Bones Flashcards
formed by two sets of bones.
SKULL
composed of eight large flat bones.
Cranium
forms the forehead, the bony projections under the eyebrows, and the superior part of each eye’s orbit.
Frontal Bone
form most of the superior and lateral walls of the cranium.
Parietal Bones
lie inferior to the parietal bones and join them at the squamous sutures.
Temporal Bones
the most posterior bone of the cranium.
Occipital Bone
spans the width of the skull and forms part of the floor of the cranial cavity.
Sphenoid Bone
very irregularly shaped and lies anterior to the sphenoid It forms the roof of the nasal cavity and part of the medial walls of the orbits.
Ethmoid Bone
Fourteen bones make up the face. Twelve are paired; only the mandible and vomer are single.
Facial Bones
The two maxillae or maxillary bones,fuse to form the upper jaw.
Maxillae
lie posterior to the palatine processes of the maxillae.
Palatine Bones
commonly referred to as the cheekbones.
Zygomatic Bones
are fingernail-sized bones forming part of the medialwall of each orbit.
Lacrimal Bones
The small rectangular bones forming the bridge of the nose are the nasal bones.
Nasal Bones
The single bone in the median line of the nasal cavity is the vomer.
Vomer Bone
