Splh 620 exam 3 q - Study guides, Class notes & Summaries

What are the three most important motor cortical areas? - ANSWER-1. Primary motor 2. Premotor 3. Supplementary motor What is the pathway of the Spinal Motor Pathway? - ANSWER-—Upper motor neurons 1. Cerebral cortex to spinal cord 2. Descend through the internal capsule 3. Decussates in medulla (brainstem) 4. Synapse in anterior horn of spinal cord: Corticospinal tract 5. Does not go through thalamus —Lower motor neurons 6. Cell body in anterior horn of SC 7. Synapse with musc...

Motor control structures - ANSWER-cerebrum, brainstem, spinal cord, cerebellum, thalamus, basal ganglia, motor nerves/neurons, muscle fibers Motor control overview - ANSWER-Begins with CNS, ends with muscles, CNS contains two types of neurons (upper motor neurons [cerebrum], lower motor neruons [brainstem, spinal cord]), can perform complex voluntary behavior and reflexes Spinal motor pathway - ANSWER-Upper motor neurons and lower motor neurons Spinal motor pathway upper motor neurons -...
