    Study Notes

    Appendicular Skeleton

    • The main role of the appendicular skeleton is to facilitate movement and support the body's appendages (limbs).

    Axial Skeleton

    • The axial skeleton mainly protects the central nervous system, including the brain and spinal cord.

    Skeletal System

    • The primary function of the skeletal system is to provide support, protection, and movement for the body.

    Bone Structure

    • Bone strength is contributed by the combination of organic and inorganic components.
    • Compact bones are dense and tough, making up 80% of the skeleton's weight.
    • Cancellous (spongy) bones are lightweight and porous, composed mainly of adipose cells.
    • Compact bones appear as solid masses.
    • Flat bones are thin and composed of two nearly parallel plates of compact bone enclosing a layer of spongy bone.

    Bone Marrow

    • Red bone marrow manufactures blood cells.
    • At birth, the marrow of all bones is red and functional, gradually becoming inactive in certain bones with age.

    Other Bone Types

    • Irregular bones cannot be categorized into any specific type, varying in amounts of spongy and compact bone.
    • Sesamoid bones develop in certain tendons that cross the ends of long bones in the limbs, protecting tendons from friction and wear.

    Bone Cavities

    • Bone marrow occupies the marrow cavity in long and short bones.
