emphasized

• Mechanisms of abnormal skeletal muscle contraction: usually ATP, electrolyte or neurotransmitter
• myoglobinuria (elevated myoglobin in urine) happens during a direct muscle injury
• partial dislocation is called a subluxation
• during compartment syndrome compression of blood vessels and nerves leads to necrosis and gangrene if no intervention
• a muscle strain happens during abnormal stretch of a muscle that is contracted
• a muscle sprain happens to a ligament or joint capsule
• type 1 osteoporosis: early post menopausal estrogen deficiency
• type II osteoporosis: due to calcium deficiency
• osteochondroses: due to decreased blood supply
• gout is a metabolic disorder that is due to increased levels of uric acid (causes pain!!)
