During Addison's disease:

Correct answer: B. MSH increases, cortical hormones decreases

  • A. MSH and cortical hormones increases
  • B. MSH increases, cortical hormones decreases
  • C. MSH and cortical hormones decreases
  • D. MSH decreases, cortical hormones increases

Explanation

In Addison's disease, the levels of MSH are often increased. This is because the pituitary gland is trying to compensate for the lack of cortisol by releasing more MSH. However, the increased levels of MSH do not have a significant effect on skin pigmentation.The levels of cortical hormones, such as cortisol and aldosterone, are decreased in Addison's disease. This is because the adrenal glands are not producing enough of these hormones.

About Coordination and Control

Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
