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

1. Endocrine gland - Anterior pituitary;
   Hormone-Oxytocin;
   Function/deficiency symptoms - Stimulates uterus contraction during childbirth
2. Endocrine gland - Posterior pituitary;
   Hormone-Growth Hormone (GH);
   Function/deficiency symptoms-Oversecretion stimulates abnormal growth
3. Endocrine gland -Thyroid gland;
   Hormone-Thyroxine;
   Function/deficiency symptoms-Lack of iodine in diet results in goiter
4. 
   Endocrine gland -Corpus luteum;
   Hormone-Testosterone;
   Function/deficiency symptoms-Stimulates spermatogenesis
