Muscles of Swallowing Muscles of Swallowing The anterior portion of the neck is divided into the suprahyoid and infrahyoid muscle groups Muscles of Swallowing The anterior portion of the neck is divided into the suprahyoid and infrahyoid muscle groups. 1. Muscles of the Thoracic Wall. a. . intercostals (external/internal). * L: between ribs. * A: elevate/depress rib cage (breathing). Origin:. . Inferior border of rib above. . Vertebral Column (Spine). Extends from the skull, which it supports, to the pelvis, where it transmits the weight of the body to the lower limbs. The spine is formed from 26 irregular bones connected and reinforced by ligaments in such a way that a flexible curved structure results. Together with ribs and sternum provide about two-fifths (40%) of the height of the body. Composed of 33 (26) different bones. Encloses and protects the spinal cord. Supports the head. Lower vertebrae supports the weight of the entire upper body. Over 600 in the human body. Allow the skeleton to move. To cause movement, both ends of each muscle must be attached to bone. Origin or proximal attachment – the attachment closer to the center of the body. Vertebral Column. 26 bones. : . Vertebrae (24). Sacrum. Coccyx (. tailbone).
