Sensory neurons are nerve cells responsible for transmitting information from sensory receptors in the body to the central nervous system. They are also known as afferent neurons or receptor neurons. Afferent neurons refer to sensory neurons because they carry information towards the central nervous system, while efferent neurons carry information away from it. Receptor neurons are another term used to describe sensory neurons because they have specialized receptors on their dendrites that detect stimuli. Some other synonyms for sensory neurons include input neurons, detection neurons, and peripheral sensory neurons. These terms reflect the function of sensory neurons in detecting environmental stimuli and transmitting that information to the brain for processing.
