Helpful And Clinical Notes (Olinger) Flashcards
The bony pelvis includes ___
The __ describes the paired coxal bone, which are joined anteriorly at the pubic symphysis
Paired coxal bones, sacrum, and coccyx
Pelvic girdle
The ___ is known as the pelvic inlet and exists at the pelvic brim, between greater and lesser pelves, and is formed by the sacral promontory, superior edge of sacral ala, arcuate line of ilium, pectin pubis, posterior edge of pubic crest and superior edge of the pubic symphysis
Superior pelvic aperture
The __ is known as the pelvic outlet and is bound by inferior edge of pubic symphysis, inferior pubic and ischial rami, ischial tuberosities, sacrotuberous Ls., and the coccyx
Inferior pelvic aperture
The ___ is the passage between the superior and inferior pelvic apertures
Pelvic canal
Compare male vs female pelves:
Males: thicker, heavier pelves; deeper greater pelvis, narrower and deeper lesser pelvis, android pelvic inlet, small pelvic outlet, narrow pubic arch, round obturator foramen, large acetabulum
Females: thinner, lighter pelves; shallow greater pelvis, wide and shallow lesser pelvis, gynecoid pelvic inlet, large pelvic outlet, wide pubic arch, oval-shaped obturator foramen and small acetabulum
___ is the classically-shaped male pelvis
___ is the classically-shaped female pelvis
Android
Gynecoid
Which features of the pelvis are often broken as a result of a pelvic fracture?
Superior and inferior pubic rami–> difficult to break in only one place
Which ligaments produce the greater and lesser sciatic foramina?
Sacrotuberous and sacrospinous l.
Define the borders of the quadrangular space of the perineum and how the urogenital and anal triangles are formed
Anterior: Pubic symphysis
Posterior: coccyx
Laterally: Ischial tuberosities
Draw a line between 2 ischial tuberosities and quandrangle is divided into 2 triangular spaces (urogenital is anterior and anal is posterior)
The ___ is an irregular fibromuscular mass in the midline between the anal canal and perineal membrane, and contains collagenous and elastic fibers. It is the attachment point for bulbospongiosus, external anal sphincter, superficial and deep transverse perineal muscles.
Perineal body
The ___ is sometimes classified as a central tendon of the pelvic and urogenital diaphragms
Perineal body
The ___ in the female is described as being smooth muscular mass along the posterior edge of the perineal membrane
Deep transverse perineal m.
The pelvic diaphragm is made of these 4 muscles:
The levator ani muscle is made of these 3 muscles from medial to lateral:
Levator ani (puborectalis, pubococcygeus, iliococcygeus) and coccygeus
Puborectalis, pubococcygeus, iliococcygeus
The superficial fascia of the pelvic diaphragm contains small slips of muscle that insert onto the urinary bladder, those muscles are the __ muscle from the pubis to the urinary bladder and the __ muscle from the rectum to the urinary bladder
Pubovesicalis muscle
Rectovesicalis muscle
The pubococcygeus m. Produces several small slips of muscle that extend to nearby structures, all sharing similar action and innervation as the pubococcygeus m. These muscles include the ___
Levator prostate m. (Male)
Pubovaginalis m. (Female)
Puboperinealis m.
Puboanalis m.
