1. Hormones are chemical messengers produced from ductless endocrine glands. 2. Hyposecretion of thyroxine causes myxoedema (sluggish metabolism, and swelling on face, hands and body) in adults. 3. Glucagon is antagonistic to insulin. It stimulates breakdown of stored glycogen into glucose, to raise glucose level in blood. 4. Growth hormone (GH) secreted by anterior pituitary is essential for normal growth. 5. Hormones secreted by the adrenal cortex are called cortical hormones or corticoids. It regulates metabolism of nutrients (carbohydrates, proteins and fats), salt-water balance and amount of urine formed. Column A Column B 1. Hormone (c) Endocrine gland 2.
