perineum Flashcards
list the layers for fascia and spaces of the perineum from inferior to superior/most superficial to deep in order
- skin
- superficial fascia/superficial perineal fascia (campers –> colles)
- deep perineal fascia (gallaudet’s fascia, bucks fascia)
- structures of the superficial perineal space (muscles)
- perineal membrane/inferior fascia of UG diaphrahm
- strucures of the deep perineal space (UG diaphragm)
- superior fascia of the UG diaphragm
name the muscles/components in space 4/superficial perineal space`
8 things
ischiocavernosus, bulbospongiosus superficial transverse perineal muscle crura and bulb of the penis/clitoris branches of perineal vessels and nerves greater vestibular gland (female)
name the muscles/components in space 6/the deep perineal space/UG diaphragm
8 things
sphincter uretrae muscle (anteriorly) deep transverse perineal muscle (posteriorly) branches of the internal pudendal vessels -urethral artery -artery of the bulb -deep artery of the penis/clitoris -dorsal artery of the penis/clitoris dorsal nerve of the penis/clitoris bulbourethral gland (in the male)
the root of the penis is made of the structures in which space
what are the components
the superficial perineal space
crura of corpora cavernosa
bulb (single midline mass of erectile tissue)
spongy/penile urethra
the body of the penis is composed of what structures
dorsal arteries of penis
deep dorsal vein of penis
dorsal nerves of penis
superficial dorsal vein of enis
paired dorsal corpora cavernosa
single ventral corpora cavernosa
-expands distally into glans penis
-three cylindrical masses covered by tunica albuginea
the mons pubis is
in female
mound of subcutaneous adipose tissue and hair in front of the pubic symphasis
erectile bodies deep to the ischiocavernosus muslce that diverge prosteriorly to follow and attach to the inferior ischial ramus and to the ichial tuberosity are:
corpora cavernosa penis
enlarged erectile tissue deep to the bulbospongiousus muscle is:
the bulb of the penis
the bulbospongiousus muscle is:
envelopes the bulb of the penis
expels the last of the urine, semen
aids in erection
the ischiocavernosus is:
covers the crura of the penis
maintains erection by compressing the crura, impedes venous return
