Sensory Adaptation, which is an adjustment made by the sensory receptors upon continuous stimulation.
Extream cold and extream heat feel almost the same because te pain receptors are being stimulated.
the gland in men stimulated by TSH hormone only while in women there is additional estrogen receptors on gland so gland stimulated by TSH and estrogen
The cell membrane becomes more permeable to the sodium potassium ions.
When a ligand-gated channel is stimulated, there is movement toward the extracellular side of the cell membrane. This allows the channel to become permeable to different ions.
When beta receptors are stimulated, it decreases the heart rate to treat for low blood pressure.
Cutaneous sensory receptors in the skin are part of the somatosensory portion of the nervous system.
Mechanoreceptors
Thermoreceptors
Irritant receptors:-Irritant receptors lie between airway epithelial cells. They are stimulated by mechanical stimuli, inhaled dusts, cold air, noxious gases and cigarette smoke. The receptors show rapid adaptation when they are continuously stimulated. Impulses travel via myelinated fibers in the vagus nerve. Irritant receptors lie betwIrritant receptors in more peripheral bronchi are insensitive to mechanical irritants, but they are sensitive to chemical stimuli; the pattern is reversed in the central airways. Reflex effects include bronchoconstriction and hyperpnoea.Irritant receptors are also sensitive to histamine and can thus contribute to the bronchoconstrictor response in asthmatic subjects in whom histamine is released from mast cells or other cells.een airway epithelial cells.

Nerve receptors are stimulated during urination. This stimulation occurs when the walls of the bladder contract and the urination reflex is automatically activated.

Sensory receptors.
sodium ions enter the postsynaptic neuron.
Pain receptors are bare dendrites that react to a certain type of stimulus. Some pain receptors become activated when extremes of heat or cold cause your skin temperature to rise or fall to dangerous levels. Hope this helps!
