title: Corpus cavernosum of clitoris text: Corpus cavernosum of clitoris The corpus cavernosum of clitoris is one of a pair of sponge-like regions of erectile tissue which contain most of the blood in the clitoris during clitoral erection. This is homologous to the corpus cavernosum penis in the male; the body of the clitoris contains erectile tissue in a pair of "corpora cavernosa" (literally "cave-like bodies"), with a recognizably similar structure. The two corpora cavernosa are expandable erectile tissues which fill with blood during clitoral erection. These formations are made of a sponge-like tissue containing irregular blood-filled spaces lined by endothelium and separated by connective tissue title: Corpus cavernosum of clitoris text: septa. United together along their medial surfaces by an incomplete fibrous pectiniform septum; each corpus is connected to the rami of the pubis and ischium by a clitoral crus. The female anatomy has two vestibular bulbs beneath the skin of the labia minora (at the entrance to the vagina), which expand at the same time as the glans clitoridis to cap the ends of the corpora cavernosa. This is homologous with the corpus spongiosum of the male anatomy. In some circumstances, release of nitric oxide precedes relaxation of the clitoral cavernosal artery and nearby muscle, in a process similar to title: Corpora arenacea text: Corpora arenacea Corpora arenacea (or brain sand or acervuli or corpus arenaceum) are calcified structures in the pineal gland and other areas of the brain such as the choroid plexus. Older organisms have numerous corpora arenacea, whose function, if any, is unknown. Concentrations of "brain sand" increase with age, so the pineal gland becomes increasingly visible on X-rays over time, usually by the third or fourth decade. They are sometimes used as anatomical landmarks in radiological examinations. Chemical analysis shows that they are composed of calcium phosphate (later characterized as hydroxyapatite), calcium carbonate, magnesium phosphate, and ammonium phosphate. Recently, calcite title: Corpus cavernosum penis text: Corpus cavernosum penis A corpus cavernosum penis (singular) (cavernous body of the penis) is one of a pair of sponge-like regions of erectile tissue, the corpora cavernosa (plural) (cavernous bodies), which contain most of the blood in the penis during an erection. Such a corpus is homologous to the corpus cavernosum clitoridis in the female; the body of the clitoris contains erectile tissue in a pair of corpora cavernosa (literally "cave-like bodies") with a recognisably similar structure. The two corpora cavernosa and corpus spongiosum (also known as the "corpus cavernosum urethrae" in older texts and in the adjacent diagram) are title: Crus of clitoris text: Crus of clitoris The clitoral crura (singular: clitoral crus) are two erectile tissue structures, which together form a V-shape. "Crus" is a Latin word that means "leg". Each "leg" of the "V" converges on the clitoral body. At each divergent point is a corpus cavernosum of clitoris. The crura are attached to the pubic arch, and are adjacent to the vestibular bulbs. The crura flank the urethra, urethral sponge, and vagina and extend back toward the pubis. Each clitoral crus connects to the rami of the pubis and the ischium. During sexual arousal, the crura become engorged with blood, as
