Anterior Pituitary
The hypothalamus makes many hormones, even more than the pituitary gland. A couple of these are oxytocin and melatonin. It also makes many stimulating hormones that trigger the pituitary to make its hormones to control other glands.
Pituitary hormones directly control the release of hormones from other endocrine glands in the body, such as the thyroid, adrenal glands, and ovaries/testes. They also regulate growth, metabolism, stress response, and reproductive functions.
The hypothalamus is considered the control center of the endocrine system because it acts as the endocrine system's thermostat - it signals glands to turn on or off hormones as the body needs them.
The posterior pituitary is made up of axons belonging to cells called neurosecretory cells, whose cell bodies are in the hypothalamus. When these cell bodies are stimulated, the axons in the posterior pituitary releases their hormones into the blood stream. In a way, the posterior pituitary is an extension of the hypothalamus.
The endocrine gland that produces the most hormones is the anterior pituitary gland. This gland produces: -Growth Hormone (GH) -Lutenizing Hormone (LH) -Follicle-Stimulating Hormone (FSH) -Melanocyte-Stimulating Hormone (MSH) -Prolactin (PRL) -Adrenocorticotropic Hormone (ACTH) -Beta-endorphin
The pituitary gland. It makes more hormones that control other glands and body functions.
Very simply, the pituitary is considered the master gland because it sends instruction to other glands to produce their hormones. One of those is ACH, or adrenocorticotropic hormone. The pituitary sends it to the adrenal gland so it makes its hormones.
Oxytocin and Antidiuretic Hormone (vasopressin) are made in the hypothalamus but released from the posterior pituitary gland. Lutinising hormone, Folicle stimulating hormone, Thyroid stimulating hormone, Growth Hormone, Adreno-corticotropic hormone and prolactin are all made and secreted by the anterior pituitary gland. Oxytocin-releases milk from breast and maintains contractions in labour. Antidiuretic hormone- reduces the amount of water lost in urine LH+FSH- Sex hormones involved in menstral cycle and testosterone/oestrogen production. TSH - tells the thyroid to make more thyroxine- increases metabolism Growth hormone- Increases uptake of amino acids into cells, promotes growth via Insulin like growth factors. Prolactin makes the breasts produce milk.
The hypothalamus makes ADH and the posterior pituitary secretes it.
The pituitary gland releases growth hormone, which stimulates growth in children and adolescents. This hormone plays a crucial role in regulating bone and tissue growth throughout childhood and puberty. Additionally, the pituitary gland interacts with other glands to coordinate the body's overall growth and development.
The endocrine system makes and releases hormones in the body. Hormones are chemical messengers that travel through the bloodstream to target cells to regulate various physiological processes such as metabolism, growth, and reproduction. The endocrine system includes glands such as the pituitary, thyroid, adrenal, and pancreas.
The pituitary gland is often referred to as the master gland because it controls the function of many other endocrine glands in the body by releasing various hormones that regulate growth, metabolism, and reproduction.
