What are the five functions of the skeletal system?
What are the five functions of the skeletal system?
The skeletal system supports and protects the body, allows movement, makes blood cells, and stores minerals and fat.
Describe the anatomical features of a long bone.
Describe the anatomical features of a long bone.
A long bone has an epiphysis (ends) made of spongy bone with red marrow, a diaphysis (shaft) with compact bone, and a medullary cavity filled with yellow marrow. It also has periosteum (outer layer) and endosteum (inner layer).
Where do we find spongy bone compared to compact bone?
Where do we find spongy bone compared to compact bone?
Spongy bone is found at the ends (epiphysis) of long bones and inside flat bones. Compact bone forms the outer layer of all bones and the shaft (diaphysis) of long bones.
