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:
