Thyroid hormone synthesis and physiology - UpToDate

Regulation of the reproductive system is a process that requires the action of hormones from the pituitary gland, the adrenal cortex, and the gonads. During puberty in both males and females, the hypothalamus produces gonadotropin-releasing hormone (GnRH), which stimulates the production and release of and luteinizing hormone (LH) from the anterior pituitary gland. These hormones regulate the gonads (testes in males and ovaries in females) and therefore are called . In both males and females, FSH stimulates gamete production and LH stimulates production of hormones by the gonads. An increase in gonad hormone levels inhibits GnRH production through a negative feedback loop.

Pathways of thyroid hormone (TH) metabolism

In females, FSH stimulates development of egg cells, called ova, which develop in structures called follicles. Follicle cells produce the hormone inhibin, which inhibits FSH production. LH also plays a role in the development of ova, induction of ovulation, and stimulation of estradiol and progesterone production by the ovaries, as illustrated below. Estradiol and progesterone are steroid hormones that prepare the body for pregnancy. Estradiol produces secondary sex characteristics in females, while both estradiol and progesterone regulate the menstrual cycle.

It synthesizes and secretes certain neurohormones, called releasing or hypothalamic hormones, and these in turn stimulate or inhibit the secretion of pituitary hormones.

The insulae are believed to be involved in and play a role in diverse functions usually linked to or the regulation of the body's , which is the metabolic equilibrium actively maintained by several complex biological mechanisms that operate via the autonomic nervous system to offset disrupting changes.

Synthesis of thyroid hormones is a complex multi-step process which possesses steps that occur within the follicular epithelial cells and also within the acellular follicular lumen.

Importantly, peroxidase-processed thyroglobulin within the follicle can act as a reservoir for thyroid hormones in the absence of stimulation for hormone release.

Hormones have a wide range of effects and modulate many different body processes. The key regulatory processes that will be examined here are those affecting blood glucose, hunger, metamorphosis, stress, and sex. We will primarily focus on these processes in vertebrates, but will also consider invertebrates in some cases.

Chapter 2 Thyroid Hormone Synthesis And Secretion

In response to high levels of leptin, the hypothalamus releases thyrotropin-releasing hormone, signals to the anterior pituitary to release thyroid-stimulating hormone. The thyroid the releases thyroxine, also known as tetraiodothyronine or T4, and triiodothyronine, also known as T3. These hormones affect nearly every cell in the body except for the adult brain, uterus, testes, blood cells, and spleen. T3 and T4 activate genes involved in energy production and glucose oxidation, resulting in increased rates of metabolism and body heat production which together cause an increased rate of caloric usage. Low levels of leptin cause the opposite response, leading to a decreased metabolic rate to conserve energy.

thyroxine promotes the effects of growth hormone on protein synthesis

Unlike plant hormones, animal hormones are often (though not always) produced in specialized hormone-synthesizing glands (shown below). The hormones are then secreted from the glands into the blood stream, where they are transported throughout the body. There are many glands and hormones in different animal species, and we will focus on just a small collection of them.
