releasing hormones come from which one of the following?
528621
The main releasing hormones are as follows: The hypothalamus uses thyrotropin-releasing hormone (TRH or thyroliberin) to tell the pituitary to release thyrotropin. The hypothalamus uses corticotropin-releasing hormone (CRH or corticoliberin) to tell the pituitary to release corticotropin.

Follicle-stimulating hormone (FSH) is a glycoprotein gonadotropin secreted by the anterior pituitary in response to gonadotropin-releasing hormone (GnRH) released by the hypothalamus. The pituitary gland also secretes luteinizing hormone (LH), another gonadotropin.

While the nervous system uses neurotransmitters as its chemical signals, the endocrine system uses hormones. The pancreas, kidneys, heart, adrenal glands, gonads, thyroid, parathyroid, thymus, and even fat are all sources of hormones.

Gonadotropin-releasing hormone (GnRH) is a releasing hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. GnRH is a tropic peptide hormone synthesized and released from GnRH neurons within the hypothalamus.
1264999
GnRH is a hormone produced in the hypothalamus region of the brain. GnRH moves through the bloodstream to the pituitary gland. There, it binds to certain receptors. Those receptors signal the pituitary gland to create two more hormones: LH and follicle-stimulating hormone (FSH).

Growth hormone is a protein hormone of about 190 amino acids that is synthesized and secreted by cells called somatotrophs in the anterior pituitary.

The anterior lobe of your pituitary gland is made up of several different types of cells that produce and release different types of hormones, including: Growth hormone. Growth hormone regulates growth and physical development. It can stimulate growth in almost all of your tissues.

What is growth hormone? Growth hormone is released into the bloodstream from the anterior pituitary gland. The pituitary gland also produces other hormones that have different functions from growth hormone. Growth hormone acts on many parts of the body to promote growth in children.

Growth hormone-releasing hormone is a hormone produced in the hypothalamus. The main role of growth hormone-releasing hormone is to stimulate the pituitary gland to produce and release growth hormone into the bloodstream. This then acts on virtually every tissue of the body to control metabolism and growth.
1383468
Endocrine glands - secrete chemical substances called hormones directly into the bloodstream for transport to target tissues. ... Most of the hormones are proteins. ie. calcittonin from the thyroid gland and the hormones from the pituitary gland, pancreas, and the parathyroid glands.

Ovaries. The ovaries produce and release eggs (oocytes) into the female reproductive tract at the mid-point of each menstrual cycle. They also produce the female hormones oestrogen and progesterone.
1075114
HGH Peptides, also known as Growth Hormone Releasing Peptides, interact with the hypothalamus and pituitary gland to naturally increase Growth Hormone levels in the body. Peptides encourage the secretion of HGH and communicate with the body to produce and release your naturally occurring growth hormone.

These hormones, in turn, alert the adrenal glands to produce corticosteroid hormones. Glucocorticoids released by the adrenal cortex include: Hydrocortisone: Commonly known as cortisol, it regulates how the body converts fats, proteins, and carbohydrates to energy.

Summary. Exocrine glands secrete their products directly into ducts, whereas endocrine glands release their products (hormones) into the bloodstream.

Neurosecretory cells in the hypothalamus release oxytocin (OT) or ADH into the posterior lobe of the pituitary gland. These hormones are stored or released into the blood via the capillary plexus.

1) Protein hormones (or polypeptide hormones) are made of chains of amino acids. An example is ADH (antidiuretic hormone) which decreases blood pressure. 2) Steroid hormones are derived from lipids. Reproductive hormones like testosterone and estrogen are steroid hormones.
