1. Appendicular Skeleton Continued
Marieb Exercise 11, pgs

2. Pelvis and Pelvic Girdle
2 coxal bones form girdle
plus sacrum and coccyx = pelvis
anterior articulation at pubic symphysis
posterior articulation with sacrum (sacroilliac)

3. False Pelvis false (greater): portion superior to pelvic brim or inlet
supports abdominal viscera, but DOES NOT restrict childbirth

4. True Pelvis true (lesser): pelvic brim or inlet and inferior
encloses the pelvic cavity
dimensions are critical for childbirth
pelvic inlet: superior most opening
pelvic outlet: inferior most opening

5. Male vs. Female Pelvis See Table 11.1 in Marieb for details Females
wider pelvic inlet and outlet
wider pubic arch

6. Coxal Bones: 3 fused regions
Ilium, Ischium, & Pubis
Acetabulum (wine cup)
where the 3 bones fuse
recieves the head of the femur
Obturator foramen
hole formed by fusion of pubis and ischium
blood vessels and nerves pass from pelvic cavity into thigh

7. medial view
Ilium
iliac crest
iliac spines mark attachment of muscles and ligaments:
anterior superior iliac spine (ASIS)
anterior inferior iliac spine (AIIS)
Posterior SIS
PIIS
greater sciatic notch
sciatic nerve passes to lower limbs
lateral view

8. ischium ischial spine ischial tuberosity lesser sciatic notch
medial view
ischium
ischial spine
posterior to acetabulum
ischial tuberosity
bear body weight when seated
lesser sciatic notch
blood vessels, nerves and a small muscle pass here

10. Femur Greater and Lesser Trochanter Head Neck linea aspera
where large tendons attach
to the femur
Head
fovea capitis
where ligament attaches femur to acetabulum of pelvis
Neck
linea aspera
attachment
of hip muscles

11. Femur medial/lateral condyles adductor tubercle
knee joint
adductor tubercle
adductor magnus muscle
popliteal surface (fossa)
posterior
patellar surface (fossa)
anterior

12. Patella A sesamoid bone enclosed in quadriceps tendon
secures anterior thigh muscle to tibia

13. Tibia (shin bone) larger medial leg bone medial/lateral condyles
knee joint with femur
intercondylar eminence
tibial tuberosity
attachment of patellar ligament

14. Tibia (shin bone) medial malleolus fibular notch
forms inner bulge of ankle
fibular notch
articulates with fibula

15. Fibula Lateral smaller bone lateral malleolus head
forms outer bulge of ankle
head
articulates with lateral condyles of tibia

16. The Foot
7 tarsals
5 metatarsals
14 phalanges

17. The Foot
2 largest tarsals support body weight
calcaneus
talus

18. The Foot Other 5 Tarsals Navicular 1st-3rd cuneiforms Cuboid
medial, intermediate, lateral
Cuboid

19. The Foot
Metatarsals (5)
1st-5th
start at big toe

20. The Foot Phalanges (14) metatarsal 1 metatarsal 2-5
proximal and distal only
metatarsal 2-5
proximal, middle and distal
