• what are the paired cranial bones? temporal, parietal
• What is the temporomandibular joint? Moveable joint in the skull that consists of the mandible and the temporal bone
• Clef palate is created by the incomplete closure of the ... palatine process
• How is the hard palate formed? the hard palate is formed by the palatine process of the maxilla and the palatine bone
• What forms the nasal septum? ethmoid and vomer
• The palatine bone forms _ of the hard palate and forms the _ wall of _ cavity 1/4, lateral, nasal
• What forms the superior and middle conchae? ethmoid bone
• The inferior nasal concha forms? The inferior part of the nasal cavity
• What is foramen magnum? large hole in base of skull that the brainstem and spinal cord leaves through
• what is condoyles? bumps articulating with cervical vertebra 1
• What is the joint present berween the occipital bone and cervical vertebra one? synovial joint
• What are some of the characteristics for the temporal bone? Creates the external and internal auditory meatus. articulates with condylar process of mandible (TMJ)styloid process ( thin bone extending inferiorly). houses organs for hearing and balance
• What is the temporal fossa? attachment site for the tmeporalis muscle that is created by the temporal, parietal, frontal, and sphenoid bones
• the ethmoid bone seperates the _ and _ cavities nasal, cranial
• What are some characteristics of the ethmoid bone? many foramen for olfactory nerve fibersforms superior medial nasal conchae creates the superior nasal septum
• What bones make up the hard palate? maxillary and palatine bones
• What are the faucial arches? tissue bands extending downward from velum(anterior arch - palatoglossal arches)(posterior arch - palatopharyngeal arch)

• If the back teeth are affected.... can impact chewing
• What is the point of insertion for all velar muscles? palatal aponeurosis
• what is the function of the levator veli palatini? elevates and retracts velum (primary velar elevator)
• what is the innervation for the levator veli palatini? pharyngeal plexus
• What is the pharyngeal plexus made up of? glossopharyngeal CN and X-vagus-pharyngeal branch
• what is the function of the musculus uvulae? shortens and elevates velumthickens velumincreases force of contact between velum and pharyngeal wall
• what is the innervation of the musculus uvulae? pharyngeal plexus
