In a human female, the reproductive phase starts on the onset of puberty and ceases around middle age of the female. Study the graph given below regarding menstrual cycle and answer the questions that follow :

 

Name the hormones and their source organ, which are responsible for menstrual cycle at puberty.

Ans.  At puberty, the menstrual cycle is regulated by hormones produced by various organs:

  1. Follicle-stimulating hormone (FSH): Produced by the anterior pituitary gland.

  2. Luteinizing hormone (LH): Also produced by the anterior pituitary gland.

  3. Estrogen: Produced primarily by the ovaries, specifically by the developing follicles.

  4. Progesterone: Produced primarily by the ovaries, specifically by the corpus luteum.

These hormones play crucial roles in regulating the menstrual cycle, including follicular development, ovulation, and the maintenance of the uterine lining.
