Role of the Skeletal, Muscular, and Nervous Systems in Movement Physiology

  • Skeletal System:

    • Provides structure and support

    • Serves as a framework for the body

    • Protects internal organs

    • Facilitates movement through joints where bones articulate

  • Muscular System:

    • Composed of muscles that contract and relax to produce movement

    • Muscles attach to bones via tendons

    • Work in pairs (agonist and antagonist) to enable motion

  • Nervous System:

    • Coordinates movement by sending signals from the brain to the muscles

    • Processes sensory information

    • Contributes to balance and coordination

Center of Gravity and Base of Support

  • The center of gravity for humans is typically located in the lower abdominal region or hip/pelvic area

  • Understanding the center of gravity is crucial during movement and lifting to minimize injury risk

  • Body position changes can shift the center of gravity, e.g., bending over with a cane can lower it to waist level

  • Improper management can increase the risk of falls or muscular strains

Conclusion

  • The interplay between the skeletal, muscular, and nervous systems is essential for:

    • Effective movement

    • Fall prevention

    • Reducing muscular strain in caregivers and patients
