THYROID - stock photo

Model of the intern anatomy of the neck of an adult human body, in three-quarter view. In the left half of the head are shown the bones of the face. Behind the Adam's apple, the larynx (in light blue) is composed of several cartilages, but only the thyroid cartilage is seen here. It is linked by ligaments (in white) to the cricoid cartilage, masked by the thyroid gland (by the cricothyroid ligament) and to the hyoid bone, at the base of the skull (by the thyrohyoid membrane). The larynx continues with the trachea, whose cartilaginous rings are illustrated in light blue. The thyroid gland (in light orange) covers the trachea. It is irrigated by the superior thyroid arteries (in red), coming from the common carotid arteries (in red, steming from the aortic arch, running alongside the larynx and going oxygenate the head structures). The inferior thyroid veins (in royal blue) emerge from the thyroid gland and lead to the internal jugular vein. The right and left internal jugular veins (in royal blue) begin at the base of the skull, go down on both sides of the throat to reach the clavicles, where they join up with the subclavian veins (coming from the upper limbs) to form the brachiocephalic trunk. The latter flows into the superior vena cava, which spills into the heart. The scalene muscles (in carmine), located on the sides of the neck, allow to incline the head and the cricothyroid muscle (in carmine), situated between the thyroid cartilage and the thyroid gland, stretchs the vocal cords.
