Chapter 7 Flashcards
Appendicular skeleton
the limbs, including the bones of the shoulders, upper extremities, hip, and lower extremities
Axial skeleton
central bony structure of the body
consists of the bones of the head, associated bones of the head and neck, the chest and the spine
Bones
framework of which the body is built
Musculoskeletal system
the combined systems of the muscles and bones
Skeletal system
body system that consists of all of the bones, cartilage, ligaments, and joints in the body
Skeleton
bony framework of the body that consists of 206 bones
Coronal suture
immovable joint on top of the cranium, extending from one side to the other, where the frontal bone and the parietal bones meet
Cranium
dome-like bone at the top of the skull that contains the cranial cavity with the brain and other structures
Ethmoid bone
bone that forms the posterior nasal septum and the medial walls of the eye sockets
Fontanel
“soft spot” on a baby’s head where the cranial sutures are still open and there is only fibrous connective tissue
Foramen magnum
large hole in the occipital bone
spinal cord goes through it to join the brain
Frontal bone
bone that forms the forehead and top of the cranium and ends at the coronal suture
Occipital bone
bone that forms the posterior base of the cranium
Parietal bones
bones that form the superior and posterior part of the cranium
Sagittal suture
immovable joint from the top center to the back of the cranium between the two parietal bones
Sphenoid bone
large, irregularly shaped bone that forms the central base and sides of the cranium and the posterior walls of the eye sockets
Skull
bony structure of the head that includes the cranium and facial bones
Suture
type of joint where one cranial bone meets another
Temporal bones
bones that form the inferior sides of the cranium
Inferior nasal conchae
facial bones that project inwardly from the side of the nasal cavity
Lacrimal bones
facial bones within the eye socket
Mandible
facial bone that is the upper jaw bone
Maxilla
facial bone that is the upper jaw bone
consists of two maxillary bones
Nasal bone
facial bones that form the bridge of the nose and the roof of the nasal cavity
Palatine bones
facial bones that are small and flat and join in the midline to form the hard palate in the oral cavity
Vomer
facial bone that is the most inferior part of the nasal septum and continues posteriorly to join the sphenoid bone
Zygoma
facial bone that is a cheekbone and goes to the edge of the eye socket
aka zygomatic bone
Hyoid bone
flat u-shaped bone in the anterior neck
Ossicles
three tiny bones in the middle ear cavity that function in the process of hearing
malleus, incus, stapes
Costal cartilage
firm, but flexible connective tissue that joins the ribs to the sternum at the costochondral joint
Ribs
twelve pairs of bones that form the sides of the rib cage
