| runner's condition | <orthopaedics> A condition where the knee cap (patella) rubs on the surface of the femur rather than following its normal tracking over the knee joint. This condition is brought about by stress or overuse (for example runners). Running on hills or incline surfaces can exacerbate this problem. Symptoms include knee pain, just under the knee cap after running, progressing to knee pain at rest. Treatment includes rest and stretching exercises for the quadriceps and hamstring muscles. Strengthening the medial (inner) head of the quadriceps (along the inner thigh) will help pull the knee cap medially and correct the problem. (17 Dec 1997) |

| condition | A mode or state of being, the state of being fit: the physical status of the body as a whole or of one of its parts usually used to indicate abnormality. (18 Nov 1997) |
| sine condition | <microscopy> The design of a lens must fulfill this condition, described by Abbe, if the image is to be aplanatic. It states that the ratio of the sines of the angles of the incident and refracted rays to the axis must be constant, this constant is equal to the inverse of the magnification of the image.

| stoichiometric condition | That condition at which the proportion of the air-to-fuel is such that all combustible products will be completely burned with no oxygen remaining in the combustion air. (05 Dec 1998) |
| desired future condition | A vision of the desired future state of a specific area. A description of land and resource conditions expected to result if management goals and objectives are achieved. (05 Dec 1998) |
| disturbed condition | <ecology> Refers to areas in which indicators of one or more characteristics (vegetation, soil and/or hydrology) have been sufficiently altered by man's activities or natural events so as to make it more difficult to recognise whether or not the wetland identification criteria are met.

| fibrocystic condition of the breast | A benign disease common in women of the third, fourth, and fifth decades characterised by formation, in one or both breasts, of small cysts containing fluid which may appear as blue dome cysts; associated with stromal fibrosis and with variable degrees of intraductal epithelial hyperplasia and sclerosing adenosis. Synonym: cystic hyperplasia of the breast. (05 Mar 2000) |
| abdominal external oblique muscle | <anatomy, muscle> Origin, fifth to twelfth ribs; insertion, anterior half of lateral lip of iliac crest, inguinal ligament, and anterior layer of the rectus sheath; action, diminishes capacity of abdomen, draws thorax downward; nerve supply, thoracoabdominal nerves. Synonym: musculus obliquus externus abdominis, abdominal external oblique muscle. (05 Mar 2000) |
| ambiguous external genitalia | External genitalia not clearly of either sex; most commonly designates external genitalia that are incompletely masculinised. (05 Mar 2000) |
| anterior scrotal branch of external pudendal artery | <anatomy, artery> Distribution, skin of anterior scrotum; anastomoses, posterior scrotal branches from internal pudendal artery. Synonym: rami scrotales anteriores arteriae pudendae externae. (05 Mar 2000) |
| aponeurosis of external abdominal oblique muscle | <anatomy> Broad, flat tendinous portion of the external abdominal oblique muscle. The fleshy fibres of the muscle end in the aponeurosis along a line descending vertically from the costochondral joint of the ninth rib then turning laterally just below the level of the umbilicus toward the anterior superior iliac spine. The fibres of the aponeurosis run medially and inferiorly, contributing to the anterior wall of the sheath of the rectus abdominis muscle and decussating with those of the contralateral aponeurosis at the median linea alba. Inferomedially, the aponeurosis is attached to the upper border of the pubic symphysis, the pubic crest and pubic tubercle. Between the anterior superior iliac spine and the pubic tubercle, it is thickened and turned under, forming the inguinal ligaments. The portion of the aponeurosis attached to the pubic bone forms the superficial inguinal ring by splitting into medial and lateral crura. See: external spermatic fascia, inguinal ligament, lacunar ligament, pectineal ligament, reflected inguinal ligament, superficial inguinal ring, rectus sheath. (05 Mar 2000) |
| bony part of external acoustic meatus | The medial two-thirds of the external acoustic meatus which is formed as the tympanic plate of the temporal bone develops; it extends approximately 16 mm. From its junction with the cartilaginous part to the tympanic membrane. (05 Mar 2000) |
| carotid artery, external | Branch of the common carotid artery which supplies the exterior of the head, the face, and the greater part of the neck. (12 Dec 1998) |
| cartilaginous part of external acoustic meatus | The lateral third of the external acoustic meatus which is continuous with the auricular cartilage and attached to the circumference of the bony part. (05 Mar 2000) |
| chronic progressive external ophthalmoplegia | A specific type of slowly worsening weakness of the ocular muscles, usually associated with a pigmentary retinopathy. See: Kearns-Sayre syndrome, oculopharyngeal dystrophy. Synonym: ocular myopathy. (05 Mar 2000) |
