The major moto of Pharmatricks Question and Answer (PTQA) is to revise the concepts in a very short period of time. The question level will go from basic to advanced as you start moving down the questions. It will be helpful for these students who have brief ideas about the questions. Practicing this will clear most of the doubt among the students. Our Target is to make available maximum 500 PTQA questions on each chapter to make the students completely understand the concepts. It will be updated regularly. So keep visiting the website for more questions.
The question and answer in this session will contain the concepts of Autonomic Nervous System (ANS). At, present we have brought 40 question from the topic. It will be updated soon.
Here is your answer, Now do the same with all other boxes
Central and peripheral
Autonomic and somatic
Parasympathetic and sympathetic
Parasympathetic have longer preganglionic fibers.
Parasympathetic nervous system
Sympathetic nervous system
Yes, it is possible.On such cases the total control of activity is determined by algebraic sum of both sympathetic and parasympathetic activity.
Cranio sacral
Dorso lumbar
Acetyl choline
Noradrenaline
Nicotinic and Muscarinic
Ganglia and Adrenal medula
Stomach and Instestinal muscle
Heart and CNS
GIT, Bronchus, Bladder, Eyes
Ligand gates ion channel
Neuromuscular junction (skeletal muscle)
Phenyl methyl ammonium
Tubocurarine
Dimethyl phenyl piperazinium
Hexamethonium
G-protein Coupled receptor
Acetyl choline
Quaternary ammonium compound
Cholinesterase
Acetyl CoA and Choline
hemicholinium
botulinum toxin
vesamicol
choline acetyltransferase
It stimulate release of Nitric Oxide
It can dilate the blood vessel and has vasodilatory action.
Yes, the major neurotransmitter for parasympathetic nervous system is Ach.
Ach promote parasympathetic activity (Rest). So, it will decrease the heart rate, force of contraction and AV conduction of heart
Ach stimulate the release of Nitric Oxide. So, it will dilate the blood vessel and can have vasodilatory action.
Remember Ach promotes parasympathetic activity (Rest). It will promote digestion activity like increase GI secretion and Peristaltic movement.
Ach promote parasympathetic activity (Rest). It will promote urination as no one can pee while running or doing flight and fight activity.
Ach promote parasympathetic activity. So, more air is not required in comparison to running while at rest. It will cause Bronchoconstriction
Ach release can cause Vasodilatory action for blood vessel and Bronchoconstriction for Bronchus.
