Beta-adrenoceptor (Noun)
Meaning
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).
Classification
Nouns denoting body parts.
Examples
- The beta-adrenoceptor is a specific type of receptor that plays a crucial role in the regulation of the sympathetic nervous system.
- Stimulation of the beta-adrenoceptor by certain agonists can lead to increased heart rate and vasodilation.
- The beta-adrenoceptor is thought to be responsible for the therapeutic effects of certain medications used to treat conditions such as asthma and hypertension.
- Research has shown that the beta-adrenoceptor is a key target for the action of catecholamines, such as adrenaline and noradrenaline.
- The beta-adrenoceptor has been subdivided into three subtypes, beta-1, beta-2, and beta-3, each with distinct functions and tissue distributions.
