How sensory receptors categorize
According to stimuli they gather how are the sensory receptors categorized?
Expert
The sensory receptors are categorized according to stimuli they get: mechanoreceptors are stimulated by pressure (e.g., sound or touch); chemoreceptors respond to chemical stimuli (taste, olfactory, pH, metabolite concentration, and so forth.); thermoreceptors are sensitive to temperature alters; photoreceptors are stimulated by the light; nocireceptors send pain information; proprioceptors are sensitive to spatial position of muscles and joints (they create information for equilibrium of body) sent the signal to particular receptors in membrane of the neuron that is receiving stimulus. The binding of neurotransmitters to those receptors is a reversible phenomenon which changes the membrane permeability of region since the binding cause’s sodium channels to open. When positive sodium ions enter cell in favor of their concentration gradient the membrane voltage raises, thus lessening negative polarization. If this depolarization reaches excitation threshold (about –50 mV) the depolarization continues, the action potential is reached and impulse is transmitted along cell membrane.
