# Skeletal System The skeletal system is comprised of two parts: * **Axial Skeleton:** 80 bones (skull, vertebrae, ribs) * **Appendicular Skeleton:** 126 bones (arms, legs, pelvic girdle) ## Components and Functions * **Ligaments:** Connect bone to bone, providing joint stability. * **Tendons:** Connect muscle to bone, aiding in movement of extremities. * **Connective Tissue:** Provides structure and protection to tissues and organs. * **Bone Types:** * **Long Bones:** Femur, humerus, tibia, fibula, ulna, radius * **Short Bones:** Carpals, tarsals * **Flat Bones:** Skull, ribs * **Irregular Bones:** Pelvis, vertebrae * **Red Bone Marrow:** Produces new blood cells. ## Conditions * **Sprain:** Painful swelling or bruising of a joint area; the joint is pushed out of its normal range of motion. Diagnosis involves a physical exam and imaging. * **Osteoporosis:** A condition with no symptoms, but may lead to immobilization and lack of excessive exercise. Diagnosis involves a history, physical exam, and imaging. Treatment can include physical therapy, exercise, and steroid injections. * **Osteoarthritis:** Break down of cartilage. This leads to degeneration of articular cartilage. Diagnosis involves a history, physical exam, and imaging, and treatment might include physical therapy, exercise and steriod injections to help relieve. **Note:** The information provided above is extracted from the handwritten/typed notes.
