Question
Chapter 49.5, Problem 2C
Summary Introduction
To draw: A diagram illustrating how thyroid hormone secretion is regulated.
Introduction: The thyroid gland is a butterfly-shaped endocrine gland and it is enclosed within a connective tissue capsule. The thyroid gland is located near the neck. It contains two lobes, which are connected by an isthmus. There are two hormones secreted by the thyroid gland, namely thyroxine (T4) and triiodothyronine (T3). These hormones help in the normal functioning of the body.

Create a hormone map. A complete map will include the secretion signal for the hormone, the origin of the hormone, and hormone targets, and the physiological outcomes of hormone increases or decreases within the body. Be sure to indicate feedback loops within your map. Please provide an explanation of the steps within your map and explain why this interaction is important physiologically.

- Feedback loops regulate the release of hormones in either a positive or negative loop. Consider this example: The hypothalamus releases thyrotropin releasing hormone (TRH), which stimulates the pituitary to release the TSH (thyroid stimulating hormone). TSH then stimulates thyroid gland to release thyroid hormone. When elevated levels of thyroid hormone are detected by the hypothalamus and pituitary further release of TRH and TSH is suppressed. b.
