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.
Smell results when individual molecules, suspended in the air, are inhaled and attach to receptors in the mucous membranes of the nose, stimulating nerves that connect directly to the brain.
