| greater sciatic notch | The deep indentation in the posterior border of the hip bone at the point of union of the ilium and ischium. Synonym: incisura ischiadica major, iliosciatic notch, sacrosciatic notch. (05 Mar 2000) |
| great sciatic nerve | <anatomy, nerve> A nerve which originates in the lumbar and sacral spinal cord (l4 to s3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the tibial nerve and the peroneal nerve. (12 Dec 1998) |
| companion artery to sciatic nerve | <anatomy, nerve> Origin, inferior gluteal; distribution, sciatic nerve; anastomoses, branches of profunda femoris. Synonym: arteria comitans nervi ischiadici, companion artery to sciatic nerve. (05 Mar 2000) |
| sciatic | <anatomy> Of or pertaining to the hip; in the region of, or affecting, the hip; ischial; ischiatic; as, the sciatic nerve, sciatic pains. Origin: F. Sciatique, LL. Sciaticus, from L. Inschiadicus, Gr. See Ischiadic. <medicine> Sciatica. Origin: Cf. F. Sciatique. Source: Websters Dictionary (01 Mar 1998) |
| sciatic foramen | Either of two foramina formed by the sacrospinous and sacrotuberous ligaments crossing the sciatic notches of the hip bone: greater sciatic foramen and lesser sciatic foramen. Synonym: foramen ischiadicum. (05 Mar 2000) |
| sciatic hernia | Protrusion of intestine through the great sacrosciatic foramen. Synonym: gluteal hernia, ischiocele. (05 Mar 2000) |
| sciatic nerve | <anatomy, nerve> A nerve which originates in the lumbar and sacral spinal cord (l4 to s3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the tibial nerve and the peroneal nerve. (12 Dec 1998) |
| sciatic neuralgia | A syndrome characterised by pain radiating from the back into the buttock and into the lower extremity along its posterior or lateral aspect and most commonly caused by prolapse of the intervertebral disk, the term is also used to refer to pain anywhere along the course of the sciatic nerve. (18 Nov 1997) |
| sciatic neuritis | A syndrome characterised by pain radiating from the back into the buttock and into the lower extremity along its posterior or lateral aspect and most commonly caused by prolapse of the intervertebral disk, the term is also used to refer to pain anywhere along the course of the sciatic nerve. (18 Nov 1997) |
| sciatic plexus | Formed by the fourth and fifth lumbar (lumbosacral trunk) and first, second, and third sacral nerves; it lies on the inner surface of the posterior wall of the pelvis usually embedded in the piriformis muscle; its nerves supply the lower limbs, its major product being the sciatic nerve. Synonym: plexus sacralis, ischiadic plexus, sciatic plexus. (05 Mar 2000) |
| sciatic scoliosis | Scoliosis caused by asymmetric spasm of spinal muscles usually associated with sciatica, usually presenting as a list toward one side. (05 Mar 2000) |
| sciatic spine | A pointed process from the posterior border of the ischium on a level with the lower border of the acetabulum; gives attachment to the sacrospinous ligament; the pudendal nerve passes dorsal to the ischial spine, which is palpable per vagina or rectum, and thus is used as a target for the needle-tip in administering a pudendal nerve block. Synonym: spina ischiadica, ischiadic spine, sciatic spine. (05 Mar 2000) |
| small sciatic nerve | <anatomy, nerve> Arises from the first three sacral nerves, supplies the skin of the posterior surface of the thigh and of the popliteal region (S1 and S2 component); it gives off a perineal branch (S3 component) that passes to the lateral aspect of the scrotum or labia majora. Synonym: nervus cutaneus femoris posterior, posterior cutaneous nerve of thigh, small sciatic nerve. (05 Mar 2000) |
| lesser sciatic notch | The notch in the posterior border of the ischium below the ischial spine. Synonym: incisura ischiadica minor. (05 Mar 2000) |
