Study Notes
Structure of the Skeletal System
- The skeleton consists of major bones: cranium, clavicle, ribs, sternum, scapula, humerus, radius, ulna, carpals, metacarpals, phalanges, pelvis, vertebral column (cervical, thoracic, lumbar, sacrum, coccyx), femur, patella, tibia, fibula, tarsals, metatarsals.
- Bone classification includes long (leverage), short (weight-bearing), flat (protection), sesamoid (reduce friction), and irregular bones.
- Breakdown of skeleton:
- Axial skeleton: includes skull, vertebral column, and rib cage.
- Appendicular skeleton: includes limbs and their attachments to the body.
- Spine anatomy consists of curves that contribute to neutral spine alignment; common postural deviations include kyphosis (hunchback) and scoliosis (curvature).
- Bone growth involves osteoblasts (build bone), osteoclasts (break down bone), and the epiphyseal plate (growth plate).
Function of the Skeletal System
- Functions of the skeleton include:
- Support: providing a framework for the body.
- Protection: shielding vital organs.
- Muscle attachment: enabling movement through muscle-bone connections.
- Blood cell production: occurring in the bone marrow.
- Mineral storage: storing calcium and phosphorus.
- Leverage: facilitating movement by acting as levers.
- Weight bearing: supporting body weight during activities.
- Reducing joint friction: assisting movement efficiency.
- Different bone types function in specific ways during sporting actions:
- Long bones support leverage and red blood cell production.
- Short bones are crucial for weight bearing.
- Flat bones protect internal organs.
- Sesamoid bones minimize friction in joints.
Joints
- Joints in the upper skeleton include the shoulder, elbow, wrist, and cervical/thoracic vertebrae, facilitating a range of movements for various sporting techniques.
- Joints in the lower skeleton include the hip, knee, ankle, and lumbar/sacrum/coccygeal vertebrae, providing stability and mobility.
- Joints classification:
- Fibrous joints: fixed, do not move.
- Cartilaginous joints: slightly moveable.
- Synovial joints: freely moveable.
- Types of synovial joints include:
- Ball and socket (e.g., shoulder, hip).
- Condyloid (e.g., wrist).
- Gliding (e.g., carpals).
- Saddle (e.g., thumb).
- Hinge (e.g., knee, elbow).
- Pivot (e.g., neck).
- Understanding how different joints function is crucial for optimizing sports performance and reducing injury risk.
