Arch
Arch
An Arch in medical terminology refers to a natural curvature structure in the body. It can be found in various parts of the human anatomy, such as the foot, the palate, and the aorta.
Foot Arch
The Foot Arch is a curved structure in the foot, composed of three parts: the medial, lateral, and transverse arches. These arches are formed by the tarsal and metatarsal bones and are strengthened by ligaments and tendons. They play a crucial role in supporting the body's weight and in providing balance and stability during movement.
Palatal Arch
The Palatal Arch is a curved structure in the roof of the mouth. It is divided into two parts: the anterior hard palate and the posterior soft palate. The hard palate is formed by the palatine processes of the maxillary bones and the horizontal plates of the palatine bones. The soft palate is a muscular fold that extends from the posterior edge of the hard palate and separates the oral cavity from the nasal cavity.
Aortic Arch
The Aortic Arch is a curved portion of the main artery that carries blood from the heart to the rest of the body. It begins at the level of the second thoracic vertebra and ends at the level of the fourth thoracic vertebra. The aortic arch gives rise to three major branches that supply blood to the head, neck, and upper limbs.
