Answer 1

Answer: (A)

A- 1, B- 3, C- 2, D- 4

Oxytocin - Milk ejection hormone

Oxytocin is a mammalian hormone that also acts as a neurotransmitter in the brain.

In women, it is released mainly after distension of the cervix and vagina during labor, and after stimulation of the nipples, facilitating birth and breastfeeding, respectively.

Glucagon - Increases blood glucose

Glucagon strongly opposes the action of insulin; it raises the concentration of glucose in the blood by promoting glycogenolysis, which is the breakdown of glycogen (the form in which glucose is stored in the liver), and by stimulating gluconeogenesis, which is the production of glucose.

Adrenaline - Increase in heart rate

Epinephrine, more commonly known as adrenaline, is a hormone secreted by the medulla of the adrenal glands. Strong emotions such as fear or anger cause epinephrine to be released into the bloodstream, which causes an increase in heart rate, muscle strength, blood pressure, and sugar metabolism.

Thyroxine - Controls BMR

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It is the inactive form and most of it is converted to an active form called triiodothyronine by organs such as the liver and kidneys.

Thyroid hormones play vital roles in regulating the body’s metabolic rate, heart and digestive functions, muscle control, brain development and maintenance of bones.

Therefore, the correct answer is option A.
