The human body's ability to perceive and respond to the environment hinges on the diverse structures of sensory receptors, which are classified based on their cellular composition. These receptors, depicted in this image, include neurons with free nerve endings, encapsulated nerve endings, and specialized cells like photoreceptors, each playing a unique role in sensory processing. This article provides an in-depth exploration of these receptor types, their anatomical features, and their critical functions in translating external stimuli into neural signals.
