what are receptor cells in psychology? n. 1. the cell in a sensory system that is responsible for stimulus transduction. Receptor cells are specialized to detect and respond to specific stimuli in the external or internal environment.

What are the receptor cells? Receptors. Receptors are groups of specialised cells. They detect a change in the environment (stimulus) and stimulate electrical impulses in response. Sense organs contain groups of receptors that respond to specific stimuli.
What are sense receptors psychology? Sensory Receptors are specialized neurons or nerve endings that respond to changes in the environment by converting energy from a specific stimulus into an action potential (a process known as transduction).
What is an example of receptor? There are many receptors. There is a receptor for (insulin; there is a receptor for low-density lipoproteins (LDL); etc. To take an example, the receptor for substance P, a molecule that acts as a messenger for the sensation of pain, is a unique harbor on the cell surface where substance P docks.

what do you call something that binds to a receptor?
Activated receptors directly or indirectly regulate cellular biochemical processes (eg, ion conductance, protein phosphorylation, DNA transcription, enzymatic activity). Molecules (eg, drugs, hormones, neurotransmitters) that bind to a receptor are called ligands.
what receptors does tropicamide bind to?
Tropicamide is a non-selective muscarinic antagonist that binds to all subtypes of muscarinic receptors. By binding to muscarinic receptors, tropicamide relaxes the pupillary sphincter muscle and causes pupil dilation. By blocking the muscarinic receptors of the ciliary body, tropicamide also prevents accommodation.
