accessory corpus lutea

the corpora lutea which develop during early pregnancy in the mare and which follow the subsidence of the first corpus luteum.

corpus albicans, corpora albicantia

white fibrous tissue that replaces the regressing corpus luteum in the ovary in the latter half of pregnancy.

corpus amygdaloideum

a small mass of subcortical gray matter within the tip of the temporal lobe, anterior to the temporal horn of the lateral ventricle of the brain; it is part of the limbic system.

corpus amylacea

small hyaline masses of degenerate cells found in the prostate, thyroid, neuroglia and milk where they may be sufficient in a cow to block the teat sinus. They are formed by stasis of milk flow in a duct and inspissation of the fluids. Subsequently they may become detached and find their way to the teat.

corpus atreticum

scar in the ovary produced by atresia of a follicle when late in its development.

corpus callosum

an arched mass of white matter in the depths of the longitudinal fissure of the brain, and made up of transverse fibers connecting the cerebral hemispheres.

corpus callosum agenesis

all or part of the corpus may be absent and there may be additional associated defects.

corpus cavernosum clitoridis

one of the pair of erectile bodies of the clitoris.

corpus cavernosum penis

either of the two columns of erectile tissue forming the body of the penis or clitoris. See also corpus cavernosum penis.

corpus cavernosum penis rupture

common in bulls occurring during mating; commonly at the distal bend of the sigmoid flexure; result in hematoma and subsequent adhesions with inability to protrude the penis properly or angulation of the penis.

corpus cavernosum urethrae

see corpus spongiosum penis.

corpus fimbriatum

a band of white matter bordering the lateral edge of the temporal cornu of the lateral ventricle of the brain.

corpus geniculatum

see geniculate body lateral, and geniculate body medial.

corpus hemorrhagicum

1. an ovarian follicle, especially one freshly ruptured, containing blood.

2. a corpus luteum containing a blood clot.

corpus luteum

a progesterone-secreting yellow glandular mass in the ovary formed from the wall of an ovarian follicle that has matured and discharged its ovum. See also ovulation. In most animals that do not conceive the corpus luteum regresses quickly and a new follicle develops. The corpus luteum may be retained when there is uterine pathology which mimics pregnancy; no new follicle develops and the cow fails to come into heat. Called also retained corpus luteum. A similar clinical picture is observed with cystic corpora lutea.

corpus spongiosum penis

see corpus spongiosum penis.

corpus striatum

a subcortical mass of gray and white substance in front of and lateral to the thalamus in each cerebral hemisphere.
