Chapter 7 - The skeleton (part a) provides knowledge of the skull. After completing this unit, you should be able to: Name, describe, and identify the skull bones. Identify their important markings; compare and contrast the major functions of the cranium and the facial skeleton. | 7 The Skeleton: Part A The Axial Skeleton Consists of 80 bones Three major regions Skull Vertebral column Thoracic cage Figure Skull Thoracic cage (ribs and sternum) (a) Anterior view Facial bones Cranium Sacrum Vertebral column Clavicle Scapula Sternum Rib Humerus Vertebra Radius Ulna Carpals Phalanges Metacarpals Femur Patella Tibia Fibula Tarsals Metatarsals Phalanges The Skull Two sets of bones Cranial bones Enclose the brain in the cranial cavity Cranial vault (calvaria) Cranial base: anterior, middle, and posterior cranial fossae Provide sites of attachment for head and neck muscles The Skull Facial bones Framework of face Cavities for special sense organs for sight, taste, and smell Openings for air and food passage Sties of attachment for teeth and muscles of facial expression Figure Bones of cranium (cranial vault) Lambdoid suture Facial bones Squamous suture (a) Cranial and facial divisions of the skull Coronal suture Figure Anterior cranial fossa Middle cranial fossa Posterior cranial fossa (b) Superior view of the cranial fossae Cranial Bones Frontal bone Parietal bones (2) Occipital bone Temporal bones (2) Sphenoid bone Ethmoid bone Frontal Bone Anterior portion of cranium Most of anterior cranial fossa Superior wall of orbits Contains air-filled frontal sinus Figure Parietal bone Squamous part of frontal bone Nasal bone Sphenoid bone (greater wing) Temporal bone Ethmoid bone Lacrimal bone Zygomatic bone Maxilla Mandible Infraorbital foramen Mental foramen (a) Anterior view Mandibular symphysis Frontal bone Glabella Frontonasal suture Supraorbital foramen (notch) Supraorbital margin Superior orbital fissure Inferior orbital fissure Middle nasal concha Inferior nasal concha Vomer Optic canal Perpendicular plate Ethmoid bone Parietal Bones and Major Associated Sutures Superior and lateral aspects of cranial vault Four sutures mark the articulations of parietal bones with frontal, occipital, and temporal bones: Coronal suture—between . | 7 The Skeleton: Part A The Axial Skeleton Consists of 80 bones Three major regions Skull Vertebral column Thoracic cage Figure Skull Thoracic cage (ribs and sternum) (a) Anterior view Facial bones Cranium Sacrum Vertebral column Clavicle Scapula Sternum Rib Humerus Vertebra Radius Ulna Carpals Phalanges Metacarpals Femur Patella Tibia Fibula Tarsals Metatarsals Phalanges The Skull Two sets of bones Cranial bones Enclose the brain in the cranial cavity Cranial vault (calvaria) Cranial base: anterior, middle, and posterior cranial fossae Provide sites of attachment for head and neck muscles The Skull Facial bones Framework of face Cavities for special sense organs for sight, taste, and smell Openings for air and food passage Sties of attachment for teeth and muscles of facial expression Figure Bones of cranium (cranial vault) Lambdoid suture Facial bones Squamous suture (a) Cranial and facial divisions of the skull Coronal suture Figure Anterior cranial fossa Middle .
