Hormonal Control of Reproduction

These flashcards cover key concepts related to hormonal control of reproduction, including definitions, functions, and locations of hormones.

What is the definition of hormones?

Hormones are chemical messengers that travel via circulation to elicit specific effects.

What characterizes the presence of hormones in circulation?

Hormones are present in circulation in low amounts.

What is the role of the hypothalamus in hormonal control?

The hypothalamus is the central neural control center for reproductive hormones.

Which hormones stimulate the release of LH and FSH?

Gonadotropin Releasing Hormone (GnRH) from the hypothalamus stimulates the release of LH and FSH.

What is the target and function of Oxytocin?

Oxytocin targets the smooth muscle of the reproductive tract and stimulates muscle contraction.

What two centers in the hypothalamus are important for reproductive hormone regulation?

The Surge Center and Tonic Center are crucial for regulating reproductive hormones.

What are gonadotropins, and where are they synthesized?

Gonadotropins are hormones synthesized and secreted by gonadotrophs in the anterior pituitary.

What is one main function of Follicle Stimulating Hormone (FSH)?

FSH stimulates follicular development and estradiol synthesis in the ovaries.

What hormones are secreted by the anterior pituitary?

The anterior pituitary secretes gonadotropins including LH, FSH, and Prolactin.

How does Oxytocin function in both males and females?

In males, it causes smooth muscle contraction; in females, it stimulates milk production and uterine contractions.
