consists of 80 bones that revolve around the vertical axis of the skeleton
What consists of the Axial Skeleton?
Skull, Facial Bones,Thoracic cage & vertebral column
Appendicular Skeleton
Consists of 126 bones that append to the axial skeleton
What consists of the Appendicular Skeleton?
Pectoral girdle, Upper Limb, Pelvic Girdle & Lower Limb
What are the functions of the Axial Skeleton?
Protects brain and internal organs, provides structure and support & attachment for muscles
What are the functions of the Appendicular Skeleton?
Protection, attachment for muscles, support and movement & blood cell formation
What are long bones?

Humerus and femur
What are short bones?
are as wide as they are long

What is cartilage?
a flexible connective tissue found between the bones of joint. It acts as a cushion between
joint and reduces friction in movement
What is a ligament?
dense, flexible tissue that connects bone to bone at a joint
What is a tendon?
consists of dense collagen fibers and connect muscle to bone
What is a joint?
