Autonomic Nervous System Drugs Flashcards
____ sends impulses to the CNS
Afferent/ Sensory
____ receives impulses, transmits through the spinal cord to effector organ cells
Efferent/ Motor
Autonomic Nervous System/ Visceral System
it is involuntary and controls and regulates the heart, GI, respiratory system, bladder, eyes, and glands
Somatic Nervous System
it is voluntary and it innervates the skeletal muscles
Terminal Neurotransmitter of Sympathetic Nervous System
Norepinephrine
Receptor organ cells of the Sympathetic Nervous System
- Alpha (Alpha 1, Alpha 2)
- Beta (Beta 1, Beta 2)
Terminal Neurotransmitter of Parasympathetic Nervous System
Acetylcholine
Receptor organ cells of Parasympathetic Nervous System
- Nicotinic
- Muscarinic
____ inactivates acetylcholine before reaching organs cells
Acetylcholinesterase
Sympathetic Nervous System’s Common Responses
- dilates pupils
- dilates bronchioles
- increases heart rate
- constricts blood vessels
- relaxes smooth muscles of the GI
- relaxes uterine muscles
Parasympathetic Nervous System’s Common Responses
- constricts pupils
- constricts bronchioles, increases secretions
- decreases heart rate
- dilates blood vessels
- increases peristalsis
- increases salivation
Receptor Theory
drugs act through receptors by binding to the receptors to initiate a response or prevent a response and it is similar to the fit of the right key in a lock
____stimulates adrenergic receptors
Sympathomimetics/ Adrenergic Agonists
Category Based on Chemical Structure
- Catecholamines
- it has a catechol ring and amines - Noncatecholamines
- it has no catechol ring
Therapeutic and Pharmacologic Class of Epinephrine
Therapeutic Class: Vasopressor
Pharmacologic Class: Adrenergic
