Skeletal System

The Human Skeleton

Skeletal System - a body system made up of bones, joints and connective tissues.
Marrow - a soft tissue in the center of some bones.

Connecting Parts

Cartilage - A strong, flexible, gel like tissue that cushions your joint.
Tendons - Connect Muscles to bones.
Ligaments - Connect Bones to Bones.

Your skeletal system allows you to move.
There are 206 bones in the human body. A newborn has 350 bones.

What the Skeletal System helps?

Supports the body by providing a framework for the body.
Protects the internal organs. Example: Rib cage protects your heart and lungs.
Stores Minerals. Example: Calcium and phosphorus.
Makes blood cells in the bone Marrow.

Common Name for each Bone

Phalanges

Tibia = Shin Bone
Clavicle = Collarbone
Vertebrae = Spine/Backbone
Femur = Thigh
Mandible = Jaw
Scapula = Shoulder Bone
Humerus = Arm
Patella = Kneecap
Pelvis = Hip
Cranium = Skull
Phalanges = Fingers and Toes

Joints

Joints is the point where to bones meet. Your fingers are a great example of joints, the so "cracking knuckles" is pulling away your joints.

Immobile, Slightly Immobile, and Mobile Joints

Immobile

Immobile joints are joints that can't move.

Examples are the Skull and Cranium.

Slightly Immobile

Slightly Immobile joints are joints that permit slight movement.

Examples: Between the vertebrae of the back.

Mobile

Mobile joints are joints that permit wide movement joints.

Examples: Fingers

Connective Tissues

Connective tissue is a strong, flexible tissue that cushions joints.

Tendons - connect muscles to bones.
Ligament - connect bones to bones.

Sprains/Diseases in relation with the Skeletal System

Fractures - A break in a bone caused by an injury.
Dislocations - When a bone is pushed out of its joint.
Sprain - Stretching or twisting of ligaments. (Full definition: Ligaments are short parts of tough, flexible connective tissues that connects two bones, or cartilages, or holds together a joint)
Overuse - Injuries - occurs over time.
Scoliosis - A disorder where the spine curves in a "C" or "S" like curve/shape.
Osteoporosis - A disease where the bones are brittle.

Taking care of your skeletal system

A. Good Diary products contain calcium, phosphorus, magnesium, and Vitamin D. These vitamins help with the strenghtening of bones.
B. Regular Exercise: Increases Bone Mass.
C. Good Posture helps keep the spine healthy/in balance.
D. Take time to heal: Wait for it to be completely heal before returning back into physical activity.
E. Use protective gear when doing physical activities, such as riding your bicycle.
