The smell of a substance is related to its molecular shape through the interaction of odorant molecules with olfactory receptors in the nose. The specific shape and structure of the odorant molecules determine how they fit into the receptors, leading to the perception of different smells. Small changes in molecular shape can result in significant differences in odor perception.
There are two main types of receptors for acetylcholine: muscarinic receptors, which are G-protein coupled receptors, and nicotinic receptors, which are ligand-gated ion channels. Each type of receptor is further classified into different subtypes based on their structure and function.
You would find receptors that respond to various stimuli in different parts of the body, such as the skin for touch and temperature receptors, the nose for olfactory receptors, and the tongue for taste receptors. Additionally, there are receptors located in organs and tissues that respond to internal conditions like pressure, pH, and hormones.
Yes, the skin on different parts of the body has varying densities of nerve receptors. Areas with a higher concentration of nerve receptors, like the fingertips and lips, are more sensitive to touch, temperature, and pain. Other areas, such as the back, have fewer nerve receptors and are less sensitive.
Yes, beta receptors are adrenergic receptors, meaning they bind to adrenaline (epinephrine) and norepinephrine. There are three subtypes of beta receptors: Beta-1, Beta-2, and Beta-3, each with different functions and tissue distributions.

Simple covalent molecules have a smell because they can bind to receptors in our nose, triggering a signal to the brain that we interpret as a smell. Different molecules bind to different receptors, leading to a variety of smells. The specific shape and chemical properties of the molecule determine which receptors it can bind to, creating the perception of smell.
You have several sensory receptors and they all measure differences in pressure, displacement, and movement. The main ones are the Merkle, Meissner, Pacinian, Raffini, Krause, Hair follicle receptors, and the pain receptors.
Odor molecules in the air reach the olfactory receptors in the nose. These receptors then send signals to the brain, specifically the olfactory bulb, where the brain processes these signals and identifies the odor. Each odor molecule has a specific shape that fits into certain receptors, leading to the perception of different smells.

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
There are four different types of receptors in the skin. There are merkel receptors, meissner corpuscles, ruffini cylinders and pacinian corpuscles.
Adaptation of sensory receptors refers to the way in which our senses changed under different circumstances and stimuli.
You would find receptors that respond to various stimuli in different parts of the body, such as the skin for touch and temperature receptors, the nose for olfactory receptors, and the tongue for taste receptors. Additionally, there are receptors located in organs and tissues that respond to internal conditions like pressure, pH, and hormones.
You have receptors for three primary colours in your retina. You can perceive the thousands of colours due to stimulation of the these receptors at different intensity in various permutations and combinations.
Taste - gustatory receptors (taste buds) Vision - optical receptors (retina and optic nerve) Hearing - phono receptors (cochlea - inner ear) Smell - olfactory receptors (nose) Touch - tactile receptors (skin, tongue) (Also : Heat - thermo receptors.)
The eye's visual receptors reside within the retina. The eye's visual receptors consist of four different types of receptors including rods, blue cones, red cones and green cones.
