5 Questions
Describe the components of the reproductive system.
The reproductive system consists of the male and female reproductive organs, hormones, and supporting structures such as the hypothalamus and pituitary gland.
What are the hormones that regulate the reproductive system?
The hormones that regulate the reproductive system include GnRH (Gonadotropin-releasing hormone), FSH (Follicle stimulating Hormone), LH (Luteinising hormone), Oestrogen, Progesterone, and Prolactin releasing hormone (PRH).
Explain the mode of action of the contraceptive pill, including the combined and the progesterone only pill.
The contraceptive pill works by inhibiting ovulation through the suppression of FSH and LH, and by thickening the cervical mucus to prevent sperm from reaching the egg. The combined pill contains synthetic versions of estrogen and progesterone, while the progesterone-only pill contains only synthetic progesterone.
What are the events following fertilization?
Following fertilization, the zygote undergoes cleavage to form a blastocyst, which implants in the endometrium. The blastocyst then develops into an embryo and eventually a fetus.
Discuss the hormonal changes during a female reproductive cycle.
The hormonal changes during the female reproductive cycle involve the release of GnRH from the hypothalamus, which stimulates the release of FSH and LH from the pituitary gland. These hormones then regulate the maturation of follicles, ovulation, and the development of the corpus luteum, which produces estrogen and progesterone.
Study Notes
- The text discusses reproductive system therapeutics under the field of Pharmacotherapeutics.
- Dr. Shaymaa ElBahy builds on the foundation laid in Year 1.
- Components of the reproductive system include the male and female reproductive systems, hormones, and their regulation.
- Male and female reproductive systems consist of specific structures, hormones, and functions.
- Hormones like gonadotrophin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) play essential roles.
- Female reproductive cycle includes various hormonal changes, including those leading to ovulation and menstruation.
- Sex determination and differentiation involve key hormones and processes.
- Following fertilization, the zygote undergoes cell division and implants into the uterine wall, leading to parturition and hormonal changes.
- In Year 2, the text covers pathophysiology, hormone functions and actions, and various contraceptive methods.
- The hypothalamus plays a role in releasing hormones like GnRH and prolactin-releasing hormone (PRH).
- Hormones such as FSH, LH, estrogen, and progesterone regulate the reproductive system.
- The menstrual cycle is related to the actions of these reproductive hormones.
- The contraceptive pill, including combined and progesterone-only pills, functions by altering the hormonal balance to prevent ovulation.
- Hormone glossary includes terms like endometrium, Graafian follicle (GF), corpus luteum (CL), and the hypothalamus and pituitary hormones.
