A pregnant female delivers a baby, who suffers from stunted growth mental retardation low intelligence quotient and abnormal skin. This is the result of

Which of the following statement is correct in relation to the endocrine system?

  • Adenohypophysis is under direct neural regulation of the hypothalamus

  • Organs in the body like gastrointestinal tract. heart, kidney and liver do not produce any hormones

  • Non-nutrient chemicals produced by the body in trace amount that act as intercellular messenger are known as hormones

  • Releasing and inhibitory hormones are produced by the pituitary gland

Select the answer which correctly matches the endocrine gland with the hormone it

secretes and its function/deficiency symptom

Which one of the following pairs of hormones are the examples of those that can easily

pass through the cell membrane of the target cell and bind to a receptor inside it (mostly

in the nucleus)?

  • Insulin and glucagon

  • Thyroxin and insulin

  • Somatostatin and oxytocin

  • Cortisol and testosterone

What is correct to say about the hormone action in humans?

  • Glucagon is secreted by β-cells of islets of Langerhans and stimulates glycogenolysis
  • Secretion of thymosine is stimulated with ageing.
  • In females, FSH first binds with specific receptors on ovarian cell membrane
  • FSH stimulates the secretion of oestrogen and progesterone
