Thyroid gland – Anatomy and Function Diagram

This thyroid gland diagram provides a clear overview of neck anatomy and endocrine physiology. Users can study the anatomy of thyroid gland by identifying the thyroid cartilage and the right and left lobes connected by the isthmus. The microscopic view explains the function of thyroid gland through the visualization of follicles of thyroid gland and parafollicular cells. Each follicular cell surrounds the thyroid gland colloid to facilitate hormone synthesis and the release of T3 and T4 into capillary blood vessels. These hormones impact target organs like the brain, heart, and liver. This visual is a vital tool for understanding endocrine health. Our hand-illustrated style utilizes clean lines and a soft color palette that offers superior clarity over a standard labeled diagram.
