Synovial Joints • Freely movable joints that permit movement in one or more directions • 5 common types of synovial joints: • Ball and Socket joints • Hinge joints • Pivot joints • Saddle joints • Gliding joints
Types of Movement • Flexion – the angle of the joint is decreased. • Extension – the angle of the joint is increased. • Abduction – a body part is moved away from the middle of the body. • Adduction – a body part is moved towards the middle of the body. • Rotation – a body part is moved either outwards or inwards around its long axis.
Types of Movement • Supination – a rotation of the forearm which causes the palm of the hand to face upwards. • Pronation – a rotation of the forearm which causes the palm of the hand to face downwards. • Inversion – a rotation of the sole of the foot inwards. • Eversion – a rotation of the sole of the foot outwards.
Tendons, Ligaments, & Cartilage • Tendons • Connect muscle to bone • Strains • Ex. Achilles tendon & biceps tendon • Ligaments • Connect bone to bone • Sprains • Ex. ACL, MCL, LCL, PCL, and ankle ligaments • Cartilage • Use for cushioning of joints • Ex. Meniscus and Labrum
