1. Appendicular Skeleton
Bones of pectoral girdle & pelvic girdle
Bones of the upper & lower limbs
Differences between male & female pelvises

2. Pelvic girdle – where arms attach to axial skeleton

3. Figure 5.10

4. Features of pectoral girdle
Clavicles articulate medially with manubrium
Acromium process articulates with clavicle
Glenoid cavity articulates with humerus
Coracoid process = attachment for arm & chest muscles

6. Pelvic Girdle – where the legs attach to axial skeleton
os coxae of pelvic girdle formed by fusion of the
ilium,
ischium, and
pubis.
The pelvic girdle consists of two ossa coxae (ossa, bone + coxa, hip;singular).
At birth, these bones are separated by hyaline cartilage & fusion is usually complete by age 25
Acetabulum is where the 3 bones meet femur

8. Sex differences Female iliac bones more flared
Female ishial spines shorter
Female inlet larger, more circular
Female sacrum less curved
Female pubic arch is rounder
Female pelvis is shallower and lighter
