In breastfeeding mothers, which hormone would be at an increased level?

Correct answer: A. Prolactin

  • A. Prolactin
  • B. Thyroxin
  • C. Aldosterone
  • D. Insulin

Explanation

Prolactin is a hormone produced by the pituitary gland that plays a crucial role in lactation and breastfeeding. During pregnancy and breastfeeding, prolactin levels increase significantly, stimulating the growth of milk-producing cells in the breast and initiating milk production. In breastfeeding mothers, prolactin levels remain elevated to maintain milk production and support lactation. Frequent suckling by the baby stimulates the release of prolactin, ensuring a continuous supply of milk.

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.
