Glands

• Endocrine cells release their products (hormones) directly into the extracellular fluid or bloodstream to travel to target tissues where they bind with specific receptors on other cells.
• Hormones are chemical messengers produced by specialized cells called endocrine cells, which can be found throughout the body.
• The endocrine system is made up of glands that secrete hormones directly into the bloodstream.
• Examples of endocrine organs include the pituitary gland, thyroid gland, adrenal glands, pancreas, ovaries/testes, and hypothalamus.
• The hypothalamus acts as an intermediary between the nervous system and the endocrine system, regulating many bodily functions through its control over the pituitary gland.
• Examples of endocrine organs include the pituitary gland, thyroid gland, adrenal glands, pancreas, ovaries/testes, and hypothalamus.
• The nervous system uses electrical signals to communicate between neurons, while the endocrine system uses chemical signals known as hormones.
• The pituitary gland secretes several hormones, including growth hormone, prolactin, follicle-stimulating hormone, luteinizing hormone, thyrotropin, melanocyte-stimulating hormone, corticotrophin, and antidiuretic hormone.
• The endocrine system regulates various bodily functions such as growth, metabolism, reproduction, sexual development, sleep-wake cycles, stress response, water balance, and blood pressure.
• Examples of endocrine organs include the pituitary gland, thyroid gland, adrenal glands, pancreas, ovaries/testes, and pineal gland.
