Superficial perineal pouch Flashcards
What is in the superficial pouch of the perineum in males?
Root (bulb and crura of the penis and associated muscles (ischicavernosus and bulbospongiosus)
urethra
proximal bulbous - part of spongy urethra
superficial transverse perineal muscles
perineal artery, artery to the bulb of the penis (internal pudendal branches)
perineal nerve, posterior scrotal nerve, muscular branches
corpora cavernosa -crura
Corpus spongiosum - bulb
What is in the superficial pouch of the perineum in females?
Clitoris and associated muscles (ichiocavernosus)
bulb of vestibule and surrounding muscle (bulbospongiosus)
urethra , vagina
Greater vestibular gland (bartholin gland)
lesser vestibular glands (skenes gland)
superficial transverse perineal muscles
perineal artery, artery to vestibular bulb (internal pudendal branches)
corpora cavernosa - crura
vestibular bulb
What are the erectile tissue in females?
vestibular bulb
corpora cavernosa
Where is the vestibular bulb found?
around the vagina
What muscle covers the vestibular bulb?
bulbospongiosus
Where is the corpus cavernosus found?
crura of the vagina and clitoris
What muscle covers the corpus cavenosus?
ischicavernosus
What does the parasympathetic innervation does to the erectile tissue?
allows relaxation of smooth mm.
making the erectile tissue hard
What does the sympathetic innervation does to erectile tissue?
causes contraction of smooth mm.
making erectile tissue softer
What is the route that autonomic nerves take?
DIRECTLY THROUGH UROGENITAL HIATUS,
NOT RIDING WITH PUDENDAL NERVE
What are the autonomic nerves of the perineum?
SACRAL SPLANCHINC NERVES
PELVIC SPLANCHINC NERVES
What is erectile tissue in males?
corpora cavernosa -crura
Corpus spongiosum - bulb
Where is the corpus spongiosum in males?
surrounds the urethra
Where is the corpora cavernosa in males?
crura
What covers the corpus spongiosum in male s?
bulbospongiosum
What covers the corpora cavernosa in males?
ischiocavernosum
What does the corpus cavernous have surrounding it?
a thicker tunica albuginea =
more resistance
more pressure
more rigidity
What does the corpus spongiosum have surrounding it?
has a thinner tunica albuginea = less resistance less pressure more compressible Urethra runs entirely thorough this!
What is the purpose of the bulbourethral gland in males?
secretes an alkaline that reduces the acidity of the urethra tube
What is the phallaoplasty?
it is cutting the suspensory ligament making the penis hang further out of the body
What are the parts of the urethra?
prostatic
membranous (through pelvic diaphragm)- spots for most eruptions
spongiose (in corpus spongiosum)
What is the bucks fascia?
deep fascia of the penis?
What is the frenulum of the penis?
connecting the skin of the penis to the fascia
What are the layers of the penis?
skin fat bucks fascia corpus cavenosum inferiorly corpus spongiosum superiorly
