When receptors are activated, they generate a signal that triggers a cellular response. This signal is typically transmitted through a series of molecular pathways within the cell, leading to a specific physiological outcome such as gene expression, muscle contraction, or cell division.
dissolved odorants bind to the receptors in the cilium membranes.
As urine accumulates in the bladder, stretch receptors in the bladder wall are activated. These receptors send signals to the brain to indicate that the bladder is full and needs to be emptied. This activates the urge to urinate.
Actually, the postganglionic receptors for the parasympathetic nervous system (PNS) are predominantly muscarinic receptors. These receptors are activated by acetylcholine released from postganglionic parasympathetic nerve terminals.
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.
Heat receptors detect thermal stimuli, such as higher temperatures above the baseline level. When activated, these receptors send signals to the brain, resulting in the perception of warmth or heat.
The olfactory receptors are activated by specific odor molecules that bind to them. This binding process triggers a series of chemical reactions that generate electrical signals, which are then sent to the brain for processing and interpretation as a particular scent.
No.. The capsule has pain receptors which are activated when it is stretched
Pain receptors :)
Stretch receptors in the bladder wall are activated when the bladder fills with urine or liquid. These receptors signal the brain to indicate the fullness of the bladder, triggering the urge to urinate.

Venus Flytrap receptors are multimodal 7 transmembrane G-protein coupled receptors activated by extracellular calcium ions.
Cold receptors would be activated, maybe causing you to shiver.

When taste and smell receptors are activated by a stimulus, they send signals to the brain which are interpreted as specific tastes and smells. This process helps us identify and enjoy different flavors and scents in our environment.
