Follicles are a structural feature of what gland?
thyroid gland!
What endocrine gland stores its product in follicles?
Thyroid
What type of tissue lines the follicles of the thyroid glands?
T3 and T4
Thyroid follicles are filled with a substance called colloid what is the purpose of colloid?
It's gelatinous-like substance that holds the hormonal secretions of the thyroid gland.
What has the author Pierre Cau written?
Pierre Cau has written: 'Morphogenesis of thyroid follicles in vitro' -- subject(s): Cultures and culture media, Morphogenesis, Thyroid gland
Where is iodine stored in humans body?
thyroid gland
Where are humans eggs stored?
In follicles found in a female's ovaries.
How are the thyroid and parathyroid glands linked anatomically?
Thyroid glands are located in the neck, in close approximation to the first part of the trachea. In humans, the thyroid gland has a "butterfly" shape, with two lateral lobes that are connected by a narrow section called the isthmus. Most animals, however, have two separate glands on either side of the trachea. Thyroid glands are brownish-red in color.Close examination of a thyroid gland will reveal one or more small, light-colored nodules on or protruding from its surface - these are parathyroid glands (meaning "beside the thyroid").The microscopic structure of the thyroid is quite distinctive. Thyroid epithelial cells - the cells responsible for synthesis of thyroid hormones - are arranged in spheres called thyroid follicles. Follicles are filled with colloid, a proteinaceous depot of thyroid hormone precursor.In addition to thyroid epithelial cells, the thyroid gland houses one other important endocrine cell. Nestled in spaces between thyroid follicles are parafollicular or C cells, which secrete the hormone calcitonin.The structure of a parathyroid gland is distinctly different from a thyroid gland. The cells that synthesize and secrete parathyroid hormone are arranged in rather dense cords or nests around abundant capillaries.
Where iodine is stored?
Iodine is mostly stored in the thyroid, but smaller amounts are in the muscles and bones. Indirectly, iodine has a major effect on a lot of systems in the body through the thyroid gland.
What Hormone is produced or stored by the parafollicular cells of the thyroid?
Calcitonin
How are thyroid hormones stored?
They are stored in the colloid as the protein thyroglobulin. Thyroglobulin is essentially T3 and T4 linked together into a protein.
What is atypical follicular cells of thyroid?
Thyroid follicles are the tiny spheres that the thyroid gland is made of. The thyroid is a butterfly-shaped gland that sits around the base of the neck, near the Adam's apple. It produces hormones that regulate the metabolism.
