Malar Bones {mala, the cheek).—The malar (fig. 28) is thestrong quadrangular bone which forms the prominence of the is divisible into an external and internal surface and four processes,the frontal, orbital, maxillary, and zygomatic. The external surface * The lachrymal bone of the right side, viewed upon its external or orbitalsurface. 1. The orbital portion of the bone. 2. The lachrymal portion; thepiominent ridge between these two portions is the crest. 3. The lower termi-nation of the crest, the hamulus lachrymalis. 4. The superior border whicharticulates with the frontal bone. 5. The posterior border, which articulateswith the ethmoid bone. 6. The anterior border, which articulates with thesuperior maxillary bone. 7. The border which articulates with the inferiorturbinated 46 malak bones. is smooth and convex, and pierced by several small openings, whichgive passage to filaments of the temporo-malar nerve and minutearteries. The internal surface is concave, partly smooth and partlyrough; smooth where it forms part of the temporal fossa, and roughwhere it articulates ^^dth the superior maxiUary bone. The frontal process ascends perpendicularly to form the outerborder of the orbit, and to articulate with the external angular pro-cess of the frontal bone. The orbital process is a thick plate, whichprojects inwards from the frontal process, and unites with the greatala of the sphenoid to constitute the outer wall of the orbit. It ispierced by several small foramina for the passage of temporo-malarfilaments of the superior maxillary nerve. The maxillary process isbroad, and articulates with the superior maxillary bone. The zygo-matic p>rocess, narrower than the rest, projects backwards to unitewith
