corpus genicula´tum see geniculate bodies, lateral, and geniculate bodies, medial.
corpus hemorrha´gicum
1. an ovarian follicle containing blood.
2. a corpus luteum containing a blood clot.
3. a blood clot formed in the cavity left by rupture of a graafian follicle.

cor·pus cal·lo·sum

[TA]
the great commissural plate of nerve fibers interconnecting the cortical hemispheres (with the exception of most of the temporal lobes, which are interconnected by the anterior commissure). Lying at the floor of the longitudinal fissure, and covered on each side by the cingulate gyrus, it is arched from behind forward and is thicker at each extremity (splenium [TA] and genu [TA]) but thinner in its long central portion (truncus [TA]); it curves back underneath itself at the genu to form the rostrum [TA] of the corpus callosum.

corpus callosum

(kə-lō′səm)
n. pl. corpora callosa (kə-lō′sə)
The arched bridge of nervous tissue that connects the two cerebral hemispheres, allowing communication between the right and left sides of the brain.

cor·pus cal·lo·sum

(kōr'pŭs ka-lō'sŭm) [TA]
The great commissural plate of nerve fibers interconnecting the cortical hemispheres (with the exception of most of the temporal lobes, which are interconnected by the anterior commissure). Lying at the floor of the longitudinal fissure, and covered on each side by the cingulate gyrus, it is arched from behind forward and is thick at each extremity (splenium and genu) but thinner in its long central portion (truncus); it curves back underneath itself at the genu to form the rostrum of the corpus callosum.

corpus callosum

The wide curved band of nerve fibres (white matter) that connects the two cerebral hemispheres.

corpus callosum

a band of nervous tissue connecting the cerebral hemispheres in the higher mammals.
