    Study Notes

    Skeletal System Overview

    • The skeleton consists of 206 bones that provide support, protection, and movement for the body.
    • At birth, the human skeleton has around 300 bones, which fuse together as we grow and develop.

    Axial Skeleton

    • The axial skeleton consists of the skull, vertebrae, ribs, and sternum.
    • The lumbar region of the spine forms the lower back.
    • The first seven ribs are called true ribs.
    • The coccyx is formed by 3-5 fused vertebrae.

    Vertebral Column

    • The atlas is the first bone of the cervical spine.
    • The sacrum connects the spinal column to the pelvic girdle.

    Functions of the Skeleton

    • The skeleton provides support, protection, movement, and blood cell production.
    • The exoskeleton is the term for the skeleton that is on the outside of the organism.
    • The skeleton does not produce hormones.

    Connective Tissues

    • Ligaments connect bones to each other and provide stability to joints.
    • Synovial fluid in joints reduces friction and allows for smooth movement.
    • Ball-and-socket joints allow movement in all planes.

    Bone Structure and Function

    • Tendons connect muscles to bones and facilitate movement.
    • The growth plate is responsible for bone growth and development.
    • The periosteum is a layer of tissue that covers the bone and allows for bone growth and repair.
    • Compact bone is composed of tightly packed osteons.
    • Cartilage is composed primarily of collagen and chondroitin sulfate.

    Joint Disorders

    • Arthritis is caused by inflammation of the joints.
