Question
Name the hormone that is secreted from the thyroid gland and write down what may happen if hypo or hypersecretion takes place.
Answer
The hormone secreted from the thyroid gland is thyroxine or T4. If there is hyposecretion of thyroxine, it may lead to a condition called hypothyroidism, causing symptoms like weight gain, fatigue, and cold intolerance. Hypersecretion of thyroxine can cause hyperthyroidism, leading to symptoms such as weight loss, rapid heartbeat, and sweating.
