Question

Select the answer which correctly matches the endocrine gland with the hormone it secretes and its functions/deficiency symptom:

• A. Endocrine gland - Anterior pituitary;
  Hormone-Oxytocin;
  Function/deficiency symptoms - Stimulates uterus contraction during childbirth
• B. Endocrine gland - Posterior pituitary;
  Hormone-Growth Hormone (GH);
  Function/deficiency symptoms-Oversecretion stimulates abnormal growth
• C. Endocrine gland -Thyroid gland;
  Hormone-Thyroxine;
  Function/deficiency symptoms-Lack of iodine in diet results in goiter
• D.
  Endocrine gland -Corpus luteum;
  Hormone-Testosterone;
  Function/deficiency symptoms-Stimulates spermatogenesis

Answer 1

The correct option is C Endocrine gland -Thyroid gland;

Hormone-Thyroxine;
Function/deficiency symptoms-Lack of iodine in diet results in goiter
Thyroxine, secreted by the thyroid gland, helps control metabolism and regulates body temperature by calorigenic action. Inadequate intake of iodine in the diet causes goitre.
Growth hormone (GH) or Somatotrophic hormone (STH), secreted by adenohypophysis or anterior lobe of pituitary gland, stimulates growth by stimulating protein synthesis. Over secretion of the hormone results in abnormal growth or gigantism.
Oxytocin, secreted by neurohypophysis or the posterior lobe of the pituitary gland, stimulates secretion of milk from mammary glands and causes contractions of the uterus at the time of childbirth.
Testosterone, secreted by the testis, affects the normal development and functions of secondary sexual organs and characters in males and stimulates the formation of sperms.
