AUTONOMIC NERVOUS SYSTEM DRUG Flashcards
A component of the peripheral NS that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal
autonomic nervous system
Sympathetic, parasympathetic, and enteric
the three anatomically distinct divisions there in the ANS
The _____ nervous system tells the body to get ready for physical and mental activity.
Sympathetic
Alpha 1
Alpha 2
Beta 1
Beta 2
is called?
Four receptor organ cells
the terminal neurotransmitter of the parasympathetic nervous system
Acetylcholine
A Drugs that produce a response
Agonist drug
Has a catecholamine and amines
CATECHOLAMINES
It can
Dilates pupil
Dilates bronchioles
Increase heart rate
Constrict blood vessels
Relaxes smooth muscles of the GI
Relaxes uterine muscles
Sympathetic nervous system
side effects of adrenergic agonists drug
Tachycardia, palpitations, tremors, dizziness, increased blood pressure
Urinary retention r/t high doses
Nausea and vomiting offer food.
NON-DEPOLARIZING AGENT
DEPOLARIZING AGENT
the 2 agent of neuromuscular blockers (NM BLOCKERS)
- synthesis of the transmitter
- storage of neurotransmitter
- release of neurotransmitter
- action at the receptor
- termination
steps for synaptic transmission
It has the capability to
Constrict pupils.
Contracts bronchioles, and increase secretion.
Decrease heart rate
Dilates blood pressure
Increases peristalsis
Increases salvation
Parasympathetic nervous system
*sensory
* motor
* receptors
*interneurons
four types of neurons
It’s a neuron that receives impulses and transmits them through the spinal cord to the effector organ cell.
efferent neurons
is the terminal neurotransmitter of the sympathetic nervous system
Norepinephrine
Describe the outflow of the ANS
Projects widely to most target tissues and is not as highly focused as the somatic motor system
A drugs that block a response
Antagonist drug
Except in the brain and spinal cord, all the remaining nerves in other parts of the body are part of the
PNS ( Peripheral nervous system )
Sympathetic innervation effects
Increases heart rate and force of contraction
Parasympathetic innervation effects
it Decreases heart rate
