Overview and Review of the Pelvis and Perineum 1 Flashcards
_____________ is suturally attached to axial skeleton to facilitate transmission of locomotor energy generated by legs to rest of body.
Pelvic girdle
the SCIATIC NERVE exits the pelvis through the ____________.
greater sciatic foramen
Ligament running from sacrum to ischial tuberosity is _________________. Its presence closes off lesser sciatic notch to become __________________.
1) SACROTUBEROUS LIGAMENT 2) lesser sciatic foramen
Ligament running from sacrum to ischial spine is _________________. Its presence closes off greater sciatic notch to become ___________________.
1) SACROSPINOUS LIGAMENT 2) greater sciatic foramen
The ____________ and _________________ passes thru the greater sciatic foramen and comes out of the lesser sciatic foramen.
1) pudendal nerve
2) internal pudendal artery
Perineal Musculature are _______________ with three layers
name them?
hypaxial musculature
1) External layer
2) Middle layer
3) Deep layer
the External Layer is reffered to as the _____________ (external sphincters) that include both the external anal sphincter and the ___________________.
1) Urogenital diaphragm
2) external urethral sphincter
A major component of the urogenital diaphrags is the ________________
deep transverse perineal muscle
The urogenital diaphragm (external sphincters) is made of _______________, meaning that we have conscious control over them.
striated muscles
Internal sphincters are made out of _______________
smooth muscles
The middle layer is reffered to as the _____________.
Pelvic diaphragm
the Pelvic diaphragm can be divided into
1) ___________
2) ___________
1) Levator ani (raises the anus)
2) Coccygeus
The deep layer is known as the ________________a
Transversalis fascia
The Superficial layer is innervated by the ______________ going to the urogenital diaphragm meaning to both sphincters of your ________ and _________
1) Pudendal nerve (S2,3,4)
2) urethra
3) anus
the Pudendal nerve is ___________ ( which means sensory and motor ) not autonomic, for that reason it is not the same as the hindgut parasympathetic innervation.
Somatic innervaton
Pudendal means ___________ meaning that it covers the parts we are ashamed off. what a bikini would cover
shameful
the Middle layer Nerve goes to pelvic diaphragm _________
(S4,5)
the Deep layer is reduced to _________ meaning there is no motor innervation necessary.
fascia
Deep perineal space lies ________________ (transversalis fascia).
internal to deepest layer
_______________ lies between urogenital diaphragm and pelvic diaphragm.
Ischiorectal fossa
_________________ is between urogenital diaphragm and superficial fascia in things like your skin.
Superficial perineal space
Superior gluteal artery runs with superior gluteal nerve through greater sciatic foramen and ________________.
over piriformis muscle
Inferior gluteal artery goes through greater sciatic foramen, but runs with ____________ and runs below piriformis muscle.
inferior gluteal nerve
(Internal) Pudendal artery travels with _____________e
Pudendal nerve
terminal end of the R/L internal iliac artery was the fetal _____________.
you should be able to find it in continuity with the umbilicus via the ________________________.
