Adaption
Because that is the upper side of your tongue (the dorsal side), and all food and liquids pass over this surface, giving the taste receptors stimulation to your brain to register whatever tastes are present.
Because response of a cell to a signaling requires that the responding cell have receptors that recognize that hormone. Only target cells of a signal have the receptors for the signal.
Touch - Mechanical receptors Light- Photo receptors Heat- Thermo receptors
The sensory receptors for your nose is the semicircular canals and the cochlea
Sensory adaptation
Thermo receptors can adapt to stimuli. The temperature change at first strongly stimulated the thermo receptors. With continued exposure, the warmth receptors quickly stop responding but not completely. Sensation is not as noticeable.
iodine.
lemons
Light receptors known as rods and cones
constriction of the blood vessels
Adaption
Sensory Adaptation, which is an adjustment made by the sensory receptors upon continuous stimulation.
Nerve receptors are stimulated during urination. This stimulation occurs when the walls of the bladder contract and the urination reflex is automatically activated.
beta 1 receptors
You have receptors for three primary colours in your retina. You can perceive the thousands of colours due to stimulation of the these receptors at different intensity in various permutations and combinations.
muscarinic (M3,M4)
