| proximal centriole | The centriole that lies in a depression in the wall of the posterior portion of the nucleus of the developing spermatozoon. Synonym: anterior centriole. (05 Mar 2000) |
| proximal contact | Proximate contact, the area where the surfaces of two adjacent teeth in the same arch touch. Contact with reality, correctly interpreting external phenomena in relation to the norms of one's social or cultural milieu. Working contacts, working or occlusion; contact's of teeth made on the side of the occlusion toward which the mandible has been moved. Synonym: working bite, working occlusion. (05 Mar 2000) |

| proximal radioulnar articulation | The pivot synovial joint between the head of the radius and the ring formed by the radial notch of the ulna and the annular ligament. Synonym: articulatio radioulnaris proximalis, proximal radioulnar articulation, superior radioulnar joint. (05 Mar 2000) |
| proximal radioulnar joint | The pivot synovial joint between the head of the radius and the ring formed by the radial notch of the ulna and the annular ligament. Synonym: articulatio radioulnaris proximalis, proximal radioulnar articulation, superior radioulnar joint. (05 Mar 2000) |

| proximal spiral septum | See: spiral septum. (05 Mar 2000) |
| proximal tibiofibular joint | The plane synovial joint between the lateral condyle of the tibia and the head of the fibula. Synonym: articulatio tibiofibularis, superior tibial articulation, superior tibiofibular joint, tibiofibular articulation. (05 Mar 2000) |
| proximal urethral sphincter | The complete collar of smooth muscle cells of the neck of the urinary bladder which extend distally to surround the preprostatic sportion of the male urethra. There is not a comparable structure in the neck of the femoral bladder; the internal urethral sphincter may exist to prevent reflux of semen into bladder. Synonym: annulus urethralis, internal urethral sphincter, musculus sphincter vesicae, preprostate urethral sphincter, proximal urethral sphincter, sphincter muscle of urinary bladder. (05 Mar 2000) |
| acute kidney failure | <nephrology> A sudden decline in renal function may be triggered by a number of acute disease processes. Examples include sepsis (infection), shock, trauma, kidney stones, kidney infection, drug toxicity (aspirin or lithium), poisons or toxins (drug abuse) or after injection with an iodinated contrast dye (adverse effect). Chronic renal failure represents a slow decline in kidney function over time. Chronic renal failure may be caused by a number of disorders which include long-standing hypertension, diabetes, congestive heart failure, lupus or sickle cell anaemia. Both forms of renal failure result in a life-threatening metabolic derangement. (27 Sep 1997) |
| acute kidney transplant rejection | <radiology> Findings on ultrasound: globular enlargment of the kidney, swelling and hypoechogenicity of the medullary pyramids, indistinct cortico-medullary junction, foci in the renal cortex (12 Dec 1998) |
| african green monkey kidney cell | <cell culture> Cells taken from the kidneys of the African green monkey Cercopithecus aethiops sabaeus and used to grow certain viruses like poliovirus. (05 Feb 1998) |
| amyloid kidney | A kidney in which amyloidosis has occurred, usually in association with some chronic illness such as multiple myeloma, tuberculosis, osteomyelitis, or other chronic suppurative inflammation; such kidney's are moderately enlarged and grossly manifest a waxy appearance, with amyloid deposited beneath the endothelium in the glomerular loops and in the arterioles, apparently beginning as foci of thickening of the basement membranes. Synonym: waxy kidney. (05 Mar 2000) |
