Adrenergic Innervation (Maintenance)

Adrenergic innervation (maintenance) refers to the ongoing role of adrenergic signaling in sustaining physiological states such as wakefulness/arousal and homeostasis within various organ systems. It involves the release of norepinephrine and epinephrine from sympathetic nerves, which act on adrenergic receptors (α₁, α₂, β₁, β₂, β₃) to regulate cardiovascular function, metabolic processes, and circadian rhythms. Disruption of adrenergic signaling can lead to various pathologies, including hypertension, cardiac arrhythmias, and sleep disorders.

Other names

Sympathetic Nervous System (Maintenance)Catecholaminergic Neurotransmission (Maintenance)

Neurotransmitter release from sympathetic nerve terminals and binding to adrenergic receptors (α₁, α₂, β₁, β₂, β₃) on target tissues, leading to activation of intracellular signaling cascades.
