Final Flashcards
Pelvic girdle (3 components)
*Connection b/t axial skeleton and lower limbs
- Hip bone/innominate x2
- Sacrum
- Coccyx
Male vs. Female Hips
Females= bigger subpubic angle (90-100 degrees)
Males= smaller subpubic angle (60-70 degrees)
Pelvic inlet (borders)
Anterior: pubic symphysis
Posterior: sacral promontory and ala
Lateral: iliopectineal line
Pelvic outlet (borders)
Anterior: pubic arch
Posterior: coccyx
Lateral: ischial tuberosity
True vs. False pelvis
False= superior to inlet *contains abdominal viscera
True= between inlet and outlet
Pubic symphysis joint type
Fibrocartiliganous
Hip joint type
Synovial ball and socket
*greater stability than mobility (compared to shoulder which is opposite)
Hip joint movements
-Abduction/adduction
-Flexion/extension
-Circumduction
Sacroiliac ligament attachments
Sacrum and ilium
Sacrospinous ligament attachments
Sacrum and ischial spine
Sacrotuberous ligament attachments
PSIS, sacrum and ischial tuberosity
Inguinal ligament attachments
ASIS and pubis
Function of pelvic floor (3)
-Supports abdominal and pelvic viscera
-Forms anal and urogenital hiatuses
-Resists increases in intra-abdominal pressure
Where does the femoral artery enter the lower limb and what does it pass through
Inguinal ligament (then passes through adductor canal)
Where does profunda femoris pierce/pass through
Medial compartment muscle
