AUTONOMIC NERVOUS SYSTEM TCC PARAMEDIC

EPS

(Extrapyramidal Symptoms) common side effects of antipsychotic medications, including muscle tremors and parkinsonism-like efects

Norepinephrine

A hormone that is released by the adrenal medulla and by the sympathetic nerves and functions as a neurotransmitter. It is also used as a drug to raise blood pressure.

Sympathetic Nervous System

A part of the nervous system that serves to accelerate the heart rate, constrict blood vessels, and raise blood pressure.

Anticholinergic

Agents that oppose the parasympathetic (cholinergic) nervous system

Alpha 1 receptors

Also called alpha-adrenergic receptor it is a vasoconstriction, intestinal relaxation, pupil dilation.

acetylcholinesterase

An enzyme that catalyzes the breakdown of acetylcholine and of some other choline esters that function as neurotransmitters.

Parasympathetic Nervous System

Arises from the brainstem and the sacral segments of the spinal cord (Feed or Breed)

SLUDGE

Effects of cholinergic stimulation: salivation, lacrimation, urination, defecation, gastric mobility, emesis

Catecholamines

Epinephrine and norepinephrine, hormones that strongly affect the nervous and cardiovascular systems, metabolic rate, temperature, and smooth muscles.

Nicotinic N

Found in all autonomic ganglia, where acetylcholine serves as the presynaptic neurotransmitter of both the parasympathetic and sympathetic nervous system.

Nicotinic M

Found in the neuromuscular junction and initiate muscular contraction as part of the somatic nervous system.

Autonomic Ganglia

Groups of autonomic nerve cells located outside the central nervous system

Beta 1 receptors

Located in the heart it increase heart rate, conductivity, automaticity, and contractility

Sympathomimetic

Medications or other substance that causes effects like those of the sympathetic nervous system (adrenergic)

Parasymatholytic

Medications that blocks or inhibits the actions of the parasympathetic nervous system ( Anticholinergic )

Sympatholytic

Medications that blocks the actions of the sympathetic nervous system. (antiadrenergic)

Preganglionic Nerves

Nerve Fibers that extend from the central nervous system to the autonomic ganglia

Postganglionic Nerves

Nerve fibers that extend from the autonomic ganglia to the target tissues

Autonomic Nervous System Adrenergic

Part of the nervous system that controls involuntary actions

Muscarinic

Receptors found throughout the body in many organs, and is primarily responsible for promoting the parasympathetic response.

Dopaminergic

Releasing or involving dopamine as a neurotransmitter. Drugs with this effect are used in the treatment of Parkinson's disease and some psychiatric disorders

Cholinergic

Synapses that use acetylcholine as the neurotransmiter

Acetylcholine

a compound that occurs throughout the nervous system, in which it functions as a neurotransmitter.

Neurotransmiter

chemical messenger that conducts a nervous impulse across the synapse

Beta 2 receptors

located in the lungs (Bronchodilation), arterioles (Dilation), uterus (Inhibits contractions) , skeletal muscles(Tremors).

Parasympathomimetic

medications that causes effects like those of the parasympathetic nervous system ( Cholinergic )

Alpha 2 receptors

smooth muscle contraction and neurotransmitter inhibition
