What is a chemosensory organ?
What is a chemosensory organ?
Chemosensory organs are also important sites of information processing. Environmental stimuli are encountered at these structures, and these signals are interpreted in sensory cells before being passed on to higher levels of the nervous system.
What is chemosensory function?
Understanding normal chemosensory function helps clarify the molecular events that underlie taste and smell disorders. At least 2,000,000 Americans suffer from chemosensory disorders–a number that is likely to grow as the aging segment of the population increases.
What are the two chemosensory systems?
Two different chemosensory systems are incorporated in the olfactory epithelium: olfactory sensory neurons proper and solitary chemosensory cells comprised of secondary sensory cells innervated by the trigeminal nerve.
What is chemoreception and its function?
chemoreception, process by which organisms respond to chemical stimuli in their environments that depends primarily on the senses of taste and smell. Chemoreception relies on chemicals that act as signals to regulate cell function, without the chemical necessarily being taken into the cell for metabolic purposes.
What is an example of Mechanoreceptor?
n. a receptor that is sensitive to mechanical forms of stimuli. Examples of mechanoreceptors are the receptors in the ear that translate sound waves into nerve impulses, the touch receptors in the skin, and the receptors in the joints and muscles (see proprioceptor).
Where are chemosensory cells located?
Solitary chemosensory cells (SCCs) (also called solitary chemoreceptor cells) are isolated elements located in epithelia of the apparatuses of endodermic origin (such as respiratory and digestive apparatuses). In the aquatic vertebrates, SCCs are also present in the skin.
What is a chemoreceptor example?
Two main classes of chemoreceptors are direct and distance. Examples of direct chemoreceptors are taste buds, which are sensitive to chemicals in the mouth, and the carotid bodies and aortic goodies that detect changes in pH inside the body.
What is Chemesthetic?
Chemesthesis is defined as the sensitivity of mucosal surfaces to environmental chemicals. Activation of this system elicits thermal, nociceptive, and tactile sensations. In the oral cavity, mucosal surfaces respond to compounds found commonly in foods and the evoked sensations contribute to the overall flavor percept.
