A hormone is known to cause smooth muscle relaxation in blood vessels. However, it also causes contraction of cardiac muscle. What statement below would be true of this hormone?
A. it acts through paracrine signalling in the heart, but the blood vessels undergo endocrine signalling
B. the blood vessels have a different receptor for this hormone than the heart does
C. the heart is a target cell of this hormone, but not the blood vessels
D. this is not possible as hormones have the same effect on all target organs
Homework Answers
Option b is the correct answer as this usually occur in our body especially in cardiovascular system. The receptor in which the hormones acting will determine what kind of action is to occur .
Option A,c and d are wrong as there is such type of hormones and hormone produce effect in different receptors

The neurotransmitter acetylcholine (ACh) causes the rapid contraction of skeletal muscle and the slower relaxation of cardiac muscle. Which one of the following is the most likely explanation for this difference? A. ACh activates a GPCR pathway in cardiac muscle and an ion channel coupled receptor in skeletal muscle. B. ACh activates an ion channel coupled receptor in cardiac muscle and a GPCR pathway in cardiac muscle. C. ACh is permeable through the plasma membrane of skeletal muscle cells but...
