Hyoid Arch

Hyoid arch: anatomical structure and its role in the body

The hyoid arch, also known as the hyoid arch or arcus secundus, is an anatomical structure that is located in the pharynx and is an important part of the respiratory and digestive system.

Anatomy of the hyoid arch

The hyoid arch is a bend of the muscles located in the pharynx. This structure connects the upper part of the thyroid cartilage with the hyoid bone, which is located in the region of the hyoid fossa. The hyoid arch is composed of several muscle fibers, including the superior and inferior hyoid muscles, as well as the vast pharyngeal muscle.

The role of the hyoid arch in the body

The hyoid arch plays an important role in the body, participating in both the process of breathing and digestion. This structure helps keep the larynx and airways open, allowing air to flow freely into the lungs. At the same time, the hyoid arch is also involved in the movement of the tongue and pharynx necessary for proper swallowing of food.

In addition, the hyoid arch is important when performing certain medical procedures. For example, during intubation, where the patient's airway is maintained by inserting a tube into the pharynx, the hyoid arch can be an important support for the tube, providing stability and preventing it from dislodging.

In conclusion, the hyoid arch is an important anatomical structure that plays an important role in the functioning of the respiratory and digestive systems. Its understanding and study are of great importance for medical practice and help ensure optimal functioning of the body.
