• Temperature regulation, energy storage, filtration
• structure, strength, mobility

• Nutrition, flexibility, endurance

Long bones have a _____(main center), ______, and are made of _______ bone on the outside and covering the shaft and _______ bone on the ends.

• shaft, 2 ends, compact, spongy

• cancellous

• medullary cavity
• diaphysis, epiphyses, cortical bone, trabecular bone

• lengthen

What is the largest long bone?

• femur
• tibia
• humerus
• radius

makes up the middle long shaft of the bone, composed of compact bone.

• epiphysis
• periosteum
• metaphysis
• diaphysis

Makes up the ends of the long bones, composed of spongy or cancellous bone.

• Diaphysis
• Metaphysis
• Periosteum
• Epiphyses

This lies in between the diaphysis and epiphysis and is composed of hyaline cartilage when a person is young (plate-growth plate), and turns to hard bone once fully grown (line).

• Epiphyseal plate/line

• Medullary cavity/line

• Articular cartilage/line

• Growth line/long plate

The growth of a bone comes from the

• growth plates
• medullary cavity
• periosteum
• epiphyseal plates
