Question

What aspects of movement are the pre-motor areas (PMAs) involved in?

a) Muscle coordination
b) Movement planning
c) Balance and posture
d) All of the above

Answer 1

The pre-motor areas (PMAs), consisting of the premotor cortex and supplemental motor area, are involved in movement planning, muscle coordination, and maintaining balance and posture.

Step-by-step explanation:

The pre-motor areas (PMAs) are involved in various aspects of movement. These areas, which include the premotor cortex and the supplemental motor area, are located adjacent to the primary motor cortex and play crucial roles in movement planning, controlling muscle coordination, and maintaining balance and posture during movement. Specifically, the premotor cortex helps manage the movements of core muscles to maintain posture, while the supplemental motor area is linked with planning and coordinating sequences of movements, particularly those that are learned and based on past experience.
