Retina
The olfactory epithelium, located in the upper part of the nasal cavity, holds the olfactory receptor cells responsible for detecting smells. It contains specialized nerve cells that send signals to the brain when they detect specific odor molecules.
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.
Receptor molecules
Yes, target cells possess specific receptor molecules on their surface that bind to signaling molecules such as hormones or neurotransmitters. This interaction triggers a cellular response or change in function within the target cell, influencing various physiological processes within the body.
The outer part of a G protein-coupled receptor (GPCR) binds to ligands, such as hormones or neurotransmitters, which activates the receptor. The inner part of the receptor interacts with and activates a G protein, initiating downstream signaling cascades within the cell.
Transduction occurs in the retina of the eye. The retina contains specialized cells called photoreceptors (rods and cones) that convert light signals into electrical signals, which are then transmitted to the brain via the optic nerve for visual processing.
The receptor cells located in your tastes buds send messages through sensory nerves to your brain. Your brain then tells you what flavors you are tasting.

The olfactory membranes are located in the upper part of the nasal cavity and contain olfactory receptors responsible for detecting odor molecules. These receptors send signals to the brain, allowing us to perceive different smells.
No. The nucleus is the part of the cell that holds the DNA. Plant cells have a nucleus, but a nucleus by itself is not a cell.
