Adrenergic Receptors. Receptors are located on smooth muscle cardiac pacemaker myocardium and glands. Related questions 0 votes.
Adrenergic receptors respond to sympathetic stimulation and blood-borne epinephrine. Vascular smooth muscle has two types of alpha-adrenoceptors. It can be released from adrenergic autonomic nerve terminals.
Adrenergic receptors are located on cells of tissues and organs throughout the body and are the targets of catecholamines such as epinephrine and norepinephrine.
However clinical significance of this phenomenon is unclear. Adrenergic drugs also interact with these receptors. The receptors consist of seven membrane-spanning domains three intra- and three extracellular loops one extracellular N-terminal domain and one intracellular C-terminal tail. Binding to β receptors on the post-synaptic membrane is coupled to a G s.
