| Meissner's corpuscle | One of numerous oval bodies found in the papillae of the skin, especially those of the fingers and toes; they consist of a connective tissue capsule in which the axon fibrils terminate around and between a pile of wedge-shaped epithelioid cells. Synonym: corpusculum tactus, Meissner's corpuscle, oval corpuscle, touch corpuscle. (05 Mar 2000) |

| reticulated corpuscle | <haematology> Immature red blood cells normally restricted to the bone marrow and present in the blood stream in very low numbers (0.2-2%). An increase in numbers indicates increased proliferation in the bone marrow, for example following chemotherapy. (09 Oct 1997) |
| Golgi corpuscle | <cell biology> An encapsulated sensory nerve ending similar to a pacinian corpuscle but simpler in structure. Tactile corpuscles found in the subcutaneous tissue of the fingertips, resembling pacinian corpuscles, but possessing fewer lamellae and a relatively larger cone, and having the contained fibres more extensively branched. (12 Mar 2000) |
| Golgi-Mazzoni corpuscle | <cell biology> An encapsulated sensory nerve ending similar to a pacinian corpuscle but simpler in structure. Tactile corpuscles found in the subcutaneous tissue of the fingertips, resembling pacinian corpuscles, but possessing fewer lamellae and a relatively larger cone, and having the contained fibres more extensively branched. (12 Mar 2000) |
| Merkel's corpuscle | A specialised tactile sensory nerve ending in the epidermis, characterised by a terminal cuplike expansion of an intraepidermal axon in contact with the base of a single modified keratinocyte. Synonym: meniscus tactus, Merkel's corpuscle, Merkel's tactile cell, Merkel's tactile disk, tactile disk. (05 Mar 2000) |
| Grandry's corpuscle | General sensory endings in the beak, mouth, and tongue of birds; similar to Merkel's corpuscle's. (05 Mar 2000) |
| pessary corpuscle | An elongated red blood cell with haemoglobin concentrated in the peripheral portion. (05 Mar 2000) |
| phantom corpuscle | A hypochromic, crescent-shaped erythrocyte, probably resulting from artifactual rupture of a red cell with loss of haemoglobin. Synonym: achromacyte, achromatocyte, ghost corpuscle, phantom corpuscle, Ponfick's shadow, shadow corpuscle, shadow, Traube's corpuscle. Origin: G. A-priv. + chroma, colour, + kytos, hollow (cell) (05 Mar 2000) |
| Mexican hat corpuscle | An erythrocyte in target cell anaemia, with a dark centre surrounded by a light band that again is encircled by a darker ring; it thus resembles a shooting target; such cell's also appear after splenectomy. A cell lysed by cytotoxic T lymphocytes, as in graft rejection. Synonym: Mexican hat cell. (05 Mar 2000) |
| chyle corpuscle | A cell of the same appearance as a leukocyte, present in chyle. (05 Mar 2000) |
| milk corpuscle | One of the fat droplets in milk. (05 Mar 2000) |
| molluscum corpuscle | A disticntive intracellular spherical body in the lesions of molluscum contagiosum caused by a member of the family Poxviridae; it consists of degenerated cytoplasm and the virus. Synonym: molluscum corpuscle. (05 Mar 2000) |
| colloid corpuscle | One of a number of small ovoid or rounded, sometimes laminated, bodies resembling a grain of starch and found in nervous tissue, in the prostate, and in pulmonary alveoli; of little pathological significance, and apparently derived from degenerated cells or proteinaceous secretions. Synonym: amniotic corpuscle, amylaceous corpuscle, amyloid corpuscle, colloid corpuscle. (05 Mar 2000) |
| colostrum corpuscle | One of numerous bodies present in the colostrum, supposed to be modified leukocytes containing fat droplets. Synonym: Donne's corpuscle, galactoblast. (05 Mar 2000) |
| white corpuscle | Any type of leukocyte. (05 Mar 2000) |
