Nerve endings that receive stimuli and transmit impulses to the brain for interpretation (perception). There are five such 1. touch, temperature, pressure, pain; 2. smell, odors; 3. taste; 4. sight; and 5. hearing.
Collection of specialized cells receptor cells —capable of responding to a particular stimulus (e.g., an odor) and transmitting that message as an impulse along a sensory nerve to the central nervous system for interpretation.
A collection of specialized cells (receptors), connected to the nervous system, that is capable of responding to a particular stimulus from either outside or inside the body. Sense organs can detect light (the eyes), heat, pain, and touch (the skin), smell (the nose), and taste (the taste buds).
A sensory receptor; a structure consisting of specialized sensory nerve endings that are capable of reacting to a stimulus (an external or internal change) by generating nerve impulses that pass through afferent nerves to the central nervous system. These impulses may give rise to sensations or reflexly bring about responses in the body.
