How does bone tissue repair
(regenerate) after a fracture?
Use the following anatomical structures in your answer;
blood vessels, spongy bone,
compact bone, osteocytes
Long Bone Structure
review
• Directions: READ ONLY…
This is review.
You already have these
notes!
Long Bone Structure
review
1. Shaft is known as the diaphysis.
2. Consists of a thick collar of
compact bone surrounding a
central marrow cavity
3. Expanded ends are epiphysis
4. Thin layer of compact bone
covering an interior of
spongy bone.
Periosteum
review
1. The external surface
of the entire bone
except for the joint
surfaces of the
epiphysis is covered
by a double-layered
membrane known as
the periosteum.
Bone Cells Osteocytes
review
Notes: Bone Healing and Repair
1. Bone cells at the site (place) of the fracture become
deprived (loss) of nutrients and bone cells die. The site
becomes swollen, painful, and inflamed.
2. White blood cells (WBC also known as macrophages)
begin to clean up all the debris (waste, dead cells).
3. Osteoblasts begin to form spongy bone.
4. This callus (like on your fingers if you play guitar, or on
your heel from friction) splints the broken bone.
Notes: Bone Healing and Repair
5. More spongy bone is
formed in about 6-8
weeks.
6.
Osteoclasts work to
remove the temporary
supportive structures
while osteoblasts rebuild
the compact bone and
reconstruct the bone so it
returns to its original
shape and structure.
Bone Healing and Repair – flow chart
Checking for Understanding:
Draw a flow chart.
Draw 6 boxes (or circles, triangles, etc.) to show
the 6 steps of bone fracture healing and repair.
End of the Skeletal System
Congratulations! You have now completed all the
objectives and standards of the skeletal system!
1. AP 2.1 Explain the anatomical position and the terms that describe relative positions, body
planes, and body regions. Describe the body cavities and the organs within each cavity; the
major organ systems; and their role in the functioning of the body.
2. AP 2.2 Distinguish bones according to shape and describe the major functions of bone.
Describe the structure of a typical long bone and indicate how each part functions in the
physiology and growth of the bone.
3. AP 2.3 Describe the types of cells found in bone and their role in bone growth and control of
bone mass.
4. AP 2.4 Distinguish the axial from the appendicular skeleton, and name the major bones of
each. Locate and identify the bones and the major features of the bones that make up the
skull, vertebral column, thoracic cage, pectoral girdle, upper limb, pelvic girdle, and lower
limb.
