​(b) "Both overproduction and underproduction of growth hormone leads to disorders in the body". Explain.

Answer 1

(a)

Function of cerebellum − It helps to maintain posture, equilibrium, and coordination in voluntary movements.

Function of medulla −It helps to control our involuntary muscles such as cardiac, respiratory, etc. It controls the activities of internal organs

(b) Growth hormones are required for the proper development of the body. Oversecretion or undersecretion of this hormone can lead to various types of abnormalities.
The two abnormalities associated with growth hormone are dwarfism and gigantism.
Dwarfism is caused when the growth hormone is not secreted in required amount whereas the over secretion of the growth hormone results in gigantism.
