Question

which motor cortex should you stimulate to make the person coordinate multiple limbs to change their posture?
basal ganglia
cerebellum
premotor cortex
primary motor cortex
supplementary motor cortex

which motor cortex should you stimulate to make the person plan movements?
basal ganglia
cerebellum
premotor cortex
primary motor cortex
supplementary motor cortex

which motor cortex sends axons to the muscle groups in your body that cause them to contract and relax?
basal ganglia
cerebellum
premotor cortex
primary motor cortex
supplementary motor cortex

Explanation:

• For the first question: The supplementary motor cortex is involved in coordinating multiple limbs for posture - change. It helps in the sequential organization of movements across different body parts.
• For the second question: The premotor cortex is responsible for planning movements. It selects appropriate motor programs based on the goal of the movement.
• For the third question: The primary motor cortex sends axons (via the corticospinal tract) directly to the muscle groups to cause contraction and relaxation. It is the final common pathway for voluntary motor control.

Answer:

• First question: supplementary motor cortex
• Second question: premotor cortex
• Third question: primary motor cortex
