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 corpora cavernosa are innervated by lesser and greater cavernous nerves and form most of the penis containing blood vessels that fill with blood to help make an erection. [8] The crura are the proximal parts of the corpora cavernosa. The corpus spongiosum is an erectile tissue surrounding the urethra.
In human male anatomy, the septum of the penis or penile septum refers to the fibrous junction between the two corpora cavernosa of the human penis.The tunica albuginea of the penis forms a thick fibrous coat to the spongy tissue of the corpora cavernosa and corpus spongiosum. [1]
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 ...
In human male anatomy, the radix (/ r eɪ. d ɪ k s /) [1] or root of the penis is the internal and most proximal portion of the human penis that lies in the perineum.Unlike the pendulous body of the penis, which is suspended from the pubic symphysis, the root is attached to the pubic arch of the pelvis and is not visible externally.

Each crus represents the tapering, posterior fourth of each corpora cavernosa penis; the two corpora cavernosa are situated alongside each other along the length of the body of penis while the two crura diverge laterally in the root of penis before attaching firmly onto either ischial ramus at their proximal end.

Chart of the generalized male reproductive system embryionic The genetic sex is determined by whether a Y bearing or next bearing sperm fertilizes the open; the presence or absence of a Y chromosome in turn determines whether the gonads of the embryo will be testes or ovaries; and the presence or absence of testes, finally, determines whether ...
