superior part of orbits and anterior cranial fossa; contains sinuses Term Supraorbital foramen (notch) Definition allows the supraorbital arteries and nerves to pass Term Parietal Definition forms most of the superior and lateral aspects of skull Term Occipital Definition forms posterior aspect and most of the base of the skull Term Foramen magnum Definition allows the spinal cord to issue from the brain stem to enter the vertebral canal Term Hypoglossal canal Definition allows passage of the hypoglossal nerve Term Occipital Condyle Definition articulates with the atlas (first vertebrae) Term External occipital protuberance and nuchal lines Definition sites of muscle attachment Term external occipital crest Definition attachment site of ligementum nuchae Term Temporal Definition forms inferolateral aspects of the skill and contributes to the middle cranial fossa; has squamous, mastoid, tympanic and petrous regions Term zygomatic process Definition helps to form the zygomatic arch, which forms the prominence of the cheek Term mandibular fossa Definition articular point of the mandibular condyle Term external acoustic meatus Definition canal leading from the external ear to the eardrum Term styloid process Definition attachment site for hyoid bone and several neck muscles Term mastoid process Definition attachment site for several neck and tongue muscles Term jugular foramen Definition allows passage of the internal jugular vein and cranial nerves Term stylomastoid foramen Definition allows cranial nerve (facial nerve) to pass Term internal acoustic meatus Definition allows passage of cranial nerves Term carotid canal Definition allows passage of the internal carotid artery Term sphenoid Definition keystone of the cranium; contributes to the middle cranial fossa and orbits; main parts are the body, greater wings, lesser wings, and pterygoid processes Term sella turcia Definition hypophyseal fossa portion is the seat of the pituitary gland Term optic canal Definition allows passage of cranial nerve and the opthalmic arteries Term superior orbital fissure Definition allows passage of cranial nerves and ophthalmic vein Term foramen rotundum Definition allows passage of the maxillary division of cranial nerve Term foramen ovale Definition allows massage of the mandibular division of cranial nerve Term foramen spinosum Definition allows passage of the middle meningeal artery Term ethmoid Definition helps to form the anterior cranial fossa; forms part of the nasal septum and lateral walls and roof of the nasal cavity; contributes to the medial wall of the orbit Term auditory ossicles Definition found in middle ear cavity; involved in sound transmission Term crista galli Definition attachment point for the falx cerebri, a dural membrane Term cribriform plate Definition allows passage of nerve filaments of the olfactory nerves Term superior and middle nasal conchae Definition forms part of lateral walls of nasal cavity; increase turbulence of air flow Term Mandible Definition lower jaw Term Maxilla Definition keystone bones of the face; form the upper jaw and parts of the hard palate, orbits and nasal cavity walls Term coronoid process Definition insertion point for the temporalis muscle Term mandibular condyle Definition articulates with the temporal bones in freely movable joints of the jaw Term mandibular symphysis Definition medial fusion point of the mandibular bones Term alveoli Definition sockets for the teeth Term mandibular foramen Definition permits the inferior aveolar nerves to pass Term palatine process Definition forms the anterior hard palate; processes meet in medial palatine suture Term frontal process Definition forms part of lateral aspect of bridge of nose Term incisive fossa Definition permits blood vessels and nerves to pass through hard palate Term inferior orbital fissure Definition permits maxillary branch of cranial nerve, the zygomatic nerve, and blood vessels to pass Term infraorbital foramen Definition allows passage of infraorbital nerve to skin of face Term zygomatic Definition forms the cheek and part of the orbit Term nasal Definition constructs the bridge of the nose Term lacrimal Definition forms part of the medial orbit wall Term lacrimal fossa Definition houses the lacrimal sac, which helps to drain tears into the nasal cavity Term palatine Definition forms the posterior part of the hard palate and a small part of nasal cavity and orbit wall Term vomer Definition part of the nasal septum Term inferior nasal concha Definition forms part of the lateral wall of the nasal cavity Term Paranasal Sinuses Picture Definition Term Hyoid Bone Picture Definition Term Vertebral column Picture Definition Term Structure of Vertebra Picture Definition Term Atlas Picture Definition Term Axis Picture Definition Term Cervical vertebra picture Definition Term Thoracic verebrae Picture Definition Term Lumbar Vertebrae Picture Definition Term Sacrum Picture Definition Term Fontanels Definition hyaline cartilage, soft area at birth, new room for brain expansion Term Sutures Definition where two bones come together Term Foramen Definition openings for passage of soft tissue Term Sinuses Definition frontal, ethmoid, sphenoid, maxillary. air pockets Term Vertebral Column Function Definition S shaped spring with 26 bones connected by intervertebral disks. Protects spinal cord, supports neck and trunk, flexibility Term Curvatures of Vertebral Column Definition Cervical (concave), Thoracic (convex), Lumbar (concave), Sacral (Convex) Term Invertebral Disk Definition made of fibrocartilage between vertebraes. Composed of nucleus pulposus (gel) and annulus fibrous (dense regular connective tissue, cartilage, mostly collagen) Allows for flexibilityw. slipped disk Term Cause of slipped disk Definition annulus weakens, pulpus comes out, slipped disk Term Typical Vertebra Definition Body (support), arch (creates arch over body), processes (sticks out and skeletal muscle attaches) Term Cervical Vertebra Definition 7, includes atlas and axis. Concave Term Thoracic vertebra Definition 12. Convex Term Lumbar Vertebra Definition 5. Concave Term Sacrum Definition 1. 5 bones fused together. Convex Term Coccyx Definition 1 bone Term Number of ribs Definition 12 pairs
