Study Notes

Skeletal System

  • Composed of 206 bones
  • Axial skeleton: 80 bones (skull, vertebrae, ribs)
  • Appendicular skeleton: 126 bones (arms, legs, pelvic girdle)
  • Ligaments: Connect bone to bone, supporting joints
  • Tendons: Connect muscle to bone, enabling movement
  • Connective tissue: Provides structure and support to tissues and organs
  • Bone types: Long (femur, humerus), short (carpals, tarsals), flat (skull, ribs), irregular (pelvis, vertebrae)
  • Red bone marrow: Produces blood cells

Skeletal System Conditions

  • Sprain: Painful swelling/bruising around a joint, possibly with displacement
  • Osteoporosis: A condition with no symptoms; often associated with lack of exercise
  • Osteoarthritis: Breakdown of cartilage; results in deterioration
  • RICE: Rest, Ice, Compression, Elevation – a treatment for sprains and joint injuries
