Question

Which one of the following statements about hormone is correct?

• A. Hormone produced by the ovary affects uterine contractions.
• B. Hormone produced by intestine stimulates heartbeat.
• C. Hormone produced by kidney regulates general blood pressure.
• D. Hormone produced by thyroid regulates general metabolism.

Answer 1

Answer: (D)

Oxytocin is produced by hypothalamus but stored and is released in to blood stream via posterior pituitary. It stimulates uterine contraction during child birth.

The emergency conditions activate the sympathetic motor nerve and make the adrenal medulla to release epinephrine and nor-epinephrine, which in turn increase the heart beat rate.

The endocrine parts of pancreas are islets of Langerhans that produce and secrete insulin and glucagon hormones. Insulin and glucagon maintain the general blood glucose level.

Thyroxine and triiodothyronine are thyroid hormone, which target all tissues and stimulate metabolic rate, growth and development.
