Synthesis of the amino acid–derived T 3 and T 4 hormones requires iodine. It lies behind the sternohyoid and sternothyroid muscles, wrapping around the cricoid cartilage and superior tracheal rings. The thyroid gland is located in the anterior neck, spanning between the C5 and T1 vertebrae.It is an endocrine gland, divided into two lobes which are connected by an isthmus.It is said to have a butterfly shape. The thyroid hormones triiodothyronine (T 3) and thyroxine (T 4) are produced and secreted by the thyroid gland in response to thyroid-stimulating hormone (TSH) from the anterior pituitary.

Thyroid Gland – Introduction The thyroid gland contains two main types of cells: follicular cells that produce thyroxin and C cells that produce calcitonin.

Thyroid hormones are able to diffuse freely across cell membranes. Amines - derivatives of tyrosine (amino acid). Thyroid hormone is produced in response to elevated pituitary TSH levels. Spell. A thin fibrous capsule with blood vessels, lymphatics, and nerves, most prominent at the poles, encloses the thyroid. STUDY.

The effects of the hormones it produces can be seen throughout all systems in the body. The thyroid gland has lobular organization. Steroids - synthesized from cholesterol. The thyroid gland is located dorsolateral to the trachea, close to the larynx. The thyroid regulates basal metabolic rate by secretion of thyroid hormones stored in thyroid follicles.

Thyroid gland is located in neck, anterior to trachea.

PLAY. The thyroid gland is an endocrine organ located in the neck that participates in a myriad of systemic processes. Digital Histology. Near the thyroid gland and embedded in the same connective tissue capsule is the parathyroid gland. The numerous thyroid follicles form the secretory units of the thyroid gland. An other hormone produced by the thyroid gland, calcitonin, is produced in response to elevated blood calcium levels. Flashcards. It consists of two lobe-one on each side of junction between laryngotrachea.
