Skeletal System Mr Oles Focus on these bones

Skeletal System Mr. Oles

• Focus on these bones • Cranium, clavicle, scapula, sternum, ribs, pelvis, femur, patella, vertebra, humerus, ulna, tibia, fibula, radius, carpals, tarsals

5 Functions of the Skeletal System • WHAT ARE THEY? !!!

5 Functions Are? ! • Provide Shape and support • Allows Movement • Protects Tissues and Organs • Stores Certain Materials • Produces Blood Cells

Development of Bone • Most bones are formed from cartilage A. Cartilage acts as padding between bones

Structure of Bones • Inside the bones is a hollow space full of a material called marrow – Marrow contains fat and produces blood cells

Skeletal Joints The four types of joints are pivot, Hinge, ball-and-socket, and gliding

Skeletal Joints • Pivot joints allow rotation of one bone around another

Skeletal Joints • Ball-and-Socket Joints provide for circular motion

Skeletal Joints • Hinge Joints allow forward and backward movements but little side to side

Skeletal Joints • Gliding Joints allow one bone to slide over another

Connectors? ! • Ligaments connect bones to bones and restrict unhealthy movement • Tendons connect muscles to bones

OHH NO!!! • Torn ACL! • What Happens!

• 1: What bone or bones is/are broken? 2: For this bone what is its main function (of the five main purposes of the skeletal system)? • 3: Describe the problem with the bone (fracture, dislocation)
