| epilepsy, complex partial | Epileptic seizures that are episodic changes in behaviour in which an individual loses conscious contact with the environment. The onset of such seizures involves any of a variety of auras: deja-vu, an unusual smell, a sudden intense emotional feeling, a sensory illusion such as micropsia (objects growing smaller) or macropsia (objects growing larger), or other sensory hallucination. There may be a cessation of activity with some minor motor activity such as lip smacking, walking aimlessly, or other automatisms. The seizures may also be accompanied by the unconscious performance of highly skilled activities such as driving a car. When the seizure ends, the individual is amnesic for events that took place during the seizure and may take minutes or hours to recover fully to consciousness. (12 Dec 1998) |
| triple symptom complex | <syndrome> A multisystem, chronic recurrent disease characterised by ulceration in the mouth and genitalia, iritis, uveitis, arthritis and thrombophlebitis. Often treated with immunosuppressive therapy (corticosteroids, chlorambucil). (27 Sep 1997) |
| equiphasic complex | A diphasic complex whose positive and negative deflections are approximately equal. Synonym: equiphasic complex. (05 Mar 2000) |
| j-g complex | A complex consisting of the juxtaglomerular cells, which are modified smooth muscle cells in the wall of the afferent glomerular arteriole and sometimes also the efferent arteriole; extraglomerular mesangium lacis cells, which are located in the angle between the afferent and efferent glomerular arterioles; the macula densa of the distal convoluted tubule; and granular epithelial peripolar cells located at the angle of reflection of the parietal to the visceral capsule of the renal corpuscle; believed to provide some feedback control of extracellular fluid volume and glomerular filtration rate. Synonym: j-g complex, juxtaglomerular apparatus. (05 Mar 2000) |

| junctional complex | The attachment zone between epithelial cells, typically consisting of the zonula occludens, the zonula adherens, and the macula adherens (desmosome). (05 Mar 2000) |
| juxtaglomerular complex | A complex consisting of the juxtaglomerular cells, which are modified smooth muscle cells in the wall of the afferent glomerular arteriole and sometimes also the efferent arteriole; extraglomerular mesangium lacis cells, which are located in the angle between the afferent and efferent glomerular arterioles; the macula densa of the distal convoluted tubule; and granular epithelial peripolar cells located at the angle of reflection of the parietal to the visceral capsule of the renal corpuscle; believed to provide some feedback control of extracellular fluid volume and glomerular filtration rate.

| father complex | Female counterpart of the Oedipus complex in the male; a term used to describe unresolved conflicts during childhood development toward the father which subsequently influence a woman's relationships with men. Synonym: father complex. Origin: Electra, daughter of Agamemnon (05 Mar 2000) |
| fatty acid synthase complex | The multienzyme complex that catalyses the formation of palmitate from acetylcoenzyme A, malonylcoenzyme A, and NADPH. (05 Mar 2000) |
| fatty acid synthetase complex | <enzyme> Registry number: EC 6.- (12 Dec 1998) |
| feline leukaemia-sarcoma virus complex | Viruses from cats that induce transmissible leukaemia or transmissible fibrosarcoma in kittens. (05 Mar 2000) |
| femininity complex | In psychoanalysis, the unconscious fear, in boys and men, of castration at the hands of the mother with resultant identification with the aggressor and envious desire for breasts and vagina. (05 Mar 2000) |
