    Study Notes

    Skeletal System Functions

    • Protection of internal organs is crucial in situations like car accidents.
    • Bone tissue is dense, hard connective tissue integral to the skeletal system.

    Bone Marrow and Blood Production

    • Red marrow is essential for blood cell production; its absence halts this function.
    • Yellow marrow serves as a fat storage area.

    Types of Bones

    • The skeletal system consists of bones and cartilage.
    • Long bones dominate the skeleton; however, the bones in the wrist are considered short bones.
    • Sesamoid bones are embedded within tendons.

    Bone Classifications

    • Irregular bones protect the spinal cord, while long bones facilitate movement by acting as levers.
    • Cancellous bone is where hematopoiesis occurs, and trabeculae are only found in this area.

    Bone Structure and Development

    • Diaphysis contains fat stores; periosteum is the fibrous membrane covering bone surfaces.
    • Osteoblasts and osteocytes do not replicate due to their essential functions and origins.

    Bone Growth and Repair

    • Endochondral ossification leads to chondrocyte death, forming the medullary cavity.
    • Intramembranous ossification primarily forms flat bones in the cranium.
    • Bone growth occurs at the epiphyseal plate for length and beneath the periosteum for diameter.

    Fractures and Healing Process

    • Fractures can be both open and transverse, and may release fat globules from damaged yellow marrow.
    • Compound fractures pierce the skin, and healing begins with spongy bone formation, shifted towards trabecular bone.

    Hormonal Influence on Bones

    • Wolff's law demonstrates how mechanical forces influence bone remodeling based on activity patterns.
    • Calcium absorption is influenced by vitamin D, and hormonal balance is maintained by calcitonin and parathyroid hormone.

    Axial Skeleton Features

    • The axial skeleton supports the trunk and includes key structures such as the vertebral column and cranial bones.
    • Parietal bones are part of the braincase; the lambdoid suture connects parietal and occipital bones.

    Vertebral Column and Ribs

    • The cervical region has seven vertebrae; primary curvatures relate to fetal development.
    • True ribs articulate directly with the sternum, while endochondral ossification forms the axial skeleton.

    Upper and Lower Limb Anatomy

    • The shoulder involves the acromioclavicular joint; the clavicle articulates with the manubrium.
    • The hip bone consists of three fused bones; ilium forms the superior part, ischial tuberosity supports body weight.

    Joints Classification and Types

    • Joints include amphiarthrosis between vertebrae, synarthrosis at the manubriosternal joint, and biaxial diarthrosis at the metacarpophalangeal joint.
    • Synovial joints have a fluid-filled cavity, while specific types like syndesmosis connect fibula and tibia.

    Bursa and Joint Functionality

    • Bursae reduce friction between structures, while synovial membranes secrete lubricating fluid essential for joint function.

    Motion and Range

    • Ball-and-socket joints provide the widest range of motion, unlike hinge joints that allow uniaxial movement.
