What is receptor desensitisation?
Receptors generate a cellular response upon binding their specific ligand. This response can vary in magnitude. Desensitisation is a phenomenon in which activation of a receptor can reduce the magnitude of the response if it is subsequently activated again. Usually the longer a receptor is activated for the greater the desensitisation will be. There are 3 general mechanisms as to how desensitisation occurs. The first is uncoupling of the receptor from proteins which generate the cellular response. The second is internalising receptors so that they cannot be activated. The third is reducing production of receptors so less are available. In general mechanism 1 is short term, 2 is mid-term and 3 is long term.
Which sensory receptors are activated as you descend in an elevator?
MACULA
What is activated as urine accumulates in that bladder?
Stretch receptors
The receptors for smell are activated when?
dissolved odorants bind to the receptors in the cilium membranes.
When you touch something cold what receptors would be activated?
cold receptors, it will probably cause you to shiver . hope this helped :)
Does your liver have pain receptors?
No.. The capsule has pain receptors which are activated when it is stretched
What type of receptors will be activated when you get a paper cut on you finger?
Pain receptors :)

What are the Venus Flytrap receptors?
Venus Flytrap receptors are multimodal 7 transmembrane G-protein coupled receptors activated by extracellular calcium ions.
Muscarinic receptors are inhibitory and excitatory?
Depending on the effector organ it can be inhibitory or excitatory. The muscarinic receptors are activated from the parasympathetic nervous system. So the effect of muscarinic receptors activated on the heart, it will slow the heart down. However, on the gastrointestinal tract, it will increase motility.
