WebThe receptor cells are bipolar type sensory neurons (with one axon and one dendrite); some of them have a ciliate distal end and others have a distal end with microvilli. The axons of these olfactory receptor neurons form the olfactory nerve (I) that reaches the olfactory bulb in the telencephalon. WebThe olfactory receptor neurons are located in a small region within the superior nasal cavity (see Figure 4.1.1 below). This region is referred to as the olfactory epithelium and contains bipolar sensory neurons.

WebFeb 20, 2024 · Sensory neurons (sometimes referred to as afferent neurons) are nerve cells that carry nerve impulses from sensory receptors towards the central nervous system and brain. When these nerve impulses reach the brain, they are translated into ‘sensations’, such as vision, hearing, taste, and touch. WebJan 17, 2024 · Taste stimuli are encountered by receptor cells located in taste buds on the tongue and pharynx. Receptor cells disseminate onto different neurons and convey the message of a particular taste in a single medullar nucleus. Taste perception is created by combining multiple sensory inputs.
