Understanding the Endocrine System: Glands, Hormones, and Functions

• The endocrine system is a collection of glands that produce hormones to regulate body functions.
• Major endocrine glands include the hypothalamus, pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries, and testes.
• The endocrine system works in a feedback loop, with the hypothalamus releasing hormones that stimulate the pituitary gland to release other hormones.
• The pituitary gland produces and secretes hormones that control growth, reproduction, metabolism, and stress response.
• The pituitary gland is divided into the anterior pituitary and posterior pituitary, with each producing different hormones.
• Hormones produced by the anterior pituitary include growth hormone, thyroid-stimulating hormone, adrenocorticotropic hormone, follicle-stimulating hormone, luteinizing hormone, and prolactin.
• Hormones produced by the posterior pituitary include antidiuretic hormone and oxytocin.
• The pineal gland produces melatonin, a hormone that regulates the sleep-wake cycle and plays a role in regulating puberty.
• The thyroid gland produces thyroxine and triiodothyronine, which regulate metabolism, heart rate, blood pressure, growth, development, body temperature, bone health, and cognitive function.
• The pituitary gland regulates the thyroid gland through thyroid-stimulating hormone.
• Thyroid hormones are made up of iodine and tyrosine, with T4 being the main hormone produced and converted to T3 in the body's tissues.
• Thyroid hormones increase the rate at which cells use oxygen and produce energy, and play a role in growth, development, reproduction, and cognitive function.
