Verified step by step guidance

Understand the role of sensory receptors: Sensory receptors are specialized cells or structures that detect changes in the environment and convert these changes into electrical signals that can be interpreted by the nervous system.

Identify the location of sensory receptors: Sensory receptors are not limited to the central nervous system. They are found throughout the body, including in the skin, eyes, ears, nose, and tongue, where they detect various stimuli such as light, sound, touch, and chemicals.

Clarify the function of sensory receptors: Sensory receptors are responsible for converting external stimuli, such as light, sound, or pressure, into electrical signals. This process is known as transduction.

Differentiate sensory receptor functions: While some sensory receptors are specialized to detect pain and temperature changes, others are designed to detect different types of stimuli, such as light (photoreceptors), sound (mechanoreceptors), or chemicals (chemoreceptors).

Conclude with the correct statement: Based on the understanding of sensory receptors, the statement 'They convert external stimuli into electrical signals' accurately describes their primary function.
