part of part of in lateral side of lobe of thyroid gland Wikipedia:Lobes_of_thyroid_gland SCTID:245537001 The lobes of the thyroid gland are conical in shape, the apex of each being directed upward and lateralward as far as the junction of the middle with the lower third of the thyroid cartilage; the base looks downward, and is on a level with the fifth or sixth tracheal ring. Each lobe is about 5 cm. long; its greatest width is about 3 cm. , and its thickness about 2 cm. The lateral or superficial surface is convex, and covered by the skin, the superficial and deep fasciæ, the Sternocleidomastoideus, the superior belly of the Omohyoideus, the Sternohyoideus and Sternothyreoideus, and beneath the last muscle by the pretracheal layer of the deep fascia, which forms a capsule for the gland. The deep or medial surface is moulded over the underlying structures, viz. , the thyroid and cricoid cartilages, the trachea, the Constrictor pharyngis inferior and posterior part of the Cricothyreoideus, the esophagus (particularly on the left side of the neck), the superior and inferior thyroid arteries, and the recurrent nerves. The anterior border is thin, and inclines obliquely from above downward toward the middle line of the neck, while the posterior border is thick and overlaps the common carotid artery, and, as a rule, the parathyroids lobus (glandula thyroidea) thyroid gland lobe A lobe of tissue that is part of a thyroid gland. thyroid lobe FMA:13367 NCIT:C33784 VHOG:0000732 EHDAA2:0002032 UBERON:0001118 MA:0000131 EMAPA:18196 thyroid gland anatomical lobe lateral structure
