what are the attachments of the coccygeus
originates the ischium and inserts at the lateral coccyx and lower lateral sacrum.
what are the attachments of the puborectalis
originates from the lateral aspect of the symphysis on both sides and encircles the rectum.
attachments of the iliococcygeus
originates at the ischial spine and tendinous arch and inserts at the coccyx, perineal body and anococcygeal raphe.
what are the attachments of the pubococcygeus
originates at the posterior surface of the pubis body and tendinous arch and inserts at the coccyx, perineal body and anococcygeal raphe.
what is the nerve supply to the pelvic floor and perineum
pelvic floor muscles - mostly nerve to levator ani and slight input from the pudendal nerve.
perineum - mostly pudendal nerve and slight input from the nerve to levator ani.
what are the functions of the perineal body
is the site of convergence for both muscles and fascia to form the pelvic floor.
located between the anus and vagina/bulb of penis.
what are the actions of the muscles of the perineum
provide added closure to the vagina and anus
support and fix the perineal body
maintain erection of penis/clitoris.
what muscles are apart of the perineum
urogenital triangle
- ischiocavernosus
- bulbospongiosis
- superficial transverse perineal
- deep transverse perineal
anal triangle
- external anal sphincter.
what organs are in males and females
female - bladder, urethra, rectum, anus, vagina and uterus
male - same but with prostate.
functions of pelvic floor
supports pelvic and abdominal viscera
contributes to and maintains intra-abdominal pressure
acts as sphincter for vagina and anus
assists in childbirth
types of endopelvic fascia and function
pubocervical - between bladder/urethra and vagina.
rectovaginal or rectoprostatic - between rectum and vagina or bladder and prostate.
uterosacral ligaments - suspend and support uterus and cervix in position.
provides a conduit for nerves and blood vessels to the organs and help maintain organs in place.
