Which of the following hormones is released by the posterior lobe of the pituitary gland?
Correct answer: A. Antidiuretic hormones
- A. Antidiuretic hormones
- B. Growth hormone
- C. Estrogen
- D. Prolactin
Explanation
Option A is correct. The posterior lobe of the pituitary gland releases antidiuretic hormone (ADH). ADH is also known as vasopressin. It is a hormone that helps the body retain water. ADH is released when the body's fluid levels are low. It acts on the kidneys to cause them to reabsorb more water from the urine. This helps to increase the body's fluid levels and prevent dehydration. The other options are not hormones that are released by the posterior lobe of the pituitary gland: Growth hormone is released by the anterior lobe of the pituitary gland. Estrogen is a female sex hormone that is produced by the ovaries and other tissues in the body. Prolactin is a hormone that is produced by the anterior lobe of the pituitary gland. It stimulates milk production in women.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
