    Study Notes

    Bone Classification

    • Bones can be classified by shape, region, and structure.
    • Shape: Long, short, flat, irregular, and sesamoid
    • Region: Axial (bones of the midline and trunk) and appendicular (bones of the limbs, including the girdles)
    • Axial skeleton is green, appendicular skeleton is pink.

    Skeletal System

    • The skeletal system is made up of bones & cartilage, joined together by joints.

    Bone

    • Bone is a special type of connective tissue with a calcified matrix.
    • It consists of cells, fibers, and a matrix.

    Bone Functions

    • Support: Provides framework for the body
    • Protection: Protects vital organs
    • Movement: Allows for movement with muscles
    • Storage of Minerals: Stores calcium and phosphorus
    • Production of blood cells: Red bone marrow produces blood cells

    Vertebrae

    • Vertebrae are bones of the spine.
    • There are 7 cervical, 12 thoracic, 5 lumbar, 5 fused sacral, and 4 fused coccygeal vertebrae.
    • Each vertebra has a body (anteriorly), a vertebral arch (posteriorly) made up of pedicles & laminae, transverse processes (laterally), and spinous processes (posteriorly).

    Sacrum & Coccyx

    • The sacrum is formed by 5 fused vertebrae.
    • The coccyx is formed by 4 fused vertebrae.

    Thoracic Cage

    • The thoracic cage is formed by the sternum and ribs.
