• maintenance of body temperature

• protection

The ends of a long bone are called the

• diaphysis

• epiphyses

• periosteum

• endosteum

Bone forming cells:

• osteocytes

• osteoblasts

• osteoclasts

• osteomasts

Bone destroying cells:

• osteocytes

• osteoblasts

• osteomasts

• osteoclasts

Must be present in the blood at all times for the nervous system to transmit messages, for muscles to contract, and for blood to clot:

• calcium

• adipose tissue

• phosphorus

• iodine

Activates osteoblasts to break down bone matrix so calcium is released into the blood:

• osteoclasts

• osteocytes

• adipose tissue

Mature bone cells:

• osteoblasts

• osteomasts

• osteocytes

• osteoclasts

Remnant of the growth plate:

• epiphyseal plate

• spongy bone

• epiphyseal line

• lacunae

The long shaft of a bone:

• epiphyses
