The thyroid, or thyroid gland, is an endocrine gland in the neck consisting of two connected lobes. The lower two thirds of the lobes are connected by a thin band of tissue called the thyroid isthmus. The thyroid is located at the front of the neck, below the Adam's apple.

The parathyroid glands weigh roughly 50 mg and have a yellow-tan color. The glands are generally adjacent to the thyroid gland and lie flat against it. They also

Increased levels are associated with increased speed of thought generation but decreased focus. The thyroid gland begins development as a proliferation of endodermal cells between the cupola and tuberculum impar of the primitive tongue (the site of the future foramen cecum). This proliferation of cells bifurcates and descends into the neck as a two-lobed diverticulum. The thyroid is the body's first endocrine gland to develop, with development beginning around the third week of gestation. The thyroid arises from the pharyngeal pouches, which are composed of endoderm.

Now have a look at this eMicroscope of a higher power image of the thyroid gland.. Can you identify the thyroid follicles, the simple cuboidal epithelium that lines the follicles, colloid, and can you find a 'clear cell'.

Parafollicular cells are pale-staining cells found in small number in the thyroid and are typically situated basally in the epithelium, without direct contact with the follicular lumen.They are always situated within the basement membrane, which surrounds the entire follicle.. Development. Parafollicular cells are derived from pharyngeal endoderm. [1, 2] The embryology knowledge allows us to understand the anatomical variants. [3] In 90% of cases, ectopic tissue is a lingual thyroid; its incidence range between 1 in 3000 and 1 in Ninja Nerds,Join us in this video where we give a brief description of the thyroid gland and an overview of this important endocrine organ. ***PLEASE SUPPORT Almen embryologi.
