A sensory receptor is a sensory nerve ending that responds to a stimulus in the internal or external environment of an organism. The sensory receptor initiates sensory transduction by creating graded potentials or action potentials in the same cell or in an adjacent one.
The sensory receptors for the eyes are the optic nerve and the retina. The sensory receptor for the nose are the olfactory nerves.
An organ that contains receptor cells is called a sensory organ. These organs perceive external stimuli such as light, sound, touch, taste, and smell and transmit this information to the brain for processing.
The main sensory receptor in the ear is the hair cells located in the cochlea. These hair cells convert sound waves into electrical signals that are then transmitted to the brain via the auditory nerve, allowing us to perceive sound.
Eyes: The sensory receptor in the eyes is the photoreceptor cell, specifically the rods and cones, which detect light and color. Nose: The sensory receptor in the nose is the olfactory receptor, located in the olfactory epithelium, which detects odor molecules. Tongue: The sensory receptors in the tongue are taste buds, which contain taste receptor cells that detect different tastes like sweet, salty, bitter, sour, and umami. Skin: The sensory receptors in the skin include mechanoreceptors (detect touch and pressure), thermoreceptors (detect temperature), nociceptors (detect pain), and proprioceptors (detect body position and movement).
The olfactory receptor cells in the nose are the only sensory receptors that can be replaced throughout life. This neurogenesis allows for the continual renewal of these cells to help maintain our sense of smell.

Sensory receptor cells
The sensory receptor for smell is called the olfactory receptor. These receptors are located in the olfactory epithelium in the upper part of the nasal cavity and are responsible for detecting and transmitting odors to the brain for interpretation.
Adaptation of nerve cells in simple sensory receptors can be seen in how they respond differently to constant stimuli over time. For example, in a pressure receptor in the skin, the nerve cells may initially fire rapidly in response to pressure but then slow down as they adapt to the constant pressure stimulus.
A Sensory Receptor is a cell within the peripheral nervous system that gathers information from the environment and from inside your body. Answer from: Science Textbook! I Hope I Helped You!
The sensory receptor for the eyes is the photoreceptor cells located in the retina. There are two main types of photoreceptors: rods, which are sensitive to low light levels and help with night vision, and cones, which are responsible for color vision in bright light.
