Thyroid Gland: T3, T4 (Thyroid Hormones) and Thyroid Problems, Animation

Understanding the Thyroid Gland

1. Location and Function

   • The thyroid gland is a small, butterfly-shaped organ located at the base of the neck.
   • Despite its size, it plays a crucial role in ensuring that all the cells in the body function correctly.

2. Roles of the Thyroid Gland

   • Influences heartbeat and maintains a steady pulse.
   • Regulates body temperature.
   • Affects energy levels.
   • Shapes thoughts and feelings.
   • Plays a role in digestion.

3. Hormones Produced

   • The thyroid produces hormones that travel throughout the body:
     • T3 (Triiodothyronine)
     • T4 (Thyroxine)

4. Regulation of Hormone Production

   • Hormone production is regulated by the brain:
     • Pituitary Gland: Releases Thyroid Stimulating Hormone (TSH) to signal the thyroid.
     • Hypothalamus: Produces TRH to control TSH, maintaining a balanced hormone system.

5. Impact on Health

   • Imbalances in thyroid hormone levels can cause symptoms that are often overlooked.
   • Millions suffer from thyroid issues unknowingly.
