Central Nervous System

Question 1

What is Axonal conduction?

Answer 1

Conducting an action potential down the axon of the neuron.

Question 2

It is the process by which one neuron communicates with another. Information is passed down the axon of the neuron as an electrical impulse known as action potential

Answer 2

Synaptic transmission

Question 3

What does the Blood brain barrier do?

Answer 3

It shields the brain from toxic substances in the blood, supplies brain tissues with nutrients, and filters harmful compounds from the brain back to the bloodstream.

Question 4

Characteristics of ADHD (Attention Deficit/Hyperactive Disorder)

Answer 4

Question 5

A disorder that you’re unable to move or collapse

Answer 5

Narcolepsy

Question 6

What is the use of Amphetamines?

Answer 6

Stimulate the release of norepinephrine and dopamine from the brain and sympathetic nervous system.

Question 7

It is a brain disorder that causes unintended or uncontrollable movements, such as shaking, stiffness, and difficulty with balance and coordination.

Answer 7

Parkinson’s Disease

Question 8

What is Epilepsy?

Answer 8

It is a group of disorders characterized by excessive excitability of neurons in the cranial nervous system.

Question 9

What is Partial Seizure?

Answer 9

Happens when unusual electrical activity affects a small area of the brain.

Question 10

What is Generalized seizure?

Answer 10

Occurs when the abnormal electrical activity causing a seizure begins in both halves (hemispheres) of the brain at the same time.

Question 11

What are the Anti – Epileptic Drugs Mechanism?

Answer 11

Suppression of sodium, Suppression of Calcium Influx, Antagonism of Glutamate, Potentiation of GABA (Gamma – Aminobutyric Acid)

Question 12

What are the medicine for Partial Focal Seizures?

Answer 12

Carbamazepine, Gabapentin, Lamotrigine, Tiagabine, Topiramate

Question 13

It is a medicine that bind to a carrier protein and act at a receptor resulting in increased GABA in the brain.

Answer 13

Gabapentin

Question 14

What are the Uses of Non-Depolarizing Agents?

Answer 14

Ease of passage of an endotracheal tube
Decrease the amount of anesthetic required during surgery
Facilitate realigning bones and dislocated joints, Prevent muscle injury during electroconvulsive therapy

Question 15

What is Opioid Addiction?

Answer 15

Characteristic withdrawal syndrome occurs within 1 hour to several days after cessation of substance use.

Question 16

It Stabilize nerve cells to keep them from getting overexcited by increasing efflux or decreasing influx of sodium ions.

Answer 16

Phenytoin

Question 17

What is the effect of Phenobarbital?

Answer 17

Suppresses seizures by potentiating the effect of GABA, effective for partial and generalized seizures.

Question 18

it is known as Cornerstone of epilepsy therapy. It suppresses neuronal discharge by delaying recovery of sodium channels.

Answer 18

Carbamazepine

Question 19

It is used for treatment of malignant hyperthermia.

Answer 19

Dantrolene Sodium

Question 20

What is Abstinence Syndrome?

Answer 20

Withdrawing from a substance that has the potential to cause addiction. It may be distressing and may lead to coma and death.
