| congenital adrenal hyperplasia | <endocrinology> A genetic disorder present at birth characterised by a deficiency of the hormones aldosterone and cortisol and an overproduction of male sex hormones (androgens). In males this may manifest as enlarged penis, small testes and early development of masculine characteristics. In females features include ambiguous genitalia, failure to menstruate, deep voice and excessive hair. Origin: Gr. Plassein = to form (27 Sep 1997) |

| congenital virilizing adrenal hyperplasia | A series of inherited inborn errors of metabolism with hyperplasia of the adrenal cortex and overproduction of virilizing hormones. Most common forms are due to partial or complete 21-hydroxylase deficiency, leading to increased ACTH production by the pituitary, stimulating adrenal growth and function. Severe form is characterised by salt-losing state. (05 Mar 2000) |
| foetal adrenal cortex | An extensive area of the adrenal gland present in primates during foetal life and for a short period after birth; located between the definitive cortex and the medulla, it contains large steroid-secreting cells arranged in a reticular pattern; involution of this zone in humans is largely completed by three months after birth. Synonym: androgenic zone, foetal reticularis, foetal zone, provisional cortex. (05 Mar 2000) |

| anocutaneous line | The line between the simple columnar epithelium of the rectum and the stratified epithelium of the anal canal. Synonym: linea anocutanea, anocutaneous line, dentate line. (05 Mar 2000) |
| anterior axillary line | A vertical line extending inferiorly from the anterior axillary fold. Synonym: linea axillaris anterior, linea preaxillaris, preaxillary line. (05 Mar 2000) |
| anterior junction line | Radiographic projection of the mediastinal tissue septum between the upper lobes behind the sternum. (05 Mar 2000) |
| anterior median line | The line of intersection of the midsagittal plane with the anterior surface of the body. Synonym: linea mediana anterior. (05 Mar 2000) |
| arcuate line | An arching or bow-shaped line. See: arcuate line of ilium, arcuate line of rectus sheath. Synonym: linea arcuata. (05 Mar 2000) |

| arcuate line of rectus sheath | A crescentic line, not always clearly defined, which marks the lower limit of the posterior layer of the sheath of the rectus abdominis muscle. Synonym: linea arcuata vaginae musculi recti abdominis, Douglas' line, linea saemicircularis, saemicircular line. (05 Mar 2000) |
