BIOLOGICAL - Stress Managment Flashcards
What effect does a neurotransmitter which makes positive ions rush into dendrites have?
Excitatory effect
How do benzodiazapines (BZs) work?
They act by making the activity of GABA easier. This is done by enhances the effectiveness of GABA.
Give 2 examples of BZs
Valium
Librium
What is GABA?
An important chemical transmitter in the brain
In which part of the nervous system do BZs operate?
Central Nervous System
Brain
Which receptor sites do BZs bind to?
GABA receptors
What effect do BZs binding to GABA receptors have on ion channels?
Opens chanels allowing negitivly charged chloride ions to pass to the inside of the neuron.
How does having negitivly charged ions inside of the neuron help with stress?
Enhances the amound of inhibitry neuro transmitters released.
This reduces the brain activity & stress impulses therefore calming the person.
Give an example of an excitatory neurotransmitter
Serotonin
Give 2 side effects caused by using BZs
Drowsiness
Being less alert
Give an example of a beta blocker
Inderal
In which part of the nervous system do beta blockers operate?
The pathways of the sympathetic nervous system which is part of the autonomic branch of the peripheral nervous system
Which neuro transmitters/hormones are beta adrenic receptors responsive to?
Adrenaline
Noradrenaline
What do beta blockers do?
Reduce the activity of adrenaline & noradrenaline. The result of this being adrenergic receptors are blocked which are on the wall of the heart.
What effect does the blockage of adrenergic receptors have?
Slows the heart beat, lessenign the force that heart and blood vessels contract with.
