What are smaller motor units used for?Multiple choice question.Strength and powerFine motor controlPostural musclesCoarse motor control

Smaller motor units are primarily used for:

Analysis

1. Fine Motor Control: Smaller motor units consist of fewer muscle fibers innervated by a single motor neuron, allowing for precision in movements. This is crucial for tasks that require high accuracy, such as typing or playing a musical instrument.

2. Strength and Power: Larger motor units, not smaller ones, are typically associated with strength and power because they recruit more muscle fibers for greater force output.

3. Postural Muscles: While postural muscles are important for maintaining stability, they usually involve both smaller and larger motor units based on the need for fine adjustments versus overall stability.

4. Coarse Motor Control: Coarse motor control involves larger movements and generally utilizes larger motor units for greater overall strength rather than the precision provided by smaller motor units.

Final Answer

Fine motor control
