Reproductive system part 3 video

What is the central control of the reproductive system?

The central control of the reproductive system originates in the hypothalamus and anterior pituitary gland.

Which hormone from the hypothalamus stimulates the release of FSH and LH from the pituitary gland?

Gonadotropin-releasing hormone (GnRH)

What are the collective names for FSH and LH?

Gonadotropins

Which organs do FSH and LH act on in both males and females?

Gonads (ovaries in females, testes in males)

What hormones are produced by the ovaries in females?

Estrogen, progesterone, relaxin, and inhibin

How long is the typical cycle in which hormonal regulation occurs in females?

28-day cycle

What governs the ovarian events, leading to the ovarian cycle's monthly patterns?

Hypothalamic-pituitary-ovarian pathway

What do hormonal fluctuations from the ovary influence in females?

Changes in the uterus, known as the uterine cycle

Which hormone stimulates follicular development in the ovary?

Follicle-stimulating hormone (FSH)

What is the process called that involves the release of a secondary oocyte from the mature follicle?

Ovulation

What is formed from the remnants of the mature follicle after ovulation?

Corpus luteum

What is the role of LH Surge in ovulation?

Triggers ovulation and facilitates the release of the mature oocyte.

How is the 28-Day Cycle divided in relation to ovulation?

Pre-ovulatory and post-ovulatory phases, with ovulation occurring midway.

What is the primary role of Luteinizing Hormone (LH) in the menstrual cycle?

Responsible for triggering ovulation and forming the corpus luteum.

What happens to the Corpus Luteum at the end of the cycle?

regresses and transforms into the corpus albicans, leading to reduced hormone production

Which phase of the ovarian cycle involves corpus luteum formation and hormone secretion?

Luteal Phase

What is the role of Estrogen in the uterine cycle?

Drives endometrial thickening in the proliferative phase, preparing the uterus for potential embryo implantation.

What initiates menstruation in the menstrual cycle?

Breakdown of the functional layer of the endometrium

Which phase of the menstrual cycle follows menstruation and includes ovulation?

Secretory phase

What is the role of Human Chorionic Gonadotropin (HCG) in sustaining the corpus luteum?

Preventing its regression and maintaining hormone production

How does Human Chorionic Gonadotropin (HCG) support pregnancy progression?

Inhibiting menstruation and releasing the uterus from hypothalamic control

Which hormone prompts the ovaries to secrete increasing levels of estrogen in the pre-ovulatory phase?

Follicle-stimulating hormone (FSH)

What triggers ovulation by causing a surge around mid-cycle?

Luteinizing hormone (LH)

Which hormone maintains the endometrium and readies the uterus for potential embryo implantation?

Progesterone

What signifies the end of progesterone dominance and the initiation of a new menstrual cycle?

The decline of the corpus luteum
