Question

The primary motor cortex is not connected to the spinal cord, but instead information is passed through many different areas in the brain. Discuss how commands are generated in cortex, including different areas involved, and how they are eventually relayed to the spinal cord to control the somatic system. To answer the question select a specified outcome behavior like riding a bike or driving a car and use that to discuss the generation of required activity and the pathway, including possible feedback signals to generate a more precise motor command

Answer 1

Rising a motor bike or car is a type of reflections action that rely on the action of both brain and spinal cord. In humans most sensing neurons can't pass directly into the brain rather then in the synapse of spinal cord. This causes activation of spinal motor neurons without delay of routine signals through the brain this causes reflex actions occur faster . The brain will receive the sensory input while the reflex being carried out and analysis of the signal takes place after the reflex action.

So the pathway is 1. Sensory nerve carry information from receptor to spinal cord, 2. And then carry the response generated by spinal cord to effector organ.
