spongiosum การใช้

• This is homologous with the corpus spongiosum of the male anatomy.
• The male corpora cavernosa taper off internally on reaching the spongiosum head.
• It is about 15 16 cm in length, and travels through the corpus spongiosum.
• Though the bulbs are considered the equivalent of the male spongiosum, they do not completely encircle the urethra.
• The "'corpus spongiosum "'is the mass of spongy tissue surrounding the male urethra within the penis.
• On its ventral aspect, it splits to envelop corpus spongiosum in a separate compartment from the tunica albuginea and corporal bodies . 65
• The thin corpus spongiosum of the penis runs along the underside of the penile shaft, enveloping the urethra, and expands at the end to form the glans.
• The external envelope or outer coat of the corpus spongiosum is formed partly of unstriped muscular fibers, and a layer of the same tissue immediately surrounds the canal of the urethra.
• The third, called the corpus spongiosum, is a tube that lies centrally beneath the others and expands at the end to form the tip of the penis ( glans ).
• The male anatomy has no vestibular bulbs, but instead a corpus spongiosum, a smaller region along the bottom of the penis, which contains the urethra and forms the glans penis.
• Upon anatomical study, the penis can be described as a clitoris that has been mostly pulled out of the body and grafted on top of a significantly smaller piece of spongiosum containing the urethra.
• The enlarged and bulbous-shaped end of the corpus spongiosum forms the glans penis, which supports the foreskin, or prepuce, a loose fold of skin that in adults can retract to expose the glans.
• Proximal shunts, such as the Quackel's, are more involved and entail operative dissection in the perineum to where the corpora meet the spongiosum, making an incision in both, and suturing both openings together.
• There is also a strip of erectile tissue ( similar to the placement of the corpus spongiosum in males ) running along the ventral surface of the corpus canervosa main body that connects the glans clitoridis to the commissure of the vestibular bulbs.
• The corpora cavernosa are homologous to the body of the clitoris; the corpus spongiosum is homologous to the vestibular bulbs beneath the labia minora; the scrotum, homologous to the labia majora; and the foreskin, homologous to the clitoral hood.
• In the bulbar urethra, the most common types of urethroplasty are anastomotic ( with or without preservation of corpus spongiosum and bulbar arteries ) and substitution with buccal mucosa graft, full-thickness skin graft, or split thickness skin graft . These are nearly always done in a single setting ( or stage ).
• The vestibular bulbs are homologous to the bulb of penis and adjoining part of the corpus spongiosum of the male, and consist of two elongated masses of erectile tissue, placed one on either side of the vaginal orifice and united to each other in front by a narrow median band termed the " pars intermedia ".
• As in humans, the dorsal nerve distribution was unique in being devoid of nerves at the 12 o'clock position in the penis and clitoris of the spotted hyena " and that " [ d ] orsal nerves of the penis / clitoris in humans and male spotted hyenas tracked along both sides of the corporeal body to the corpus spongiosum at the 5 and 7 o'clock positions.
