Central Canal
A general term for inflammation or disease of one or more joints.
Arthritis

Rickets
What are the two most commonly replaced joints?
The hip and knee joints
One extremity remains stationary while the rest of the body is moving.

Osteoclasts
What gland monitors the level of calcium in our blood?

Arthroscope
What is a Greenstick Fracture?

Define Hematoma
A collection of blood that forms around damaged tissue after blood vessels are broken.
Blunt trauma applied perpendicular to the bone.
(There are two types)
Transverse & Oblique Fractures
These are inside the central canal.
(There are 4)
Artery, vein, nerve, and lymphatic vessel.
Approximately how much of our bone mass is recycled every week through bone remodeling.
(Give percentage)
Approximately 5-7%
Why must a broken bone be properly aligned and immobilized while it heals?
Alignment allows the bone ends to reconnect in the correct position. Immobilization prevents movement that could interrupt healing or cause the bone to heal crookedly.
