| 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) |
| peripheral vision | Vision resulting from retinal stimulation beyond the macula. Synonym: indirect vision. (05 Mar 2000) |
| neuroectodermal tumour, peripheral | A heterogeneous group of malignant neoplasms arising in either supportive structures or neuronal tissue. They occur in adolescents and young adults. This tumour shares a number of characteristics with ewing's sarcoma: it is highly cellular and consists of a monotonous pattern of primitive-appearing round cells. The chest wall is the most common site but the trunk, abdomen, and pelvis are other primary sites. (12 Dec 1998) |
| total 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) |
| lymphoma, T-cell, peripheral | A group of malignant lymphomas thought to derive from peripheral T-lymphocytes in lymph nodes and other nonlymphoid sites. They include a broad spectrum of lymphocyte morphology, but in all instances express T-cell markers admixed with epithelioid histiocytes, plasma cells, and eosinophils. Although markedly similar to large-cell immunoblastic lymphoma (lymphoma, large-cell, immunoblastic), this group's unique features warrant separate treatment. (12 Dec 1998) |
