Question Answer
2 triangles of the perineumpasterior and anterior
descibe the relationship of the perineum to the pelvic diaphragminferior to the diaphragm
what is the other name and the contents of the posterior perineal trianglethe anal triangle and it contains the anal canal and the ischioanal fossa on either side
what is the contents of the anterior perineal triangleexternal genitalia and end of urogenital passages (urethra)
what divides the perineuma line joining the anterior portions of the ischial tuberosities
what is the central perineal bodythe center of the perineum, also called the central tendon of the perineum
what does the urogenital diaphragm lie onthe anterior perineal triangle, has the uerthra passing thru it
what is the urogenital diaphragma thin muscle between the pubic arch... covered by fascia AKA perineal membrane
describe the membranous fascia from the abdomen to the penis and scrotum to the perineumscarpies fascia, becomes dartos fascia when combined with the covering of the perineum, the colles fascia
describe the difference between the superficial and depp peroneal spacesthe superficial is between the superficial perineal fascia and the urogenital diaphragm... the deep is between the superior and inferior fascia of the urogenital diaphragm (contains sphincter [ext])
describe the contents of the superficial perineal spaceroot of penis and clit formed from crura and 2 bulbs... also contains the perineal body
contents of the deep perineal spacethe vagina, the urethra, ext sphincter, deep transverse perineal muscle
describe what the urethra sphincter muscle surrounds in males and femalesin females vagina and urethra, in males only urethra (membranous)
describe the origin of the urethral sphincter musclethe medial pubic ramus
what is the innervation of the urethral sphincter musclethe perineal nerve, branch of pudendal
3 portions of the male uretheraprostatic, membranous, spongy
what space are the bulbourethral glands inthe deep perineal space
descibe the origin and insertion of the deep transvers perineal musclefrom the ischial ramus, inserts on the perineal body (and vagina)
what is the difference between the urethra sphincter muscel and the deep transverse perineal musclethe urethra sphincter muscle arches anteriorly and compresses the urethra and the vagina while the deep transverse goes posterior to the vagina and supports the viscera... together they make a half circle
innervation of the transverse perineal musclepudendal nerve
4 muscles that insert on the perineal bodyBLT’s ... transverse perineal, levator ani, bulbospinous, sphincter
muscles cut in median epesiotomy vs mediolateralsuperficial perineal m, vs bulbospongious muscle
what are the lateral borders of the anal trianglethe sacrotuberous ligaments
which muscles overly the anal trianglethe glut max
3 contents of the anal fossaanal canal, ext anal sphincterm ischioanal fossa
where can you get abcesses around the rectuminto the ischoanal fossa
what is the innervation of the spuerior rectum versus the inferior portionthe superior is only autonomics, but the inferior is innervated by the inferior rectal nerves
part of the external anal sphincter is assisted by a muscle, what is itthe puborectalis
