Pituitary Gland Hormone Identification

The question asks to identify the hormone secreted by the pituitary gland from the given options. The pituitary gland is a crucial endocrine gland that controls many bodily functions by producing and secreting hormones.

Hormone Secretion Sources

Let's analyze the origin of each hormone listed:

  • Growth hormone: Secreted by the anterior pituitary gland. It stimulates growth, cell reproduction, and regeneration.
  • Insulin: Secreted by the pancreas. It regulates glucose metabolism.
  • Adrenaline: Secreted by the adrenal glands (specifically the adrenal medulla). It is involved in the stress response.
  • Thyroxine: Secreted by the thyroid gland. It regulates metabolic rate.

Therefore, Growth hormone is the hormone secreted by the pituitary gland.
