(From corpus,a body). See Cerebrum.

Corpora cavernosa penis, called also nervea spongiosa. The two bodies, thus named, rise by two distinct crura from the lower part of the ossa pubis; after which they join, and are continued to the glans. They are separated by a septum, disposed like the teeth of a comb, so that any fluid forced into one distends the other. The two crura are connected to the symphysis of the os pubis by the ligamentum suspensorium, which proceeds from the cartilage, and is diffused upon the sheaths of the corpora cavernosa. Towards the upper extremity of the corpora cavernosa are several white ligaments, which seem to be placed there to hinder the penis from being too much distended. In the axis between each corpuscavernosum an artery and a vein run. which enter near the union of the crura, and ramify throughout the spongy substance.

Corpora fimbriata. A border on the edge of the fornix in the brain. See Fornix.

Corpora lobosa. See Renes.

Corpora olivaria. Two eminences on the medulla oblongata.

Corpora pyramidalia. Two other eminences on the medulla oblongata, near the corpora olivaria, confounded by Willis with the latter.

Corpora striata. Two prominences in the lateral ventricles of the brain, in which we meet with a great number of white and ash coloured lines alternately disposed, but these are only the transverse section of the medullary and cortical laminae mixed together. See Cerebrum.
