Control of Wrist and Arm Movements at Varying Difficulties

This week's article is focused on "Control of Wrist and Arm Movements at Varying Difficulties" by Jason Boyle. Our muscles are controlled by “motor units”, which each consist of a neuron, and the muscle fiber(s) it activates or “innervates”. The muscle that responds is termed an “effector”. Brain mapping studies have shown that a disproportionate area of the motor cortex governs certain effectors of the body.
