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.
