Olinger Flashcards
Describe the fascia lining the inside of the obturator internus m.
Obturator fascia
Made up of parietal membranous pelvic fascia
What type of fascia lines the uterosacral ligament?
Parietal membranous pelvic fascia
[the uterosacral ligament is part of the tendinous arch of pelvic fascia, both of which are made of this parietal membranous pelvic fascia!]
What type of fascia surrounds the urinary bladder?
Vescial fascia, which is made up of visceral membranous pelvic fascia
What passageway runs through the obturator fascia?
Pudendal canal
[know that the pudendal canal is made up of obturator fascia!]
2 types of endopelvic fascia
Condensed
Loose
Is paravesical space the same as paravesical fossae?
No; if we line paravesical space (which is just fat filled space) with peritoneum then it becomes paravesical fossae
Hypogastric sheath = in pelvic floor; 3 lamina - anterior, posterior and middle — What type of fascia makes up the hypogastric sheath?
Why is the middle lamina the most significant of the 3?
Condensed pelvic fascia
Middle lamina = transverse cervical ligament (aka cardinal ligament)
[KNOW that the transverse cervical ligament is made up of condensed pelvic fascia!]
Innervation of superficial transverse perineal m.
Deep perineal n.
Innervation of bulbospongiosus m.
Deep perineal n.
Innervation of ischiochavernosus m.
Deep perineal n.
What is the difference in naming for erectile tissue vs. the muscle associated with it?
Erectile tissue ends in “um” corpus spongiosum
While muscle ends in “us” like bulbospongiosus m
What does the pelvic diaphragm separate?
Pelvis from perineum
Thin layer of m. on sacrospinous ligament
Coccygeus m.
What innervates obturator internus m.?
Nerve to obturator internus
[NOT THE OBTURATOR N.!! Different things]
