list the functionally homologous muscles in the front and hind limbs - that is, which muscles perform the same function. Include a description of an action that would require flexion of both elbow and knee. What is one muscle responsible for each of these movements, and how does it do it? Describe an action that would require extension of both elbow and knee. What is one muscle responsible for each of these movements, and how does it do it?

1: A. You are jogging and your lower limbs are constantly sending sensory position/proprioceptive info to your cerebellum, and your cerebellum is sending output to your primary motor cortex, which then modifies your Lateral Corticospinal tract. This makes a spinal cord-cerebellum-cerebrum-spinal cord“loop” to control your leg muscles. List all the structures, tracts, nuclei, decussations, cells, etc to describe this loop. Start with afferent spinal nerves from the legs. B. You are on the field, about to kick the winning field...
