Epiphysis

Ends of the long bone, it's function is to allow the joints of bones to move together easier. Made up of both spongy bone, which contains blood marrow and red blood cells, and cartilage, which covers the surface of this part of the bone.

New cards

Spongy bone

Red marrow is stored here, and blood cell production occurs here. Absorbs shock/strain that is put on the bones during movement.

Articular cartilage

Covers the ends of the bone where they come together to form joints, main function is to reduce friction between bones.
