Document Summary
An introduction to the axial skeleton: structures of bones, articulations, contacts with other bones, landmarks (bone markings; marks, areas of muscle and ligament attachment, foramina, openings for nerves and blood vessels. A depression on the medial surface for submandibular salivary gland. Mylohyoid line for insertion of the mylohyoid muscle (floor of mouth) Ramus ascending from the mandibular angle on either side. Condylar process articulates with temporal bone at temporomandibular joint. Coronoid process insertion point for temporalis muscle (closes the jaw) Mandibular notch separates condylar and coronoid processes: foramina: Mental foramina for sensory serves of lips and chin. Intervertebral foramina: gaps between pedicles of adjacent vertebrae, for nerve connections to spinal cord, vertebral canal, formed by vertebral foramina, encloses the spinal cord. Inferior articular processes: face down and out, transverse processes, slender, project dorsolaterally, spinous processes, short, heavy, for attachment of lower back muscles, sacral (s, the sacrum. Merge with cartilage before reaching the sternum: floating or vertebral ribs (11-
