Thyroid hormone metabolism a comparative evaluation essay.
The thyroid gland is abundant with blood vessels and it secretes thyroid hormone (Kumar 22). Thyroid hormone influences many different internal body functions such as, metabolism, growth, development, turning food into energy, and increases body temperature. Thyroid hormone is very important for brain development and normal growth during.
Hyperthyroidism is the condition that occurs due to excessive production of thyroid hormones by the thyroid gland. Thyrotoxicosis is the condition that occurs due to excessive thyroid hormone of any cause and therefore includes hyperthyroidism. Some, however, use the terms interchangeably. Signs and symptoms vary between people and may include irritability, muscle weakness, sleeping problems.

Mechanism of Action and Physiologic Effects of Thyroid Hormones Thyroid Hormone Receptors and Mechanism of Action. Receptors for thyroid hormones are intracellular DNA-binding proteins that function as hormone-responsive transcription factors, very similar conceptually to the receptors for steroid hormones. Thyroid hormones enter cells through membrane transporter proteins.

The relation between thyroid function and depression has long been recognized. Patients with thyroid disorders are more prone to develop depressive symptoms and conversely depression may be accompanied by various subtle thyroid abnormalities. Traditionally, the most commonly documented abnormalities are elevated T4 levels, low T3, elevated rT3, a blunted TSH response to TRH, positive.
