Module 4: Hip, Pelvis, Anterior Thigh Flashcards
Movements of Pelvis
Pelvic Tilt (anterior, posterior, lateral)
Functions of Pelvis
Weight bearing, weight transference, protection of organs
Endopelvic Fascia (2 examples)
Tendinous arch of levator ani, tendonous arch of pelvic fascia
Muscles of Levator Ani
Puborectalis, Pubococcygeus, Iliococcygeus
What is the perineal body
CT structure between vagina/penis and anus (anchor point, attachments for muscles)
Action of pelvic floor muscles
Act like a slingshot, lifting anteriorly and superiorly to maintain continence
Function of coccygeus
Draws coccyx anteriorly following defecation/childbirth (parturition)
Superficial Pelvic Floor Muscles (how many? function?)
4 muscles, help with sexual function and continence
What does the Pudendal nerve supply
