Sensory Receptors One of the characteristics of a living organism is its ability to respond to stimuli. The human sensory  system is highly evolved and processes thousands of incoming messages simultaneously. This  complexity allows you to be aware of your surroundings and take appropriate actions. Sensory receptors are dendrites of sensory neurons specialized for receiving specific kinds of  stimuli. Sensory receptors are classified by three methods:  Classification by receptor complexity: Free nerve endings are dendrites whose terminal ends have little or no  physical specialization. Encapsulated nerve endings are dendrites whose terminal ends are enclosed  in a capsule of connective tissue. Sense organs (such as the eyes and ears) consist of sensory neurons with  receptors for the special senses (vision, hearing, smell, taste, and equilibrium)  together with connective, epithelial, or other tissues. Classification by location:
