Flashcards in Innominates Dougherty Pre-Lecture Deck (24):
1

what joint is medial, posterior, and superior and its function

sacroiliac joint and transmits weight from the axial spine

2

what jiont is medial anterior and inferior and its function

pubic symphysis
point of stabiliztion for both hips

3

what 2 forces keep the symphysis together

strong posterior ligaments
sacroiliac joint

4

what is an accessory ligament

ligament that attaches from bone to another ligament, a tendon or other fascia

5

what are the 4 major pelvic ligaments

Iliolumbar: ilia to 5th lumbar verterbrae

Sacrospinous: sacrum to spine of ischium

sacrotuberous: sacrum to ischial tuberosity

sacroiliac ligament: SI joint, posterior and anterior

6

function of iliolumbar ligament

restrict anterior motion of L-5 maybe rotatory movements as well

7

sacrospinous ligament divides space above and below into what and ligament is part of what

greater and lesser sciatic foramen
part of coccygeus muscle

8

sacrotuberous ligament function

restrains anterior movement of sacrum

9

what attaches to sacrotuberous ligament

gluteus maximus
long head biceps femoris tendon
piriformis
connects with fascia of pelvis

10

anterior SI ligament

from 3rd sacral segment to auricular surface of ilium and lateral preauricular sulcus

11

interosseous SI ligament

deep to posterior SI lig
bond between upper parts of the joint (connects tuberosities)

12

posterior SI ligament

partly covers interosserous, from lateral sacral crest to PSIS and internal iliac crest

13

pubic symphysis

secondary cartilaginous joint
surface of bones covered with hyaline cartilage and bones united by strong fibrous CT or fibrocartilage

Fibrocartilagenous joint

14

muscles acting at hip: flexors and extensors

flexors pull pelvis anteriorly
extensors pull pelvis posteriorly

15

hip flexors

iliacus and psoas (major)

rectus femoris and sartorius
adductor longus and brevis
pectineus and gracillis

RAP SG

16

extensor medial hamstring group

semimembranosus
semitendinosus
gracillis
sartorius

17

extensor lateral hamstring group

biceps femoris

18

extensor group other 2 muslces

gluteus maximus
adductor magnus

19

2 minor adductor muscles

gracilis
pectinius

20

adductor group attachment

all attach to the pubic ramus and medial/and or posterior femur

21

abudcutors of hip

gluteus medius and minimus
TFL

22

external rotators of hip

piriformis
gamellus superior
obturator internus and externus
gamellus inferior
quadratus femoris

23

piriformis and sciatic n

10-12% of population has sciatic nerve piercing it so contraction can cause sciatica

24

piriformis function

when hip flexed it is an abductor
when hip extended it is an external rotator
