Examples of different types of joints in the human body (ball-and-socket, hinge).

📚 Quick Study Guide

• 🦴 Joints: Locations where two or more bones connect.
• ⚙️ Types of Joints: Classified by structure (fibrous, cartilaginous, synovial) and function (immovable, slightly movable, freely movable).
• ⚽ Ball-and-Socket Joint: Allows movement in multiple axes; examples include the hip and shoulder.
• 🚪 Hinge Joint: Permits movement in one plane; examples include the elbow and knee.
• 🤸 Range of Motion (ROM): Refers to the extent of movement a joint can achieve. Factors influencing ROM: joint structure, ligaments, tendons, muscles, and overall health.
• 💪 Synovial Joints: Characterized by a joint cavity filled with synovial fluid, providing lubrication and nutrients.
• ⚕️ Common Joint Injuries: Include sprains (ligament damage), strains (muscle/tendon damage), and dislocations (bone displacement).
