HESI A2 2024-A&P- Skeletal System
Endosteum
Lining the inside of the bone adjacent to the medullary cavity is a layer of bone cells that cause
the bone to grow, repair, and remodel throughout life.
Periosteum
Part of the outer double layered structure on the outside of bones that grow, repair and remodel
bone as well.

Osteoblasts
undergo mitosis and secrete a substance that acts as the framework for bone. Once this
substance (called osteoid) is secreted, minerals can deposit and form hardened bone. Bone
forming cells. cells that synthesize bone matrix and coordinate the mineralization of the
skeleton.
Osteocytes
mature bone cells. The longest living bone cell, making up 90-95% of cells in bone tissue.
Cannot divide by mitosis.
, Osteoclasts
Are capable of demineralizing bone. They free up calcium from bone and release it into the
blood depending on the body's needs. The cells that degrade bone to initiate normal bone
remodeling and mediate bone loss in pathological conditions by increasing their resorptive
activity.
Diaphysis
shaft of is the hollow, tubular shaft that runs between the proximal and distal ends of the bone.a
long bone.
Epiphysis
The area of the long bone where bone growth takes place.
How many bones does the adult human body have?
206
3 multiple choice options
4 types of bones categorized according to shape
Flat, long,short, irregular
Long bones
have a long longitudinal axis
Short bones
have a short longitudinal axis and are more cube-like
Flat bones
thin, flattened, and usually curved.
irregular bones
