    Study Notes

    Classification of Bones

    • Bones are categorized based on shape rather than size.

    Long Bones

    • Characterized by a long shaft and two ends.
    • Typically found in the appendicular skeleton.
    • Examples include femur, humerus, and phalanges.

    Short Bones

    • Cube-shaped bones that provide stability and support.
    • Commonly located in the appendicular skeleton.
    • Examples include carpals (wrist bones) and tarsals (ankle bones).

    Flat Bones

    • Have a thin and flat structure, offering protection and extensive surface area for muscle attachment.
    • Predominantly located in the axial skeleton but can also be found in the appendicular skeleton.
    • Examples include the pelvis (ilium), sternum, ribs, and various skull bones (frontal, parietal, occipital).

    Irregular Bones

    • Have complex shapes that do not fit into other classifications.
    • Provide support and protection while allowing flexibility.
    • Examples include vertebrae and zygomatic bones (cheekbones).
    • All bones except for the Achilles tendon are connected to other bones.

    Sesamoid Bones

    • Small, seed-shaped bones that form within tendons.
    • Help reduce friction and improve mechanical advantage.
    • The patella (kneecap) is a primary example.

    Anatomy of a Long Bone

    • Hyaline Cartilage: Smooth tissue that covers bone surfaces at joints, facilitating movement.
    • Cartilage: Flexible connective tissue found in various forms, including in articulating surfaces.
    • Epiphysis: The ends of a long bone, important for joint function and bone growth.
    • Diaphysis: The long tubular shaft of the bone that houses the marrow cavity.
