All three structures are involved in the process of picking up a dime. The sensory receptors in the hand send a signal to the spinal cord, which in turn sends a signal to the brain. The brain then sends a signal back through the spinal cord to the muscles in the hand, causing them to contract and pick up the dime. Together, the spinal cord, peripheral nervous system, and afferent and efferent neurons all contribute to this process.
