Long Bones = Most bones of the limbs Short Bones = Like cubes/marshmallows eg. carpal & tarsal bones Flat Bones = Thin & flat eg. skull, scapulae, pelvic bones Irregular Bones = Miscellaneous eg. vertebrae, some skull bones, sesamoid bones (many are in tendons) - patella Signup and view all the answers

Bone membranes matching

Endosteum = A membrane lining the hollow interior surface of bones (lines the medullary cavity and trabeculae) Endosteum = Function: contains cells involved in bone growth, remodelling and repair Periosteum = A membrane covering the outer surfaces of bones (except the articular/joint surfaces) Periosteum = Function: contains blood vessels and nerves that supply bones Also contains cells involved in growing and repairing bone Signup and view all the answers
