Select the answer which correctly matches the endocrine gland with the hormone it secretes and its function/deficiency symptom : Endocrine gland - Posterior pituitary, Hormone - Growth Hormone (GH), Function/deficiency symptoms - Oversecretion stimulates abnormal growth Endocrine gland - Thyroid gland, Hormone - Thyroxine, Function/deficiency symptoms - Lack of iodine in diet results in goitre Endocrine gland - Anterior pituitary, Hormone - Oxytocin, Function/deficiency symptoms - Stimulates uterus contraction during child birth Endocrine gland - Corpus luteum, Hormone - Testosterone, Function/deficiency symptoms - stimulates spermatogenesis None 15. The pineal gland secretes a hormone progesterone which helps to regulate sleep pattern. Thyroid glands release hormone which regulate the level of calcium in the blood with the help of calcitonin which is produced in the parathyroid glands. Select the correct option regarding the given paragraph.i) Positions of pineal and parathyroid should be interchangedii) Progesterone must be replaced by melatoniniii) Parathyroid should not be replaced as it is correctly mentioned.iv) Positions of progesterone and calcitonin should be interchangedv) Positions of thyroid and parathyroid should be interchanged i, ii and v only ii and v only ii and iv only i and iii only None 16.
