“Visualizing the Synthesis of Thyroid Hormones” is an animated video presentation designed to help students visualize the steps in thyroid hormone synthesis. The material describes the complex process of thyroid hormone synthesis from the step of iodide trapping to the attachment of hormone on the peripheral receptors. Topics covered include: 1) iodide trapping, 2) oxidation of iodide, 3) synthesis of thyroglobulin 4) iodination of tyrosine, 5) conjugation of T1 and T2, 6) endocytosis and digestion of colloid, 7) secretion of thyroid hormones, 8) conversion of T4 to T3 at target tissues, and 9) binding of T3 to nuclear receptors. The presentation is short, lasting 7 minutes and 43 seconds. The target audience is college or graduate students.
Type of Material:
This material is provided as an animated presentation.
This presentation could be used in the “flipped classroom” method of teaching where students can preview this presentation prior to coming to class. This presentation could be used during a lecture or could be used as a supplemental resource for students.
Technical requirements include Adobe Flash Player. At the time of this review, the material was best viewed in Mozilla Firefox 19.0+, Internet Explorer 9.0+, and Google Chrome.
Identify Major Learning Goals:
Students will be able to describe the steps involved in the synthesis of thyroid hormones T3 and T4. Users will also be able to describe a thyroid follicle and explain the step by step process of thyroid hormone production.
Target Student Population:
This material can be used at all levels of undergraduate and graduate education.
Prerequisite Knowledge or Skills:
Although no prerequisites are mentioned for this material, better understanding would be achieved with some college level understanding of human physiology.
