Bones: Living or Dead?Bones: Living or Dead?• Living!!!
– Living tissue composed of cells. – Bone cells need food and oxygen to grow,
strengthen, work, and repair themselves.

Importance of Skeletal System?Importance of Skeletal System?• Movement
– Provide points of attachment for muscles. • Our body can only move because our muscles
pull on our bones, which then moves our body.

Importance of Skeletal System…Importance of Skeletal System…• Support
– Vertebrae• Supports your head and upper body and
protects your spinal cord• Without your skeletal your body would collapse
into a heap on the floor.

– Bones of skull protect brain– Ribs protect heart and lungs from injury

Importance of Skeletal System…Importance of Skeletal System…• Blood Cell Formation
– Provide red and white blood cells• Marrow is the tissue that produces these cells
inside the center of the bone

• Storage– Bones store minerals (calcium, phosphorus)
for use when needed by your body.

JointsJoints• Hinge Joints
– Elbows and Knees• Moves in only one direction

JointsJoints• Gliding Joints
– Wrists and ankles– Enable bones to slide over one another– Not great range of motion

JointsJoints• Pivot Joints
– Between neck and head– Moves from side-to-side and up and down– Rotates on an axis (off your neck)– Limited range of motion to the side

JointsJoints
• Ball-and-socket Joints– Hips and shoulders– Move in all directions– Shoulder has greatest range of motion– Bone fits in tight and secure into socket– Extremely painful when dislocated

• Cartilage– Tough, flexible tissue similar to bone. Acts
as a cushion between bones at a joint and protects the bones.
• Prevents the bones from rubbing together and wearing down the bone.
• Between your vertebrae there is cartilage.• Knee contains cartilage.• Nose and ears made of cartilage.

Connectors in the BodyConnectors in the Body• Ligaments
– Strong cords of tissue that connect bones at the joints.
– They hold the bones in place!
