30 paź 2023 · The thyroid gland is a bilobular endocrine gland that is found in the neck, anterior and inferior to the larynx. Grossly, the gland appears brownish-red and the left and right lobes are connected by an isthmus. The main purpose of this organ is to produce, store and secrete the iodine-based hormones triiodothyronine (T3) and thyroxine (T4).
Histology Revolution: from inefficient, two-dimensional, and low-resolution techniques to high-throughput, three-dimensional and high-resolution techniques
Thyroid. The thyroid gland is a bilobed endocrine gland. It is unique in that it stores its hormones bound to an extracellular pool of protein (colloid). Stroma Capsule - enclosed by a thin layer of connective tissue. Trabeculae - connective tissue extends inwards from the capsule to partially outline irregular lobes and lobules.
Download scientific diagram | Histological examination (H and E) staining of thyroid glands; (A-G) represented the groups of control, hypo, T4, FZ, GJ, RG, and WZY, respectively.
1 mar 2009 · Purpose of thyroid gland is to produce T4 and T3, which regulate metabolism, increase protein synthesis and increase oxygen consumption in all cells in body; T4 and T3 are also important for growth and development, and maturation of peripheral and central nervous system.
The histological section at 20X magnification using H&E stain shows normal thyroid tissue with normofollicular and macrofollicular changes. The single layer of epithelium surrounding the follicle is made up of a simple cuboidal cells and the lumen is filled with pink staining colloid.
Describe the location and anatomy of the thyroid gland; Discuss the synthesis of triiodothyronine and thyroxine; Explain the role of thyroid hormones in the regulation of basal metabolism; Identify the hormone produced by the parafollicular cells of the thyroid
