Answer:
Podemos suponer que este estudiante tiene insuficiencia de la hormona de crecimiento (somatotropina) que la secreta la glándula hipófisis y se encuentra en la base del cerebro. Esta hormona no ingresa a las células en su mecanismo de acción por ser peptídica o no esteroidea.

On falling of the sugar level pancreas releases a hormone called glucagon. This glucagon informs the pancreas about the presence of low sugar in blood, after which it releases the stored glucose, and helps in raising the blood sugar level. Alpha cell of pancreas produces glucagon.
