2

Arm bone

Humerus

3

Bones of the shoulder girdle

19

How is the arm held clear of the widest dimension of the thoracic cage

20

Total number of phalanges in hand

14

21

22

What organs are protected by the pelvic girdle?

Reproductive organs, urinary bladder, part of the large intestine

23

Distinguish between true and false pelvis.

False pelvis makes up the larger part of the pelvis. Superior. Supports abdominal viscera.

True pelvis is the inferior region, and the cavity is short and small-bowled shape that encases the urinary bladder and reproductive organs

24

For what anatomical reason do women appear to be slightly knock-kneed?

Women have wider pelvises than men. Angle of hips turn slightly inward, giving that appearance.

25

How might this anatomical arrangement contribute to knee injuries in women?

More prone to knee injuries such as ACL tears due to high stress/impact directly to knee

26

What does fallen arches mean?

Ligaments and tendons are weakened which allow the bones to fall. Causes appearance of flat feet.

27

What 3 bones fuse to form the coxal bone?
