Autonomic Nervous System Pharmacology

This division of the Nervous System is composed of the brain and spinal cord.

• Autonomic Nervous System (ANS)

• Central Nervous System (CNS)

• Peripheral Nervous System (PNS)

• Somatic Nervous System (SNS)

Composed of motor nerve cells that transmit impulses to smooth muscles (intestinal, urinary bladder, uterus, eyes, lungs, and small arteries and veins), cardiac muscle, and glands

• Central Nervous System (CNS)

• Somatic Nervous System (SNS)

• Peripheral Nervous System (PNS)

• Autonomic Nervous System (ANS)

The Autonomic Nervous System is divided into two divisions, Parasympathetic and Sympathetic.

• True

• False

The short postganglionic neurons synapse at or near the target organs are part of the Parasympathetic Division of the ANS

• True

• False

The following are all Primary Neurotransmitters and found in the ANS EXCEPT?

• Acetylcholine

• Neuroepinephrine

• Epinephrine

Alpha 1 and Alpha 2 receptors are located on postganglionic smooth muscle.

• True

• False

Answer explanation

Alpha 2 receptors are postganglionic neurons not on the smooth muscle

Beta receptors in the heart are referred to as?

• Beta 2

• Beta 3

• Beta 1

The actions of Sympathomimetic Drugs causes all the following EXCEPT?

• Action is antagonized by blocking agents

• Regulate neurotransmitter release

• Action is antagonized by an adrenergic blocking agent

• Excitatory action (e.g., contraction of smooth muscle) is due to stimulation receptors

Answer explanation

Dopamine regulates neurotransmitter release
