The thyroid gland is a butterfly-shaped organ located in the front of the neck, below the voice box. It is made up of two lobes, each connected to the trachea by a small duct.
The thyroid gland has three main lobes:
Central lobe: This lobe is responsible for the majority of hormone production.
Parathyroid glands: These glands are responsible for regulating calcium and phosphate levels in the body.
Parathyroid glands: These glands are responsible for regulating calcium and phosphate levels in the body.
The thyroid gland is made up of small, cone-shaped cells called C cells. The C cells are responsible for producing hormones that regulate metabolism. These hormones include thyroxine (T4) and triiodothyronine (T3).
Thyroxine is responsible for controlling metabolism. When the body has low levels of T4, the thyroid gland produces more T4 hormones. This helps to regulate metabolism and maintain homeostasis.
Triiodothyronine is responsible for regulating growth and development. When the body has low levels of T3, the thyroid gland produces more T3 hormones. This helps to regulate growth and development in children and adolescents.
The thyroid gland is a vital organ that plays a crucial role in maintaining homeostasis in the body
