| subcutaneous portion of external anal sphincter | pars subcutanea musculi sphincteri ani externi, subcutaneous portion of external anal sphincter |
| superficial part of external anal sphincter | superficial part of external anal sphincter |
| supra-anal | Above the anus. Synonym: superanal. (05 Mar 2000) |
| deep part of external anal sphincter | deep part of external anal sphincter |
| internal anal sphincter | <anatomy> A smooth muscle ring, formed by an increase of the circular fibres of the rectum, situated at the upper end of the anal canal, internal to the outer voluntary external anal sphincter. This sphincter is maximally-contracted when the rectal ampulla is at rest -empty or relaxed to accommodate a distending faecal mass. It is inhibited with filling of the ampulla, increased distension and peristalsis. Synonym: musculus sphincter ani internus, internal sphincter muscle of anus. (05 Mar 2000) |
| external anal sphincter | A fusiform ring of striated muscular fibres surrounding the anus, attached posteriorly to the coccyx and anteriorly to the central tendon of the perineum; it is subdivided, often indistinctly, into a subcutaneous part, a superficial part and a deep part for descriptive purposes. Synonym: musculus sphincter ani externus, external sphincter muscle of anus. (05 Mar 2000) |
| alcoholic hyaline bodies | Large, poorly defined accumulations of eosinophilic material in the cytoplasm of damaged hepatic cells in certain forms of cirrhosis and marked fatty change especially due to alcoholism. Synonym: alcoholic hyalin, alcoholic hyaline bodies. (05 Mar 2000) |
| Alder bodies | Granular inclusions in polymorphonuclear leukocytes; they take on a dark colour with Giemsa-Wright stain and react metachromatically with toluidine blue. See: Alder's anomaly. (05 Mar 2000) |
| amyloid bodies of the prostate | An obsolete term for small masses of colloid material often present in the tubules of the gland. See: corpus amylaceum. (05 Mar 2000) |
| aortic bodies | Small clusters of chemoreceptive and supporting cells located near the aortic arch, the pulmonary arteries, and the coronary arteries. The aortic bodies sense pH, carbon dioxide, and oxygen concentrations in the blood and participate in the control of respiration. (12 Dec 1998) |
| Arnold's bodies | Small portions or minute fragments of erythrocytes (sometimes mistaken for blood platelets), or small "ghosts" of erythrocytes. (05 Mar 2000) |
| asbestos bodies | Ferruginous body's with asbestos fibres as a core; a histologic hallmark of exposure to asbestos. (05 Mar 2000) |
| Aschoff bodies | <pathology> Small granulomas composed of macrophages, lymphocytes and multinucleate cells grouped around eosinophilic hyaline material derived from collagen. Characteristic of the myocarditis of rheumatic fever. (18 Nov 1997) |
| Auer bodies | Rod-shaped structures of uncertain nature in the cytoplasm of immature myeloid cells, especially myeloblasts, in acute myelocytic leukaemia; may be an abnormal form of lysosomes; they contain peroxidase and acid phosphatase, and stain red by azure-eosin stains. Synonym: Auer rods. (05 Mar 2000) |
