Pelvis

Question 1

what are the 3 bones that make up the os coxae in superior to inferior order

Answer 1

illium, ishium, pubis

illness is pub

Question 2

what are the all the bones of the pelvis/pelvic girdle?

Answer 2

os coxae (illium, ishium, pubis), sacrum, and coccyx

Question 3

What are 3 important soft tissue structures that attach to the ASIS of the Pelvis?

Answer 3

tensor fascia latae, inguinal ligaments, Sartorius

“Sartorius has liguini and lataes at the ASIS”

Question 4

What inferior part of a two part muscle attaches at the iliac fossa of the pelvis?

Answer 4

illiacus (combined with psoas which extends from lower lumbar laterally to form the iliopsoas)

Question 5

what two muscles use the ishial tuberosities of the pelvis for attachment?

Answer 5

Hamstrings, Adductor Magnus

“people ADD MAGNets that attract HAM on the Sit Bones”

Question 6

The Pubis can be broken up into two parts, what are they?

Answer 6

Body, Ramus (superior and inferior rami)

Question 7

What is the structure that joins the two pubis bones?

Answer 7

symphysis pubis

Question 8

What are some of tissues that attach at the pubis?

Answer 8

obturator internus, pectineus, Adductor Magnus/brevis, and gracilis

Question 9

What is the greater sciatic notch?

Answer 9

an opening under the PSIS that is made by the sarcrospinous and sacrotuberous ligaments where structures pass through.

Question 10

which tissues pass through the sciatic notch?

Answer 10

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

Question 11

The greater trochanter is lateral? where is the lesser trochanter located?

Answer 11

medially

Question 12

What are the 3 ligaments that reinforce the hip joint and hip capsule?

Answer 12

iliofemoral, ishiofemoral, pubofemoral

“illness is Pub”

Question 13

iliofemoral ligament does what? other names for it?

Answer 13

reinforces the hip joint anteriorly. limits hyper extension

“y ligament” “the ligament of BIGELOW”

Question 14

pubofemoral ligament does what?

Answer 14

reinforces medially and inferiorly. limits hyper extension and abduction

Question 15

ishiofemoral ligament does what?

Answer 15

reinforces posteriorly. Limits hyper extension and medial rotation

Question 16

Which ligaments allow for a paraplegic person to stand upright as long as they thrust their shoulders and hips forward?

Answer 16

the spiral attachment of the those pesky hip ligaments :) since they do such a good job at limiting hyperextension.
