The dorsal nerve of the penis is the deepest of three divisions of the pudendal nerve; it accompanies the internal pudendal artery along the ramus of the ischium; it then runs forward along the margin of the inferior ramus of the pubis, between the superior and inferior layers of the fascia of the urogenital diaphragm.

As part of the glans penis, the frenulum is innervated by divisions of the pudendal nerve; the dorsal nerve of the penis and a branch of the perineal nerve. [ 10 ] [ 11 ] Blood supply to the frenulum is provided by branches of the dorsal artery of the penis that curve around each side of the neck to enter the frenulum and the glans from its ...
The corona of glans penis (or, directly from the Latin, the corona glandis penis [1]) or penis crown refers to the rounded projecting border or flare that forms at the base of the glans in human males. The corona overhangs a mucosal surface, known as the neck of the penis, which separates the shaft and the glans. [2]

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 vas deferens has a dense sympathetic innervation, [16] making it a useful system for studying sympathetic nerve function and for studying drugs that modify neurotransmission. [7] It has been used: as a bioassay for the discovery of enkephalins, the endogenous opiates. [17] to demonstrate quantal transmission from sympathetic nerve terminals ...
