ADDITIONAL SKULL FEATURES • Major sutures • Paranasal sinuses • Hyoid bone
Maxilla • Forms the majority of the skeleton of the face and the upper jaw • Contains the maxillary sinus • Articulates with the frontal, sphenoid, nasal, vomer, and ethmoidbones; inferior nasal concha, palatine, lacrimal, and zygomatic bones; and septal and nasal cartilages
Mandible • Forms the lower jaw • Described as horseshoe shaped • All muscles of mastication attach to the mandible • Consists of body of mandible, ramus, coronoid process, condylar process, alveolar process
Lacrimal Bone • Small and rectangular in shape • Very thin and fragile • Forms a small portion of medial wall of the orbit • Articulates with frontal process of the maxilla, orbital plate of the ethmoid bone, frontal bone and inferior nasal concha • The region that articulates with the frontal process of the maxilla forms the lacrimal fossa →the location of the lacrimal sac • The inferior part of the lacrimal forms a small portion of the lateral wall of the nasal cavity
Nasal Septum • Septal Cartilage • Ethmoid bone • Vomer
Base of Nasal Cavity • Maxilla – Palatine Process of Maxilla • Palatine Bone – Horizontal Plate of Palatal Bone
Superior Border of Nasal Cavity • Nasal Bone • Frontal Bone • Ethmoid Bone
Lateral Border of Nasal Cavity • Ethmoid Bone • Lacrimal Bone • Inferior Nasal Concha • Palatine Plate
What is foramen? • A foramen (pl. foramina) is an opening. • Foramina allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another.
