A corpus cavernosum penis (singular) (from Latin, characterised by "cavities/ hollows" [2] of the penis, pl.: corpora cavernosa) is one of a pair of sponge-like regions of erectile tissue, which contain most of the blood in the penis of several animals during an erection.
The cavernous nerves are post-ganglionic parasympathetic nerves that facilitate penile erection and clitoral erection. [1] They arise from cell bodies in the inferior hypogastric plexus where they receive the pre-ganglionic pelvic splanchnic nerves (S2-S4). In the penis, there are both lesser cavernous nerves and a greater cavernous nerve.
Venous leak is an inability to maintain an erection in the presence of sufficient arterial blood flow through the cavernosal arteries of the penis. [6] The defect lies in the excessive drainage of veins in the cavernosal tissue of the penis, which undermines normal erectile function.
Erectile tissue is tissue in the body with numerous vascular spaces, or cavernous tissue, that may become engorged with blood. [1] [2] However, tissue that is devoid of or otherwise lacking erectile tissue (such as the labia minora, vestibule, vagina and urethra) may also be described as engorging with blood, often with regard to sexual arousal.
Peyronie's disease is a connective tissue disorder involving the growth of fibrous plaques in the soft tissue of the penis. Specifically, scar tissue forms in the tunica albuginea, the thick sheath of tissue surrounding the corpora cavernosa, causing pain, abnormal curvature, erectile dysfunction, indentation, loss of girth and shortening. [2] [3]
The body of the penis is suspended from the pubic symphysis. [7] It has two surfaces; the dorsal and the ventral or urethral.The penile raphe runs on its ventral surface.. The body is surrounded by a bi-layered model of tunica albuginea in which a distal ligament buttresses the glans penis and plays an integral role to the penile fibroskeleton, and the structure is called "os analog", a term ...
The human penis cannot be withdrawn into the groin, and it is larger than average in the animal kingdom in proportion to body mass. The human penis is reciprocating from a cotton soft to a bony rigidity resulting from penile arterial flow varied between 2–3 to 60–80 mL/Min implies the most ideal milieu to apply Pascal's law in the entire ...
The two crura of penis (one crus on each side) constitute the root of penis along with the bulb of penis. The two crura flank the bulb – one to each side of the bulb. Each crus is attached at the angle between the perineal membrane and ischiopubic ramus. The deep artery of the penis enters the anterior portion of
