What is sensory transduction?

• A. The process of interpreting sensory stimuli
• B. Conversion of sensory stimuli into electrical impulses
• C. The act of responding to sensory information
• D. Transmission of impulses to the spinal cord

Answer: (B)

Sensory transduction refers to the process by which sensory receptors convert external stimuli—such as light, sound, or pressure—into electrical impulses that can be interpreted by the nervous system. This conversion is crucial because the nervous system predominantly processes information in the form of electrical signals. For instance, when light hits the photoreceptors in the retina, it causes a chemical change that ultimately results in the generation of an electrical signal that travels along the optic nerve to the brain. Similarly, when the skin is stimulated by touch, the mechanoreceptors transduce that physical pressure into electrical activity. This is the fundamental mechanism that enables the brain to receive and interpret varied sensory experiences from the environment. Understanding sensory transduction is vital in physiology because it underlies how we perceive and interact with the world around us. This concept is foundational in both sensory physiology and neurobiology, illustrating the intricate processes involved in detecting and responding to environmental stimuli.
