What are the functions of the skeletal system? Locomotion, support, protection, site of blood production and mineral storage
How does it help locomotion? Skeletal system provides points of attachment for muscles, limbs move when muscles pull on bones
How does it support? Backbone = main support center for vertebrate body, holds head + protects spinal cord
How does it protect? Bones of skull protect brain, ribs protect (+ help ventilate) the lungs and protect heart
Give two examples of mineral storage Calcium, phosphorus

What is the axial skeleton? Bones of head, vertebral column and ribs + sternum
What is the appendicular skeleton? Bones of limbs
