Sensory cells are specialized receptors that react to physical, chemical, and biological stimuli. They are responsible for our senses of sight, hearing, taste, smell, and touch. Synonyms for sensory cells include receptor cells, sensory receptors, sensory neurons, sensory organs, and sensory endings. Receptor cells are found in all organisms, from single-celled organisms to complex animals, and play a vital role in the functioning of the nervous system. Sensory receptors transmit signals to the brain, allowing us to perceive our environment and respond to stimuli. Understanding the different synonyms for sensory cells is important for knowledge of the nervous system and advancements in neurobiology and medicine.
