During which phase are sensory impulses conducted to the spinal cord?

The phase during which sensory impulses are conducted to the spinal cord is known as transmission. In this phase, the neural signals that have already been generated from sensory receptors are carried through the peripheral nerves to the central nervous system. This involves the propagation of action potentials along afferent nerve fibers, which transmit information about the sensory stimuli (such as pain, temperature, or touch) to the spinal cord.

Transmission is essential because it serves as the conduit for sensory information to reach the brain for further processing. This phase follows transduction, where the initial energy from a stimulus is converted into an electrical signal by sensory receptors. While modulation refers to the processing and alteration of these signals within the nervous system, and perception involves the conscious interpretation of those signals in the brain, transmission specifically encompasses the journey of these impulses to the spinal cord.
