Cortical (Compact Bone) - ANS •Densely packed layers of collagen; solid bone
•Provides strength and rigidity
Role in weight bearing and protection 80% of sk mass
often involved in fracture
Trabecular (cancellous/spongy bone) - ANS a hierarchical, spongy, and porous material
composed of hard and soft tissue components, found at epiphyses and metaphyses
of long bones and in vertebral bodies
•Provides structural support by distributing forces applied to the bone.
•Spongy bone contains red bone marrow, which is responsible for hemopoiesis = producing red
blood cells, white blood cells, and platelets
Osteoporosis will often affect trabecular.
will heal faster because of an increased blood supply.

, Synovial Joints - ANS Move freely because bones are separated and enclosed in a joint cavity
filled with synovial fluid, allows sliding, which permits movement
Most affected by osteo-arthris rheumatoid arthritis and gout
Non-Synovial Joints - ANS Immovable or slightly movable
Trauma or structural changes can affect these
Bursa - ANS •Enclosed sac filled with synovial fluid
•Help muscles and tendons glide smoothly over bone
Can be affected by bursitis
Bone Remodeling: Resorption - ANS •osteoclasts remove areas of bone.
•Removal of hard bone tissue by osteoclasts
•Bone "chewers"
Bone Remodeling: Formation - ANS •osteoblasts then replace bone.
•New bone is formed by osteoblasts
•Bone "builders"
Bone health factors: - ANS Constant bone remodeling
•Destruction and reconstruction of bone
Dependent on calcium
