Gustatory receptors are part of the sense of taste. They are in your mouth. Olfactory receptors are part of the sense of smell. They are in your nose.
The olfactory system in humans is responsible for the sense of smell. It involves receptors in the nose that detect different odors in the environment and send signals to the brain for interpretation. Humans can distinguish between thousands of different smells due to the complex interactions of these olfactory receptors.
The human nose detects smells through specialized cells in the olfactory epithelium that contain odor receptors. When you breathe in, odor molecules bind to these receptors, sending signals to the brain's olfactory bulb, where they are interpreted as different smells. This allows us to perceive and differentiate between various scents in our environment.
Hyperosmia is an increased olfactory acuity (heightened sense of smell), usually caused by a lower threshold for odor.[1] This perceptual disorder arises when there is an abnormally increased signal at any point between the olfactory receptors and the olfactory cortex. The causes of hyperosmia may be genetic or environmental.
Much of what most people consider "taste" actually is smell. Most fruit really tastes pretty similar... if you plug up your nose so you can't smell it, the difference between two fruits of similar acidity and sweetness is mainly in the texture. So, in that sense, yes. There is no direct causal relationship on a physical level because taste and smell are mediated by different types of receptors detecting different types of chemical compounds. Smell is carried from olfactory receptors in the nose to the brain via the Olfactory Nerve (cranial nerve I). Taste is carried from gustatory receptors on the tongue to the brain via the Facial Nerve and the Glossopharyngeal Nerve (cranial nerves VII and IX). However, these signals are integrated extensively in the cerebrum and many connections are made. Therefore, it is plausible that the mere smell of a certain type of food can elicit the memory of the taste of that particular food.

The cues that are used to distinguish between smells include their molecular structure, volatility, intensity, and interactions with olfactory receptors in the nose. Each smell activates a specific set of receptors, which send signals to the brain for interpretation. The brain then processes these signals to differentiate between the two distinct smells.
The sense of smell is made possible by olfactory receptors in the nose that detect odor molecules in the air. When these receptors are activated, they send signals to the brain, which then processes and identifies the specific smell. This complex process allows us to perceive and differentiate between various scents in our environment.
Cellular receptors exist only on the outer surface of the plasma membrane
As you age, your sense of smell can become weaker, making it harder to detect and distinguish between different odors. This decrease in sensitivity is due to changes in the olfactory system and a reduction in the number of olfactory receptors in the nose. Older adults may also experience a decline in their ability to identify and remember smells accurately.
It doesn't atropine only acts on muscarinic receptors (it's a competitive antagonist here for ACh), but histamine acts on different receptors (histamine receptors). There is no direct interaction between atropine and histamine receptors
They both have ligands.
