(186 cards)
Appendicular skeleton
The limbs, including the bones of the shoulders, upper extremities, hip, and lower extremities.
Axial Skeleton
Central bony structure of the body. It consists of the bones of the head, associated bones of the head and neck, the chest, and the spine.
Bones
The framework on which the body is built. The 206 individual pieces of the skeleton. Bone is known as osseous tissue. Bony and o steal are also adjectives for bone.
Musculoskeletal system
The combined systems of the muscles and bones. The bones provide structural support for the body and work in conjunction with the muscles to maintain body posture and produce movement.
Skeletal system
Body system that consists of all the bones, cartilage, ligaments, and joints in the body. It provides structural support and protection for soft tissues and internal organs.
It is a storage site for calcium and phosphorus. the red bone marrow is the site of blood cell production.
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. The superior and medial conchae of the ethmoid bone are bony projections within the nasal cavity. The ethmoid bone contains many small, hollow air spaces of the ethmoid sinus.
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. The spinal cord goes through it to join with the brain.
Frontal Bone
Bone that forms the forehead and top of the cranium and ends at the coronal suture. It contains the hollow cavities of the frontal sinuses.
Occipital bone
Bone that forms the posterior base of the cranium. It contains the large opening of the foramen magnum.
Parietal bones
Bones that form the superior sides and posterior part of the cranium. They join at the sagittal suture.
Skull
Bony structure of the head that includes the cranium and facial 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.
It contains the hollow cavities of the sphenoid sinuses. A bony cup in the sphenoid bone holds the pituitary gland.
Suture
Type of join where one cranial bone meets another. It is an immovable joint that contains no cartilage.
Temporal bones
Bones that form the inferior sides of the cranium. Each temporal bone has a bony opening for the external ear canal and contains the hollow cavity of the middle ear.
Bony landmarks include the mastoid process behind the ear and the pointed style I’d process, a site of attachment for ligaments to the hyoid bone.
Inferior nasal conchae
Facial bones that project inwardly from the side of the nasal cavity.
Lacrimal bones
Facial bones within the eye socket. They are small, flat bones near the lacrimal glands (of the eyes that produce tears)
Mandible
Facial bone that is the lower jaw bone and contains the roots of the lower teeth. It is the only movable bone in the skull. Together with the temporal bone, the movable mandible forms the temporomandibular joint located just anterior to the ear.
Maxilla
Facial bone that is the upper jaw bone. It contains the roots of the upper teeth and the hollow cavities of the maxillary sinuses. The maxilla consists of two fused maxillary bones.
Nasal bones
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.
