Locomotion

Locomotion Movement! The interaction between endoskeleton and muscles Endoskeleton: Skeleton is on the inside Exoskeleton: Skeleton is on the outside

The Human Skeleton Purpose: Support & protection Lever Point of attachment Blood cell production

Joint An area where two bones meet Allows for movement

Types of Joints: Suture Joint Where the skull bones meet Very small amount of movement allowed

Types of Joints: Hinge Joint & Pivot Joint Allows movement forward and backward Pivot Joint Allows for rotating motion

Types of Joints: Ball & Socket Joint and the Gliding Joint Allows movement in any direction Gliding Joint Allows for movement of bones past one another

A. B. C. D. E.

Examples of Joints Suture Hinge Pivot Ball & Socket Gliding

Muscle- tissue used for movement Type of Muscle Appearance Function Skeletal Striped Voluntary Arms, legs, toes, fingers Smooth Involuntary Diaphragm, Digestive Tract Cardiac Heart

Ligaments & Tendons Ligaments Connect bones to bones Tendons Connect muscle to bone

Cartilage Purpose: Support Flexibility Cushioning It does NOT anchor Found in the outer ear, nose, between back bones

Malfunctions Malfunction Location Cause Symptoms Cure Tendonitis Elbow Less likely in hip or torso Swelling of tendon - Aches, pains, stiffness Stop usage Anti-inflammatories Braces Sprain - Ankle, knee, wrist, fingers, toes Overextension of ligaments - Pain, swelling, bruising - Rest, ice, compression, elevation
