Type I cutaneous mechanoreceptor (Merkel disc), Type II cutaneous mechanoreceptor (Ruffini corpuscle), thermoreceptor, muscle spindles are the receptors fires continuously as long as a stimulation is applied. Thus, option b, f, g, h are correct.
<h3>
what are the role of receptors?</h3>
Receptors are the sensing protein molecule which bind to specific molecule in cell called as ligand.
The ligand can be a drug or any endogenous molecule like neurotransmitters, hormones, etc.
Based on molecular structure and mode of action four major types of receptors are found such as G-protein coupled receptors, ligand-gated ion channel receptors, Nuclear receptors, Kinase-linked receptors
Almost all the receptors have endogenous ligands such serotonin, acetylcholine etc.
Hence, option b, f, g, h are correct.
