7. Urinary tract infections-A UTI or urinary tract infection can affect any part of the urinary tract. Germs inside the urinary system can cause fever, pain, cramping, cloudy urine, and feeling the need to urinate, even when the bladder is empty.
The sensory receptors involved in taste and smell contain receptor molecules that bind to specific chemicals.Odor receptors in olfactory receptor neurons, for example, are activated by interacting with molecular structures on the odor molecule.Similarly, taste receptors (gustatory receptors) in taste buds interact with chemicals in food to produce an action potential.dor receptors in olfactory receptor neurons, for example, are activated by interacting with molecular structures on the odor molecule. Similarly, taste receptors (gustatory receptors) in taste buds interact with chemicals in food to produce an action potential.
How the sense of smell works. The sense of smell, just like the sense of taste, is a chemical sense. They are called chemical senses because they detect chemicals in the environment, with the difference being that smell works at dramatically larger distances than that of taste. The process of smelling goes more or less like this:
