The two main types of photoreceptors in the retina are rods and cones. Rods are highly sensitive to light and enable vision in low-light conditions, but they do not detect color. Cones, on the other hand, function in brighter light and are responsible for color vision and detail. Together, they allow the human eye to perceive a wide range of light intensities and colors.

What are two types of receptors involved in the cough reflex?
Two types of receptors involved in the cough reflex include irritant receptors, which are sensitive to noxious stimuli in the airways, and stretch receptors, which respond to mechanical distortion of the airways. Activation of these receptors triggers the cough reflex to protect the respiratory tract.
How many different kinds of receptors are there for acetylcholine?
There are two main types of receptors for acetylcholine: muscarinic receptors, which are G-protein coupled receptors, and nicotinic receptors, which are ligand-gated ion channels. Each type of receptor is further classified into different subtypes based on their structure and function.
What are the two types of receptors in the skin that detect fine touch?
There are not tow types of sensory receptors in the skin there are many types of sensory receptors in the skin i.e., in the CUTANEOUS RECEPTORS of the MECHANORECEPTORS. They are the: Meissner's corpuscles, Merkel's disc, Paccinian corpuscles, Ruffini's end organs, Free Nerve Endings and Hari Follicel Organs.
Which of the five senses contain photoreceptors?
The eyes contain photo-receptors.
What are the types of alpha receptors?
There are two main types of alpha receptors: alpha-1 and alpha-2. Alpha-1 receptors are located in smooth muscle cells of blood vessels, causing vasoconstriction when activated. Alpha-2 receptors are located both presynaptically and postsynaptically in the central and peripheral nervous systems, regulating the release of neurotransmitters.
What are The two types of receptors that bind acetylcholine?
The two types of receptors that bind acetylcholine are nicotinic receptors and muscarinic receptors. Nicotinic receptors are ionotropic receptors found at the neuromuscular junction and in the autonomic ganglia, while muscarinic receptors are G-protein coupled receptors found in various organs like the heart, lungs, and digestive system.

Temperature senses use two types of?
The two types of temperature senses are warm receptors and cold receptors. Warm receptors detect increases in temperature, while cold receptors detect decreases in temperature. Together, they help our bodies maintain a stable internal temperature.
The two types of receptors that bind acetylcholine are?
nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotinemuscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.Nicotinic and muscarinic are two main kinds of "cholinergic" receptors.

What are light receptors?
Light receptors are found in the eye. There are two types of receptors; rods and cones. Rods produce the black and white pigments and the Cones produce the color pigments.
Which of the five senses contain photoreceptors?
The eyes contain photo-receptors.

Alpha-2 receptors are located both presynaptically and postsynaptically in the central and peripheral nervous systems, regulating the release of neurotransmitters.
What are two classifications of sensory receptors?
There are many different sensory receptors, but olfactory receptors in the nose, and cones and rods in the eyes are two specific types of sensory receptors. Olfactory detects the chemical presence and your brain identifies it as a smell. The rods and cones of the eye process light and color to form images that your brain processes as vision.
What are three types of receptors?
There are four different types of receptors in the skin. There are merkel receptors, meissner corpuscles, ruffini cylinders and pacinian corpuscles.
