Identify the features of a

typical long bone.

1. Diaphysis (bone

shaft)

2. 2 epiphyses (both ends of the bone at the joints)

3. 2 metaphyses(region between diaphysis and epiphysis)

4. Articular cartilage covering both epiphyses

5. Periosteum (connective tissue surrounding the

diaphysis)

6. Medullary cavity (hollow space within diaphysis)

7. Endosteum (thin membrane lining the medulary cavity)

1. Describe the structure and function of both the periosteal and

endosteum layer of bone.

1. Periosteum: circulation and nerves, bone growth and

repair, joint capsule, ligament, tendonattachment (sharpey's

fibers)

2. Endosteum: bone growth, repair, and remodeling

1. Bone is considered connective tissue. Describe the cells, ground

substance and fibers that comprise bone.

1. Cells:

a. Osteoprogenitor cells (bone stem cells that can

diferentiate)

b. Osteoblasts (build bone by secreting matrix)

c. Osteocytes (mature bone cells)

d. Osteoclasts (remodel bone and cause them to

release calcium)

2. Extracellular Matrix: (same in compact and spongy bone)

a. Ground substance:
