| sacral tuberosity | A rough prominence on the lateral surface of the sacrum posterior to the auricular surface for attachment of posterior sacroiliac ligaments. Synonym: tuberositas sacralis. (05 Mar 2000) |

| sacral veins | See: lateral sacral veins, median sacral vein. (05 Mar 2000) |
| sacral vertebrae | The segments of the vertebral column, usually five in number, that fuse to form the sacrum. Synonym: vertebrae sacrales. (05 Mar 2000) |
| intermediate sacral crests | Crests formed by the fusion of articular processes of all the sacral vertebrae. Synonym: articular crests, cristae sacrales intermediae. (05 Mar 2000) |
| lateral sacral artery | <anatomy, artery> Usually one of two arteries which arise from the internal iliac artery or its branches; they supply muscles and skin in the neighborhood and send branches into the sacral canal, supplying radicular and spinal arteries, and continuing on to the skin and subcutaneous tissues overlying the sacrum. Synonym: arteria sacralis lateralis. (05 Mar 2000) |
| lateral sacral crests | Crests which are rough ridges lying lateral to the sacral foramina; they represent the fused transverse processes of sacral vertebrae. Synonym: cristae sacrales laterales. (05 Mar 2000) |
| lateral sacral veins | Several veins that receive the drainage of the sacral venous plexus and sacral intervertebral veins then accompany the corresponding artery and empty into the internal iliac vein on each side. Synonym: venae sacrales laterales. (05 Mar 2000) |
| anterior part of anterior commissure of brain | The anterior part of the anterior or rostral commissure of the brain. Synonym: pars anterior commissurae rostralis, pars anterior commissurae anterioris cerebri. (05 Mar 2000) |
| abdominal aortic plexus | <anatomy, neurology> An autonomic plexus surrounding the abdominal aorta, directly continuous with the thoracic aortic plexus above and continued inferior to the bifurcation of the aorta as the superior hypogastric plexus. Synonym: plexus aorticus abdominalis. (05 Mar 2000) |
| acromial plexus | A vascular network between the acromion and the skin of the shoulder, formed by anastomoses of the acromial branch of the suprascapular artery with the acromial branch of the thoracoacromial artery. Synonym: rete acromiale, acromial plexus. (05 Mar 2000) |
| annular plexus | A nerve plexus near the corneoscleral junction from which myelinated and unmyelinated nerves pass to the cornea. Synonym: plexus annularis. (05 Mar 2000) |
| aortic lymphatic plexus | A plexus of lymph nodes and connecting vessels lying along the lower portion of the abdominal aorta. Synonym: plexus aorticus. (05 Mar 2000) |
| ascending pharyngeal plexus | An autonomic plexus on the artery of the same name, formed of fibres from the superior cervical ganglion. Synonym: plexus pharyngeus ascendens. (05 Mar 2000) |
| Auerbach's plexus | One of two ganglionated neural networks which together form the enteric nervous system. The myenteric (auerbach's) plexus is located between the longitudinal and circular muscle layers of the gut. Its neurons project to the circular muscle, to other myenteric ganglia, to submucosal ganglia, or directly to the epithelium, and play an important role in regulating and patterning gut motility. (12 Dec 1998) |
| axillary plexus | A lymphatic plexus formed of the lymph nodes, with their afferent and efferent vessels, in the axilla. Synonym: plexus axillaris. (05 Mar 2000) |
