Correct answer: A. LH
- A. LH
- B. FSH
- C. Progesterone
- D. Estradiol
Explanation
LH causes the ovulation and secretion of progesterone and oestrogen from ovarian follicles and corpus luteum. It is secreted by the anterior pituitary lobe at the end of the proliferative stage (day 14). In response to sudden release of LH from anterior pituitary lobe, egg from the mature follicle is released into the oviduct. The event is known as ovulation.

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.
