  3. Relieve fatigue

  4. Cause pain
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Analgesic drugs are pain killers. They are used to relieve pain. They act on central and peripheral nervous system. There are many group of analgesics such as simple analgesics (paracetamol and aspirin), non-steroidal anti inflammatory drugs (Ibuprofen and Naproxen Sodium) and opioids (morphine, pethidine). These drugs are sold under medical prescription and their long term use can develop tolerance in the body due to which the effectivity of drugs is used.
So, the correct answer is 'Relieve pain'.

Synthetic drugs structurally related to adrenaline are

  1. Amphetamines

  2. Barbiturates

  3. Analgesics

  4. Hallucinogens
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Amphetamines are synthetic stimulants commonly known as pep pills or anti-sleep drugs. They are structurally similar to adrenaline. Adrenaline is a neurotransmitter secreted from adrenal medulla in response to stress conditions in the body. They are used in dope test for athletes. They are stimulants of CNS (central nervous system). They speed up the messages transmitted between brain and body. They stimulate respiratory centre, suppress hunger and cause addiction. High doses of amphetamine cause sleeplessness and vomiting. 
So, the correct answer is 'Amphetamines'.

Stimulant that raises body temperature and blood pressure is

  1. Theobromine

  2. Theophylline

  3. Dexedrine

  4. Cocaine
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Theobromine is a bitter alkaloid which is found in cocoa plant (cocoa beans from which chocolate is prepared) and in tea leaves also. It belongs to class of xanthine alkaloids. It is a natural stimulant which stimulates nervous system and makes a person more active, alert and excited. It is a vasodilator and acts as a stimulant of heart. If theobromine is taken in excess amount, it raises heart beat, blood pressure and body temperature.
So, the correct answer is 'Theobromine'.

Stimulant present in betel nut is

  1. Caffeine

  2. Theobromine

  3. Arecoline

  4. Amphetamine
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Betel nut or areca nut is a fruit of palm tree. It is a mild stimulant because it contains an alkaloid arecoline. Arecoline is a bitter alkaloid and a stimulant of central nervous system (CNS). Stimulants make a person alert and active and increase the excitement. Arecoline mimics the receptors of nicotine in brain and thus, it can have parasympathetic effects also in the body. Generally betel nut is chewed with betel leaf to have a stimulating effect. 
So, the correct answer is 'Arecoline'.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The drug is a medicine or other substance which has a physiological effect when ingested or otherwise introduced into the body. 
  • After prolonged preadaptation or after stimulation with I.P. amphetamine the several measures of locomotor activity in rats was seen which includes the distance covered, movement time, speed of progression, and sinuosity showed significant changes in extreme situations. 
  • Hence, the drug affects Locomotory system.
  • So, the correct answer is 'Locomotory system'.

.............. is produced as a result of allergic reaction

  1. Histamine

  2. Nor-epinephrine

  3. Glucocorticoid

  4. Mineralocorticoid
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Histamine is a nitrogenous compound which gives a local immune response. Histamine is involved in the inflammatory response as well as it acts as a neurotransmitter. As a part of the immune response to foreign pathogens, histamine is produced by the mast cells and the basophil cells in the nearby connective tissue against the allergic reaction. Sneezing happens because of histamine-associated sensory neural stimulation.
