The periosteum grow (appositional growth) bone tissues and provide muscle and tendon attachment. The periosteum is composed of dense irregular connective tissue and osteoblasts, connected to bone through Sharpey's fibers. The two layers are the fibrous layer and the osteogenic layer.

Describe the cause, symptoms, and treatment of osteomalacia and rickets. What is the difference between the two?

Describe the cause, symptoms, and treatment of osteomalacia and rickets. What is the difference between the two?

Answer! (Click to Show Hidden Text)

Cause is Vitamin D deficiency either from dietary or lack of sun exposure. Weakening of bone hardness due to lack of absorption of calcium from Vitamin D deficiency. Bones become soft and palpable, and in some cases bending. Symptoms include bone growth delay or pain or weakness in legs, pelvis or spine. Treatments invove dietary changes, medication or in some cases surgery.
osteomalacia found in adults while rickets is children.

3. Spinal disc herniation, and... I can't think of any more

I know that the Salter-Harris Fracture Classification System is national-level, but I wanted to include it anyway so...

Describe Types I-V in the Salter-Harris fracture classification system.

Describe Types I-V in the Salter-Harris fracture classification system.

Okay, answer! (Click to Show Hidden Text)

Type 1 - fracture breaks across the entire bone along the epiphyseal/growth plate. 
Type 2 - fracture breaks partially across the growth plate but breaks partly upward into the metaphysis
Type 3 - fracture breaks partially across the growth plate but breaks downward toward the epiphysis
Type 4 - fracture passes through epiphysis, metaphysis and growth plate.
Type 5 - fracture damages growth plate but does not displace. Usually b/c of direct compression.
