Pelvis Flashcards
(30 cards)
what are the 3 bones that make up the os coxae in superior to inferior order
illium, ishium, pubis
illness is pub
what are the all the bones of the pelvis/pelvic girdle?
os coxae (illium, ishium, pubis), sacrum, and coccyx
What are 3 important soft tissue structures that attach to the ASIS of the Pelvis?
tensor fascia latae, inguinal ligaments, Sartorius
“Sartorius has liguini and lataes at the ASIS”
What inferior part of a two part muscle attaches at the iliac fossa of the pelvis?
illiacus (combined with psoas which extends from lower lumbar laterally to form the iliopsoas)
what two muscles use the ishial tuberosities of the pelvis for attachment?
Hamstrings, Adductor Magnus
“people ADD MAGNets that attract HAM on the Sit Bones”
The Pubis can be broken up into two parts, what are they?
Body, Ramus (superior and inferior rami)
What is the structure that joins the two pubis bones?
symphysis pubis
What are some of tissues that attach at the pubis?
obturator internus, pectineus, Adductor Magnus/brevis, and gracilis
What is the greater sciatic notch?
an opening under the PSIS that is made by the sarcrospinous and sacrotuberous ligaments where structures pass through.
which tissues pass through the sciatic notch?
sciatic nerve, piriformis
the superior and inferior gluteal vessels and nerves, the sciatic and posterior femoral cutaneous nerves, the internal pudendal vessels, and the nerves to the Obturator internus and Quadratus femoris
The greater trochanter is lateral? where is the lesser trochanter located?
medially
What are the 3 ligaments that reinforce the hip joint and hip capsule?
iliofemoral, ishiofemoral, pubofemoral
“illness is Pub”
iliofemoral ligament does what? other names for it?
reinforces the hip joint anteriorly. limits hyper extension
“y ligament” “the ligament of BIGELOW”
pubofemoral ligament does what?
reinforces medially and inferiorly. limits hyper extension and abduction
ishiofemoral ligament does what?
reinforces posteriorly. Limits hyper extension and medial rotation
Which ligaments allow for a paraplegic person to stand upright as long as they thrust their shoulders and hips forward?
the spiral attachment of the those pesky hip ligaments :) since they do such a good job at limiting hyperextension.
