(Pelvic Girdle, Structures): Ischium

Answer 27

Makes up lower and back portion of hip.

Fuses with ilium and pubis.
pg 21

Question 28

(Pelvic Girdle, Structures): Pubic bones (pubis)

Answer 28

Joins together at the pubic symphysis

pg 21

Question 29

Pectoral Girdle

Answer 29

Supports upper extremities

Question 30

(Pectoral Girdle, Structures): Scapula (shoulder blade)

Answer 30

Attachment point for several muscles which allow flexible upper body movement and strength.

Attaches to axial skeleton only via clavicle.
pg 21

Question 31

(Pectoral Girdle, Structures): Clavicle (collarbone)

Answer 31

Attaches to sternum and scapula.

Provides anterior support for scapula.
pg 21

Question 32
