Question

In experiments where researchers suspect that a hormone may be responsible for a certain physiological effect, they may cut the neurons leading to the organ where the effect being studied occurs. What is the purpose of cutting these neurons?
A) to make sure that the effect is not occurring through actions in the nervous system
B) to make sure that the organ being affected cannot function unless the researchers stimulate it with an external electrical probe
C) to impair the normal functions of the organ so that the hormonal effect can be more easily studied
D) to numb the organ so that it can be probed without inducing pain in the lab animal

Answer 1

Answer:

A) To make sure that the effect is not occuring through actions in the nervous system

Explanation:

In the above scenario, researchers actually studies the effect of hormone to the organ but they are in a situation to study the effect on organ are either hormone base or nervous system base (neurons). For this reason they will cut the neurons to study the effect of hormone on the organ.

So, to check the effect of hormone they should cut the neurons to make sure these effect are not due to actions of nervous system.

Answer 2

Answer:

A) to make sure that the effect is not occurring through actions in the nervous system

Explanation:

The endocrine system secretes hormones whose function is to connect the nervous system with different parts of the body. Moreover, neurotransmitters are hormone-like molecules that are secreted by both neural and non-neural cells and play analogous functions to the hormones secreted by the endocrine system
