a body system involved in stress responses
produces hormones that regulate metabolism, body heat, and bone growth
located anterior to trachea but inferior to the larynx
produces t3 and t4

four small glands on the posterior of the thyroid gland
regulates blood calcium levels - so controls excitability of neurones
A hormone of the parathyroid gland that regulates the metabolism of calcium and phosphorus in the body.
inhibits osteoblasts- deposits bones so uses up calcium
