Autonomic Nervous System drugs Flashcards
What is Autonomic Nervous System?
Involuntary physiological activities including heart rate, blood pressure, breathing, digestion, and sexual arousal are regulated by the autonomic nervous system, a part of the peripheral nervous system.
What are the 2 key components in the ANS?
Sympathetic/Adrenergic and Parasympathetic/Cholinergic
What is Somatic Nervous System
The somatic nervous system, also known as the voluntary nervous system, is the area of the peripheral nervous system responsible for the voluntary regulation of skeletal muscle movement.
What are the 2 types of neurons?
Afferent and Efferent
What is the difference between Afferent and Efferent?
Afferent is directly send impulses to the central nervous system while the efferent is receiving impulses communicates to cells of effector organs through the spinal cord.
What is neurotransmitters?
Your body depends on neurotransmitters, which are chemical messengers. They are responsible for transporting chemical signals, or “messages,” from one neuron (nerve cell) to the subsequent target cell.
What is Synaptic Transmission?
The biological mechanism through which a neuron interacts with a target cell across a synapse is known as synaptic transmission.
What is Sympathetic Nervous System?
SNS impulses are reactions to a very precise set of stimuli necessitating activation of the “fight or flight” response. The Terminal Neurotransmitter is Norepinephrine also the Receptor organ cells are Alpha and Beta.
What is Parasympathetic Nervous System?
The PNS is made up of preganglionic and postganglionic nerves, just as the SNS. The Terminal Neurotransmitter is Nicotinic and Muscarinic.
What are the difference between Sympa and Parasympa?
SYMPA – PARASYMPA
Dilates Pupils – Constrict pupils
Dilates Brochioles – Constrict Bronchioles,Increase Secretions
Increase Heart Rate – Decrease Heart Rate
Constricts Blood Vessels – Dilates Blood Vessels
Relaxes smooth muscles of the GI – Increases peristalsis
What is the muscle contract when pupil response?
When pupil Constricts, the pupil response is bright light, and it is a Circular Muscle Contract. While when pupil Dilates, the pupil response is dim light, and it is a Radial Muscle Contract.
What is the Receptor Theory?
Drugs work by attaching to receptors to either start or stop a reaction, depending on the situation. It is comparable to how well a lock fits when the proper key is used.
What is Agonist?
Medications that cause a reaction.
What is Antagonist?
Medications that prevent reactions.
What is Pharmacologic Effect?
When autonomic medications are used, the intention is to address target organ dysfunction rather than an autonomic condition.
