| peripheral facial paralysis | A condition that involves the facial nerve (VII cranial nerve) and results in the paralysis of one side of the face. Bell's (facial nerve palsy) can be differentiated from a central (stroke) deficit by the inability to raise the eyebrow on the affected side. (27 Sep 1997) |

| peripheral glare | Glare occurring when the surrounding brightness is greater than the brightness of the object of attention. (05 Mar 2000) |
| peripheral lymphoid tissue | Secondary lymphoid tissue, not necessarily located peripherally. See: lymphoid tissue. (18 Nov 1997) |
| peripheral membrane protein | <protein> Membrane proteins that are bound to the surface of the membrane and not integrated into the hydrophobic region. Usually soluble and were originally thought to bind to integral proteins by ionic and other weak forces (and could therefore be removed by high ionic strength, for example). However, it is now clear that some peripheral membrane proteins are covalently linked to molecules that are part of the membrane bilayer (see acylated proteins and glypiation) and that there are others that fit the original definition but are perhps more appropriately considered proteins of the cytoskeleton (e.g. Band 4.1 and spectrin) or extracellular matrix (e.g. Fibronectin). (18 Nov 1997) |
| peripheral nerves | The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium. (12 Dec 1998) |
| peripheral neuropathy | <neurology> Injury to the nerves that supply sensation to the arms and legs. Origin: Gr. Pathos = disease (16 Dec 1997) |
| peripheral ossifying fibroma | A reactive focal gingival overgrowth derived histogenetically from cells of the periodontal ligament and usually developing in response to local irritants (plaque and calculus) on associated teeth; consists microscopically of a hyperplastic cellular fibrous stroma supporting deposits of bone, cementum, or dystrophic calcification. (05 Mar 2000) |
| peripheral protein | <protein> A water-soluble protein that is loosely bound (by hydrogen bonds orelectrostatic forces) to a membrane. (09 Oct 1997) |
| peripheral proteins | Pathways that can be easily removed from a biomembrane (e.g., by altering the pH or the ionic strength). Synonym: extrinsic proteins. (05 Mar 2000) |
| peripheral resistance | The total resistance to flow of blood in the systemic circuit; the quotient produced by dividing the mean arterial pressure by the cardiac minute-volume. Synonym: peripheral resistance. (05 Mar 2000) |
| peripheral scotoma | A scotoma outside of the central 30 degrees of the visual field. (05 Mar 2000) |
| peripheral seal | border seal |
| peripheral tabes | A syndrome having the characteristics of tabetic neurosyphilis but not due to syphilis. Synonym: Leyden's ataxia, peripheral tabes, pseudoataxia. (05 Mar 2000) |
| peripheral vascular disease | A term used to describe progressive occlusive disease of the arteries that supply the extremities. Risk factors include atherosclerosis and diabetes. (27 Sep 1997) |
| peripheral vascular diseases | General or unspecified diseases of the blood vessels outside the heart. It is for diseases of the peripheral as opposed to the cardiac circulation. (12 Dec 1998) |
