Chapter 16, Problem 9c
Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
Thyroid hormones are produced by follicle cells.
Verified step by step guidance1
Step 1: Understand the anatomy of the thyroid gland. The thyroid gland contains structures called follicles, which are spherical units surrounded by follicle cells. These follicle cells play a key role in hormone production.
Step 2: Recall the function of follicle cells. Follicle cells are responsible for synthesizing and secreting thyroid hormones, specifically thyroxine (T4) and triiodothyronine (T3). These hormones are stored in the colloid within the follicles before being released into the bloodstream.
Step 3: Evaluate the statement provided. The statement 'Thyroid hormones are produced by follicle cells' is accurate based on the physiological role of follicle cells in the thyroid gland.
Step 4: Confirm the truth of the statement. Since follicle cells are indeed responsible for producing thyroid hormones, the statement is true and does not require correction.
Step 5: Summarize the reasoning. The statement is true because follicle cells synthesize thyroid hormones, which are essential for regulating metabolism, growth, and development.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Thyroid Hormones
Thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3), are crucial for regulating metabolism, growth, and development in the body. They influence various physiological processes, including heart rate, body temperature, and energy levels. Understanding their role is essential for evaluating statements about thyroid function.

Review of Major Hormones
Follicle Cells
Follicle cells, also known as thyrocytes, are specialized epithelial cells in the thyroid gland responsible for synthesizing and secreting thyroid hormones. They surround the thyroid follicles, where the hormones are produced from iodine and the amino acid tyrosine. Recognizing the function of these cells is vital for understanding the production of thyroid hormones.

Thyroid Gland Structure
The thyroid gland is an endocrine organ located in the neck, composed of follicles filled with colloid, where thyroid hormones are stored. The gland's structure includes follicle cells and parafollicular cells, which produce calcitonin. A clear understanding of the gland's anatomy helps clarify the roles of different cell types in hormone production.
