The value of receptors in the body having thresholds is that without them we would constantly be overstimulated. If we didn't have thresholds, everything, sound, taste, touch and noise would be unbearable, as we would have to respond to everything. Thresholds allow us to ignore unimportant stimuli, and to not become overwhelmed by reacting to every stimulus around us.
Hormone and receptor interactions are based on specific binding between the hormone and its receptor. The receptor acts as a target for the hormone, triggering a series of cellular responses once bound. This interaction is highly specific, allowing for precise signaling within the body.
The shape of hormone receptors is crucial because it determines the binding specificity between the hormone and the receptor. When a hormone attaches to its specific receptor, it triggers a signaling cascade that regulates various physiological processes in the body. The specific shape ensures that only the correct hormone can bind to the receptor, leading to a specific biological response.
A sub-threshold change in membrane potential in the cell body, such as an excitatory post-synaptic potential (EPSP), does not reach the threshold for action potential initiation. As it travels along the dendrites and cell body, it decays and dissipates, failing to trigger an action potential. This phenomenon is crucial in the integration of signals by neurons.
Mucous membranes contain various types of receptor cells, including pain receptors (nociceptors), temperature receptors (thermoreceptors), and chemical receptors (chemoreceptors). These receptor cells help the body sense and respond to different stimuli in the environment.
Yes, target cells possess specific receptor molecules on their surface that bind to signaling molecules such as hormones or neurotransmitters. This interaction triggers a cellular response or change in function within the target cell, influencing various physiological processes within the body.
why people have a different taste threshold from someone else or even have different density of receptors whithin our body? The receptor density is different. I think it's due to genetics bumping into environmental history. For example, I'd bet that flame swallowers have a reduced receptor density. Some people can taste X while others can't, and often the difference is due to genetics.
Density of receptor cells are the amount of receptor cells in a specific area of the body. This could be in the lips.

The main role of the NMDA receptor in the body is in ensuring neural plasticity. Further research is on-going to further refine understanding of this receptor, and this conclusion may change in future as more studies may find further roles for this receptor.
An agonist drug binds to and activates a receptor in the body, producing a response similar to that of the endogenous ligand. This leads to an increase in the activity of the receptor, resulting in a physiological response.
it means your body sends more pain then needed towards places that have been punched, kicked ect then someone with regular pain threshold. as pain is just a message from your body saying to stop but if you have a low pain threshold your body sends too much pain.

Sensory Receptor
The calcium-sensing receptor (CaSR) is a receptor specifically activated by calcium ions. It plays a crucial role in maintaining calcium homeostasis in the body by regulating the levels of calcium in the blood.
