- Hypothalamus : Links the nervous system to the endocrine system via the pituitary gland. It controls the release of 8 hormones by the pituitary gland, controls body temperature, control of food and water intake, hunger and thirst!
- Pituitary gland : Produces essential hormones for everything living such as the growth hormone, adrenocorticotropic hormone, thyroid stimulating hormone, luteinizing hormone and follicle stimulating hormone, etc.
- Thyroid gland : Produces thyroid hormones that regulate the body metabolism, play an important role in bone growth and development of the brain and nervous system in children!
- Parathyroid glands : Release parathyroid hormone which plays a role in regulating calcium levels in the blood and bone metabolism.
