Meaning of beta-adrenoceptor
beta-adrenoceptor (n)
receptors postulated to exist on nerve cell membranes of the sympathetic nervous system in order to explain the specificity of certain agents that affect only some sympathetic activities (such as vasodilation and increased heart beat)
beta-adrenoceptor Sentence Examples
- Beta-adrenoceptors are receptors that bind adrenaline and noradrenaline, hormones that mediate the sympathetic nervous system's "fight or flight" response.
- Beta-adrenoceptors have two main subtypes, beta-1 and beta-2, which differ in their location, function, and affinity for different agonists and antagonists.
- Beta-1 adrenoceptors are primarily found in the heart, where they mediate the effects of catecholamines on heart rate and contractility.
- Beta-2 adrenoceptors are more widely distributed, found in smooth muscle, vascular tissue, and the lungs, where they regulate bronchodilation and vasodilation.
- Beta-blockers, such as propranolol and metoprolol, are drugs that competitively bind to beta-adrenoceptors and block their activation, which is used to treat conditions like hypertension and arrhythmias.
- Beta-agonists, such as salmeterol and albuterol, are drugs that activate beta-adrenoceptors, which is used to treat conditions like asthma and chronic obstructive pulmonary disease (COPD).
- The stimulation of beta-adrenoceptors by catecholamines increases heart rate, blood pressure, and cardiac output, preparing the body for physical activity or stress.
- Beta-adrenoceptors are also involved in regulating airway resistance, glycogenolysis, lipolysis, and other metabolic processes.
- Dysregulation of beta-adrenoceptors can contribute to various cardiovascular and respiratory disorders, including hypertension, heart failure, and asthma.
- Research into beta-adrenoceptors has led to the development of novel therapeutic strategies for treating a wide range of conditions.
