HLSC 2F95 Lecture Notes - Lecture 2: Inferior Nasal Concha, Inferior Orbital Fissure, Superior Orbital Fissure
Document Summary
The axial skeleton: composed of the bones along the central axis of the body, skull bones, auditory ossicles, hyoid, vertebral column, thoracic cage, face. Bones of the skull: maxilla, palatine bones, nasal bones, inferior nasal conchae, zygomatic bones, vomer, mandible, occipital bone, parietal bones, frontal bones, temporal bones, sphenoid, ethmoid, associated bones, auditory ossicles, hyoid bone, cranium. Ethmoid bone: most deep of the skull bones, lies between the sphenoid and nasal bones. Palatine bone: two bone plates that form portions of the hard palate, the posterolateral walls of the nasal cavity, and a small part of the orbits. Mandible: the mandible (lower jawbone) is the largest, strongest bone of the face. Sinuses: here for circulation and keep the head light. The hyoid bone: does not articulate with any other bone, it is suspended inferior to the skull, it is important to anchor muscles around the tongue.
