Describe the difference between LMNs and UMNs, including an example of a disease affecting each.
What is the size principle of motor unit recruitment, and why is it important in locomotion?
Explain how a central pattern generator (CPG) can control locomotion without input from the brain.
Describe the myotatic (stretch) reflex and its clinical significance.
List and explain the functions of two UMN tracts important in animal locomotion.
Describe the role of the primary motor cortex (M1) in voluntary movement. How does it interact with other brain regions to execute complex movements?
Explain the function of the basal ganglia in movement control and give an example of a condition that results from its dysfunction.
What is the motor homunculus, and why do certain body parts, such as the hands and face, occupy a larger area of the motor cortex?
Discuss how repetitive practice of motor sequences leads to motor memory. How do athletes use mental imagery to enhance performance?
Compare the corticospinal tract and the rubrospinal tract in terms of their roles in voluntary movement.
