NEET 2011 Biology question
Given below is an incomplete table about certain hormones, their source glands and one major effect of each on the body in humans. Identify the correct option for the three blanks A, B and C.
Table (GLAND - SECRETION - EFFECT ON BODY)
Row 1: Gland = A; Secretion = Oestrogen; Effect on body = Maintenance of secondary sexual characters
Row 2: Gland = Alpha cells of islets of Langerhans; Secretion = B; Effect on body = Raises blood sugar level
Row 3: Gland = Anterior pituitary; Secretion = C; Effect on body = Over secretion leads to gigantism
Solution
A: oestrogen is mainly secreted by the ovary (the growing follicles) and maintains the secondary sexual characters in females, so A is ovary. B: the alpha cells of the islets of Langerhans secrete glucagon, which raises blood glucose by promoting glycogenolysis and gluconeogenesis
