Anatomy-Skeletal System Appendicular Skeleton Lower Extremity

Anatomy-Skeletal System Objectives • Students will be able to: • Define anatomical terms. • Identify the bones of the lower extremity of the appendicular skeleton. • Label the bones.

Anatomy-Skeletal System Terminology • Appendicular Skeleton • The part of the skeleton that include the shoulder, pelvis, upper and lower limbs.

Anatomy-Skeletal System Terminology • Lower extremity • Includes the pelvis, thigh, knee cap, leg, ankle, foot and toes.

Anatomy-Skeletal System Terminology • Tubercle • Small size bump on a bone • Tuberosity • Medium size bump on a bone • Trochanter • Large size bump on a bone
