Long bones: Clavicle, ulna, radius, femur, phalanges, humerus, metacarpals, fibula, tibia.
Long bones have growth plates (epiphysis) at either end. They have a hard outer surface and a spongy inner which is the cancellous part of the bone containing bone marrow. Both ends are covered in hyaline cartilage which helps protect the bone and absorb shock.

Short bones: Tarsals, carpals.
The primary function of a short bone is to provide support and stability with little movement. They only consist of a thin layer of hard bone with cancellous bone which have large amounts of bone marrow in.

Flat bones: Cranium, sternum, ribs, mandible, scapula.
Flat bones are as they sound,flat plates of bone. They provide protection to the bodies vital organs and

Usually a short or irregular bones Sesamoid bones are usually present in a tendon where it passes over a joint which serves to protect the tendon.

Function of the skeletal system
Support: Bone and cartilage make up the skeletal system and are the only rigid material in the body; they provide the framework and points of attachment for most of the soft tissue throughout the body.
Protection: Protects your internal and fragile tissue in the body, for example the cranium protects the brain which is a vital organ.
Attachment for skeletal muscle: Skeletal muscle consists of two kinds of tissue, connective and muscle tissue. Connective tissue is layers of connective tissue and serves as a connecting function. Tendons attach the connective tissue to the bones.
Leverage: Every part of body provides an attachment to the muscles allowing for the muscles to do the moving and the bones to lever to do certain movements for example lift your arm up.
Source of red blood cell production: the sternum and the tibia heads have hemopoetic activity/blood cells production, these areas produce new blood cells.
Store of minerals: Bone tissues store several minerals, calcium and phosphorus when required to do so. The bones then release the minerals into the blood
