Explanation / Answer
1.The alkaloids presents in Atropa belladonna has toxic anti cholinergic effects on body.It affects both CNS and PNS causing effects like acute delirium, hallucination, tachycardia, vomiting, dry mouth, flushed skin and blurred vision.
Atropine blocks muscarnic receptor acetylcholine which plays an important role in the functioning of brain for learning, memory and orientation.
Muscarnic antagonists are used as bronchodilators in asthama treatment.
2.Based on the information that is transported from tounge to brain the sense of taste works.Taste is mainly known by the basal cells and papille that are present on the tounge When there are no basal cells, the taste cannot be recognised by the tounge and cannot be sensed to brain.The substances with different tastes are released from basal cells in the taste buds or they enter from the blood.
In aged people, the sense of taste may be less sensitive because the cells in taste buds are not regenerative as quickly as in young people.
