(noun)

Examples of triiodothyronine in the following topics:

  • Control of Thyroid Hormone Release

    • The production of thyroxine and triiodothyronine is regulated by thyroid-stimulating hormone (TSH) that is released from the anterior pituitary.
    • The production of thyroxine (T4) and triiodothyronine (T3) is primarily regulated by thyroid-stimulating hormone (TSH) that is released from the anterior pituitary gland.

  • Action of Thyroid Hormones

    • The primary function of the thyroid is to produce the hormones triiodothyronine (T3), thyroxine (T4), and calcitonin.
    • Triiodothyronine (T3) and thyroxine (T4) are enzymes produced by the thyroid gland.

  • Formation, Storage, and Release of Thyroid Hormones

    • The thyroid hormones thyroxine (T4) and triiodothyronine (T3) are produced from thyroid follicular cells within the thyroid gland, a process regulated by the thyroid-stimulating hormone secreted by the anterior pituitary gland.

  • Overview of the Thyroid Gland

    • It participates in these processes by producing thyroid hormones, the principal ones being triiodothyronine (T3) and thyroxine (sometimes referred to as tetraiodothyronine (T4)).

  • Pituitary Gland Disorders

    • Thyroid-stimulating hormone (TSH) deficiency leads to hypothyroidism (lack of production of thyroxine (T4) and triiodothyronine (T3) in the thyroid).

  • Development of the Endocrine System

    • It is involved in the production of the hormones T3 (triiodothyronine) and T4 (thyroxine).

  • Overview of Endocrine Glands

    • It is involved in the production of the hormones T3 (triiodothyronine) and T4 (thyroxine).
