In vertebrates, the olfactory receptors are located in both the cilia and synapses of the olfactory sensory neurons and in the epithelium of the human airway.In insects, olfactory receptors are located on the antennae and other chemosensory organs.ctivated olfactory receptors are the initial player in a signal transduction cascade which ultimately produces a nerve impulse which is transmitted to the brain.
The olfactory bulb is a part of the limbic system. Within the brain, the bulb is located in the forebrain, though in humans it sits at the bottom while in other vertebrates it sits at the very front. A bony structure called the cribiform plate cradles and protects it, and separates it from the nasal cavity.
