False. While beta-adrenergic receptors are commonly found in the heart, there are also other types of receptors present, such as alpha-adrenergic receptors and muscarinic receptors, that play a role in regulating heart function.
Gustatory receptors are also present in the mouths of animals. These are novel proteins which are able to recognize a variety of chemicals.
There are no known receptors that are found everywhere throughout the body, but not in the skin. Receptors present in the skin include various sensory receptors such as mechanoreceptors, thermoreceptors, nociceptors, and others that are responsible for detecting touch, temperature, and pain.
Tonic receptors are sensory receptors that provide a continuous signal to the brain as long as the stimulus is present. They help maintain our awareness of information such as body position, muscle tension, and joint sense. Examples include the those responsible for posture and balance.
Organs innervated by the parasympathetic nervous system. One addition to that are sweat glands. They are innervated by sympathetic nervous system, however, they have muscarinic receptors, NOT adrenergic receptors.
Beta1 and beta2 are different types of adrenergic receptors found in the body. Beta1 receptors are primarily located in the heart and play a role in regulating heart rate and contractility. Beta2 receptors are found in the lungs, blood vessels, and other tissues, and are involved in processes such as smooth muscle relaxation and bronchodilation.
The beta2 adrenergic receptor is primarily responsible for bronchodilation when stimulated by agonists such as beta2-adrenergic agonists like albuterol. Stimulation of these receptors leads to smooth muscle relaxation in the airways, resulting in increased airflow and improved breathing.
Beta 2 receptors are responsible for keeping your bronchi open so you can breath. If they are antagonized, your bronchi will close up. In asthma you want to use Beta2 AGONISTS, drugs that stimulate these receptors, so you can breath.

These Receptors are present in Carotid and Aortic Arteries of Tetrapods and they have a vital role in regulation of Blood Pressure.
Beta2-microglobulin is a protein found on the surface of many cells. Testing is done primarily when evaluating a person for certain kinds of cancer affecting white blood cells.
False. While beta-adrenergic receptors are commonly found in the heart, there are also other types of receptors present, such as alpha-adrenergic receptors and muscarinic receptors, that play a role in regulating heart function.
The number of dendritic endings present
Adrenaline targets various organs,mainly - the Heart, Blood vessels, Smooth muscles(of bronchi, uterus, gastrointestinal tract,bladder etc.), the eye (radial muscles of iris), skeletal muscles (central nervous system also, but weak effect is seen there), metabolic actions (via liver)It acts via various alpha and beta receptors present at these target organs.Its main actions can be simplified as below:Heart-via beta 1 receptors-Adrenaline increases the Heart rate, force of contraction, cardiac output and conduction velocityBlood vessels-via alpha and beta2 receptors causes constriction mainly in vessels of skin, kidneys and dilatation in vessels of skeletal muscles, liver.Bronchial smooth muscles - via beta2 receptors- causes broncho dilatation.Blood pressure- overall rise in blood pressureEye- via alpha1 receptors- contraction of radial muscles if iris,therefore increases size of pupil (mydriasis)CNS- restlessness, apprehension, tremorsMetabolic action- rise in blood glucose levels, lactic acid level, free fatty acid levels.
Gustatory receptors are also present in the mouths of animals. These are novel proteins which are able to recognize a variety of chemicals.
