Question: What are the receptors of the autonomic nervous system?

What are the neurotransmitters of the autonomic nervous system?

The neurotransmitters involved in the ANS are acetylcholine, norepinephrine, and epinephrine.

What are alpha and beta receptors?

Alpha receptors are mostly involved in the stimulation of effector cells and constriction of blood vessels. On the other hand, beta receptors are mostly involved in the relaxation of effector cells and dilatation of blood vessels.

What are the two types of autonomic nervous system?

The autonomic nervous system has two main divisions:

  • Sympathetic.
  • Parasympathetic.

What do beta-2 receptors do?

Beta-2 adrenergic receptors are cell-surface receptors clinically taken advantage of in the management of bronchospasm as in patients with bronchial asthma and chronic obstructive pulmonary disease. Medications targeting these receptors are either agonistic or antagonistic.

What is the function of alpha receptors?

Alpha 1 receptors are the classic postsynaptic alpha receptors and are found on vascular smooth muscle. They determine both arteriolar resistance and venous capacitance, and thus BP. Alpha 2 receptors are found both in the brain and in the periphery. In the brain stem, they modulate sympathetic outflow.

What is the function of adrenergic receptors?

Adrenergic receptors are cell surface glycoproteins that recognize and selectively bind the catecholamines, norepinephrine and epinephrine, which are released from sympathetic nerve endings and the adrenal medulla.

Is dopamine cholinergic or adrenergic?

Dopamine is both an adrenergic and dopamine agonist. Dopamine is a neurotransmitter and an immediate precursor to norepinephrine.
