Thyroid Notch Inferior

The thyroid glands are paired thyroid glands. They are clearly visible from the outside, they lie near the trachea. A healthy thyroid gland is usually symmetrical. Its thickened ends are directed in both directions, merging with the surrounding tissues. On the outside, the glands are covered with a dense connective capsule, and on the surface

The inferior thyroid notch is a small gap between the thyroid gland and the cricoid ligament, which is also located above.

The thyroid gland belongs to the parathyroid forms in most cases and is connected directly to the gland through the so-called thyroid duct (cricoid ligament), and is also covered on the anterior surface with a dense fibrous capsule (thyroid capsule).

The upper part of the thyroid gland is located in the cavity of the larynx, here it connects with the midline of the posterior part of the organ. However, the thyroid tissue continues beyond the midline (lateral to the jugular fossa) and forms a convexity of the neck, called the lamina of the thyroid cartilage. The posterior surface of this elevation is adjacent to the arytenoid cartilages, located on its side, and its anterior sections face the epiglottis. Above, it articulates with the cricoid rings of cartilage below and behind. Directly in this place is the thyroid (thyreoideus) notch, also called the inferior. It limits the thyroid protrusion formed by the upper part of the gland. At the back, this notch is covered by the cricoid-thyroid membrane. Along the edges of the notch, in its anterior sections, the thyroid gland just passes into the vocal apparatus. This place is called the frenulum (processus vocalis). It is separated from the posterior end of the tongue and is its lower continuation. In this area you can often feel thin threads of hyaline salivary glands. If you look at the lumen of the larynx, the convex thyroid surface will flow around the cricoid cartilage from the outside and in front, and this expanded fragment of the gland is called the thyroid-cricoid muscle.
