Question

Arrange in order the steps involved in the changes that occur during puberty.1. Triggering of GnRH by the hypothalamus2. Movement of GnRH through a network of capillaries to the anterior pituitary gland3.Stimulation of production and secretion of FSH and LH4. Stimulation of the gonadal response

Answer 1

During puberty, the hypothalamus triggers the release of GnRH, which travels to the pituitary gland, stimulating the production of FSH and LH. These hormones then stimulate the gonads, leading to the maturation of reproductive organs and development of secondary sex characteristics.

Step-by-step explanation:

During puberty, the changes that occur in the body are triggered by the hypothalamus in the brain. The steps involved in these changes are as follows:

1. Triggering of GnRH by the hypothalamus: The hypothalamus releases gonadotropin-releasing hormone (GnRH) in pulses.
2. Movement of GnRH through a network of capillaries to the anterior pituitary gland: The GnRH travels to the anterior pituitary gland, which is located at the base of the brain.
3. Stimulation of production and secretion of FSH and LH: The GnRH stimulates the anterior pituitary gland to produce and secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
4. Stimulation of the gonadal response: FSH and LH travel through the bloodstream to the gonads (testes in males and ovaries in females), where they stimulate the production of sex hormones (estrogen in females and testosterone in males), leading to the maturation of the reproductive organs and the development of secondary sex characteristics.

These steps occur in a specific sequence and are responsible for the physical changes that take place during puberty.

Answer 2

The steps involved in the changes that occur during puberty include triggering of GnRH by the hypothalamus, movement of GnRH to the anterior pituitary gland, stimulation of FSH and LH production and secretion, and stimulation of the gonadal response.

Step-by-step explanation:

The changes that occur during puberty involve several steps:

1. The hypothalamus triggers the release of gonadotropin-releasing hormone (GnRH).
2. GnRH travels through a network of capillaries to the anterior pituitary gland.
3. The anterior pituitary gland is stimulated to produce and secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
4. FSH and LH stimulate the gonads (testes in males and ovaries in females) to respond and produce sex hormones.

These changes in hormone production and secretion lead to the development of secondary sex characteristics, maturation of the reproductive organs, and initiation of processes like spermatogenesis and folliculogenesis.
