1. Pituitary Gland: Located at the base of the brain, it's often called the "master gland" because it controls many other endocrine glands.
2. Thyroid Gland: Located in the neck, it produces hormones that regulate metabolism.
3. Parathyroid Glands: Four small glands located near the thyroid, they regulate calcium levels in the blood.
4. Adrenal Glands: Two glands located on top of the kidneys, they produce hormones like adrenaline and cortisol that help the body respond to stress.
5. Pancreas: An organ in the abdomen, it produces insulin and glucagon, which regulate blood sugar levels.
6. Ovaries (female): Located in the pelvic region, they produce estrogen and progesterone, which regulate the female reproductive system.
7. Testes (male): Located in the scrotum, they produce testosterone, which regulates the male reproductive system.
8. Pineal Gland: Located deep within the brain, it produces melatonin, a hormone that regulates sleep cycles.
Note: Some sources may include the thymus gland, which is located in the chest and plays a role in immune system development. However, the thymus is often considered a lymphoid organ rather than a strictly endocrine gland.
