The Thyroid Gland01:23

The Thyroid Gland

6.9K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Functions of Thyroid Hormones

5.1K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Synthesis and Regulation of Thyroid Hormones

7.4K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Co-activators and Co-repressors

8.4K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

Area of Science:

  • Endocrinology
  • Radiology
  • Oncology

Background:

  • Nodular thyroid disease is highly prevalent, with most nodules being benign.
  • Sonography is crucial for differentiating benign from potentially malignant thyroid nodules.
  • Distinguishing nodular thyroid disease from diffuse thyroid conditions is essential.

Purpose of the Study:

  • To highlight the role of sonography in evaluating nodular thyroid disease.
  • To explain the application of the American College of Radiology's Thyroid Imaging Reporting and Data System (TI-RADS) for risk stratification.
  • To emphasize the importance of recognizing sonographic features for appropriate patient management.

Main Methods:

  • Utilizing sonographic imaging to assess thyroid nodule characteristics.
  • Applying the Thyroid Imaging Reporting and Data System (TI-RADS) for risk stratification based on sonographic appearance and nodule size.
  • Comparing sonographic findings with clinical management decisions (fine-needle aspiration or surveillance).

Main Results:

  • Sonography effectively identifies features indicative of malignancy versus benignity in thyroid nodules.
  • The TI-RADS system provides a standardized approach to risk-stratify nodules.
  • Sonographic assessment guides decisions for further diagnostic procedures or monitoring.

Conclusions:

  • Sonography is a key tool in managing nodular thyroid disease.
  • The TI-RADS classification aids in determining the need for fine-needle aspiration or surveillance.
  • Understanding sonographic patterns is vital for accurate diagnosis and patient care.
