Sensory nerves (afferent peripheral nerves)

Electric signal (action potentials) from the receptors reach the central nervous system via the sensory nerves (afferent peripheral nerves).

The receptors convert stimuli, such as light, into electric signal (action potentials).

Receptors, such as the (retina of the) eye convert light into electric signal (action potentials). For this to be 'seen', it has to reach the cerebrum, which is a part of the central nervous system).

Electric signal (action potentials) from the receptors, such as the eyes, reach the central nervous system via the sensory nerves (afferent peripheral nerves).

Electric signal (action potentials) from the receptors reach the central nervous system via the {=sensory nerves (afferent peripheral nerves) ~motor nerves (efferent peripheral nerves)}.
