasternal; (internal thoracic) lymph nodes, with their vessels, situated along the course of the internal thoracic veins. Synonym: mammary plexus, plexus mammarius. (05 Mar 2000) |
