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:
1. Support & protection
2. Lever
3. Point of attachment
4. 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
• Hinge Joint– Allows movement
forward and backward
• Pivot Joint– Allows for rotating
motion
Types of Joints: Ball & Socket Joint and the Gliding Joint
• Ball & Socket– Allows movement in
any direction
• Gliding Joint– Allows for movement
of bones past one another

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 Smooth -Involuntary-Diaphragm, Digestive Tract
Cardiac Striped -Involuntary-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
