Sudden inexplicable episodes of intense fear with an impending sense of doom where it is difficult to breathe and a person feels like their heart is racing are associated with <u>panic disorder</u>.
Human beings with panic disorder have common and surprising panic attacks. Panic attacks are unexpected periods of severe fear, soreness, or feeling of dropping manage even if there is no clean hazard or trigger.
As with many intellectual health situations, the exact motive of panic disorder is not completely understood. But it's a concept related to a mixture of things, which include: a traumatic or very stressful lifestyle experience, together with bereavement. having a close member of the family with panic disorder.
Panic disorder is whilst you've had at the least panic attacks (you feel terrified and beaten, even though you're not in any hazard) and constant fear and alternate your routine to keep from having some other one. it is a kind of anxiety sickness.

"Socialism with a face" introduced by Alexander Dubcek gave the people of Czechoslovakia a sense of new freedom.
He eased up on the country's strict policy in regards to connection with other countries, freedom of speech, and the control of the media.
This create a country that operate on free expression which never seen before by socialist government under communistic parties

Answer:
Explanation:
Action potential
It is the potential or power or electrical energy required to generate impulses and provides communication between the neurons is called action potential. Normally cell membrane consists of potential is called resting membrane potential() -70mV. The action potential is due to exchange of different ions across the membrane.
Phases of the action potential in a neuron are
i. Depolarization- it is caused by the influx of sodium and calcium ions through the opening of voltage-gated sodium and calcium channels. sodium ion influx is rapid than the calcium ions membrane potential -70mV to +30mV.
ii. Repolarization - It causes the efflux of potassium ions into the cell through the opening of potassium channels. the membrane returning to resting membrane potential.
iii. After- Hyper polarization - in this stage the potassium channels remain open and causes re polarization and comes to normal membrane potential.
The generation of impulses(depolarization) in neuron mainly depends on influx sodium and calcium ions without these ions, no action potential developed and neuron firing does not occur.
If the drugs inhibit these channels, no depolarization, no action potential, no neuronal firing or communication.
The channels involved in an action potential are voltage-gated sodium channels, potassium channels, and calcium channels.
The action potential is required for transmission of information one are to another area in the body.
The responses to different stimuli is due to action potential.
