Questions and Answers

Why are movements inherently variable?

  • Because of the reliance on sensory feedback
  • Based on the adjustment of kinematic parameters
  • As a result of synergies between body parts
  • Due to large degrees of freedom (DOF) for most movements (correct)
  • What contributes to the achievement of motor coordination?

  • Reliance on proprioception and vision
  • Synergies between neuro-musculoskeletal elements
  • Adjusting kinematic and kinetic parameters associated with each body part (correct)
  • Modifications of sensory modalities

    Study Notes

    Motor Coordination in Physiology

    • Motor coordination refers to the ability to coordinate and control movements of body parts to achieve a specific goal or task.

    Factors Contributing to Motor Coordination

    • Sensory modalities, such as visual, auditory, and proprioceptive information, play a crucial role in achieving motor coordination.
    • Multisensory integration is essential for motor coordination, as it allows the integration of information from multiple sensory sources.

    Variability in Movements

    • Movements are inherently variable due to the dynamic interaction between the nervous system, the musculoskeletal system, and the environment.
    • The variability of movements allows for adaptability and compensation in response to changing environmental and internal conditions.
    • Actions and movements can be executed in multiple ways due to the redundancy and degeneracy of the motor system.

    Situations of Non-Repeatable Movements

    • Non-repeatable movements are often observed in novel or unfamiliar situations, where the motor system is still adapting to the new environment or task demands.
    • Non-repeatable movements may also occur in situations where there is a high degree of uncertainty or unpredictability, requiring rapid adaptation and flexibility.
