- Lateral Shares Are Located At Level -

- Lateral shares are located at level - thyroid and cartilages, and the bottom pole to V - VI rings-. The weight of a thyroid gland at the adult person makes 25 - 30 Additional thyroid gland shares - can settle down from a root of language to an aorta arch (rice 1) Gland is covered by the fourth a neck consisting from thin internal and more powerful external leaves-. Between leaves - pass arterial and venous vessels. From a capsule in gland extend layers, which to gland on segments. Segments consist of the follicles, which wall single-layered cubic . Follicles are filled , consisting of a liquid including ribonuclein, , , iodine, and other enzymes. Thyroid gland blood supply is carried out by four basic arteries two top thyroid (a thyreoidea superior), departing from an external carotid, and the fifth unpaired artery (a thyreoidea ima), departing from arteries is available two bottom thyroid arteries (a thyreoidea inferior) which originate from department arteries Sometimes or from an aorta arch Thyroid arteries pass nearby, and sometimes cross with a returnable nerve It it is necessary to mean during operation as at bandaging of the bottom thyroid artery nerve damage is possible that leads or to a paralysis of vocal chords According to arteries there are the pair veins which branches form powerful textures.
