Study Notes
Adrenergic Receptors
- Sympathomimetic drugs directly activate adrenergic receptors.
Location of Adrenergic Receptors
- Adrenergic receptors are primarily located in the heart, smooth muscle, and glands.
Receptors in Vasculature
- Beta-2 receptors are present in the vasculature of skeletal muscles.
Adrenergic Neurotransmitter
- Norepinephrine is the neurotransmitter primarily used by adrenergic neurons.
Sympatholytics
- Sympatholytics block the action of adrenergic neurons, reducing sympathetic activity.
