Facts
Facts

  • 350 bones at birth

  • 206 bones as an adult


Functions
Functions

  • Provide stable framework which aids in the protection of internal organs.

  • Storage of minerals like calcium and phosphorus.

  • Manufacture red blood cells as well as some of the white blood cells


Axial skeleton
Axial skeleton

  • Axial skeleton

    -Skull, spine, ribs and sternum (breastbone).

  • Appendicular skeleton

    -Includes hands, feet, arms, legs, shoulders and hips


Types of bones
Types of bones

  • Short bones

    -Bones found in the wrist and ankles.

  • Long bones

    -Bones found in the arms and legs.

  • Flat bones

    -Bones found in the skull, hips, ribs and shoulder blades

  • Irregular bones

    -Bones found in the vertebrae.


Cartilage
Cartilage

- Flexible connective tissue that adds protection between the joints and gives shape to certain parts of the body like the ears and nose.


Types of joints
Types of Joints

  • Ball and socket joint

    -Found in the shoulders and hips

  • Hinge joint

    -Found in the fingers, toes, knees and elbows

  • Ellipsoidal joint

    -The group of bones that make up the wrist and ankles.

  • Pivot joint

    -The joint that sits at the top of the spine(vertebrae) and allows the skull to pivot sideways and move up and down.


Connective tissues
Connective tissues

  • Ligaments

    - Strong fibrous bands that connect bone to bone.

  • Tendons

    - Strong fibrous cords that hold muscle to muscle or muscle to bone.


Fractures
Fractures

  • Hairline- small crack in the bone usually from repetitive motion

  • Complete or transverse- bone is broken all the way across the bone

  • Comminuted or shattered- bone crushed into many pieces

  • Spiral- bone broken in a spiral fashion from twisting of limb.

  • Compound- bone breaks and sticks out of the skin.


Problems with skeletal system
Problems with Skeletal System

  • Osteoporosis

    -Loss of bone mass from poor nutrition or could be part of the aging process.

  • Scoliosis

    -Bones become soft or weak and tend to curve. Often found in the spine.


Joint injuries
Joint injuries

  • Dislocation-bone skips from normal position

  • Torn cartilage- result from sharp blow or severe twisting

  • Bunion- swelling of the bursa in first joint of big toe

  • Bursitis- Bursa in any joint becomes inflamed

  • Arthritis- inflammation of a joint, characterized by pain, swelling, stiffness, and redness
