cavernosus

The cavernous plexus (plexus cavernosus) is situated below and medial to that part of the internal carotid artery which is placed by the side of the sella turcica in the cavernous sinus, and is formed chiefly by the medial division of the internal carotid nerve.

The cavernous sinuses (sinus cavernosus) (Figs. 570, 571) are so named because they present a reticulated structure, due to their being traversed by numerous interlacing filaments.

The greater cavernous nerve (n. cavernosus penis major; large cavernous plexus) passes forward along the dorsum of the penis, joins with the dorsal nerve of the penis, and is distributed to the corpora cavernosa.

Under the influence of the stimulation furnished by the contact and friction of the vagina, this process is effectively carried out, mainly by the rhythmic contractions of the bulbo-cavernosus muscle, and the semen is emitted in a jet which may be ejaculated to a distance varying from a few centimeters to a meter or more.

[106] Onanoff (Paris Société de Biologie, May 3, 1890) proposed the name of bulbo-cavernous reflex for the smart contraction of the ischio-and bulbo-cavernosus muscles (erector penis and accelerator urinæ) produced by mechanical excitation of the glans.

This vaginal contraction which in women only becomes well marked just before detumescence, and is due mainly to the action of the sphincter cunni (analogous to the bulbo-cavernosus in the male), is only a part of the localized muscular process.

The decisive moment in the production of the instinctive and involuntary orgasm occurs when, under the influence of the stimulus applied to the penis by friction with the vagina, the tension of the seminal fluid poured into the urethra arouses the ejaculatory center in the spinal cord and the bulbo-cavernosus muscle surrounding the urethra responsively contracts in rhythmic spasms.

The condition wherein the penis is flaccid, the arteries heading to the sinus cavernosus remain compressed and hence reduced the blood flow pace.

The male reproductive organ, penis is made up of chambers known as corpus cavernosum and corpus spongiosum those are carried thoroughly with capillary tubing and blood vessels called as sinus cavernosus, closed in trabeculate muscular tissues.
