Which one of the following is not a gonadotropin hormone?
Correct answer: A. Oxytocin
- A. Oxytocin
- B. Leutinizing Hormone
- C. Human Chorionic Gonadotropin
- D. Follicle Stimulating Hormone
Explanation
Gonadotropins are hormones that are synthesized and secreted by the anterior pituitary gland and act on the gonads to stimulate hormone production. These hormones include Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), and the placental hormone Human Chorionic Gonadotropin (hCG). Oxytocin is not a gonadotropin. It is produced by the hypothalamus and stored and secreted by the posterior lobe of the pituitary gland. It stimulates uterine contractions during labour and causes dilation of the milk ducts of the mammary glands to promote milk ejection.

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.
