The hyoid branch is the part of the skeleton on which the muscles of the neck and larynx are attached. The isthmus between the mental and hyoid branches of the spinous bone passes into the hyoid bone, which connects to the 7th cervical vertebra using the atlantoaxial joint. The atlantoaxial joint has one axis of rotation, as well as two heads of the occipital bone and a saddle joint, which are connected by the serratus processes. The hyoid bones are attached to the hyoid branch of the spinous and sphenoid bones. The anterior part of the hyoid bones is divided into three parts: the body, the small and large horns, from here they are attached by a transverse joint with the bones: the body to the upper jaw, the small horn with the gothic process - with the body of the sphenoid, the large horn - to the sternum and sternum. The lower ends of the hyoid bones form an arched shape, in the neck muscles, covering the entrance to the oral cavity. The narrow mylohyoid ligament is attached to the lower surface of the hyoid bone. Muscles. Language consists of the brain. The tongue contains 5 muscle parts: back, sides, body and tip. The hyoid tendon is one end: the lateral section is the second, the anterior is the third, the body is the fourth, the body of the tongue muscle is the fifth. The lower edge of the tongue consists of a belly, which transmits movements of the middle third of the tongue to the common hypoglossal canal, where the hypoglossal nerve is located. The lingual muscle of the mandible is attached to the hyoid bones above the hyoid line. The transverse lingual muscles are divided into longitudinal parts (anterior, middle and posterior), which are attached
