Key to both figures of the tenth chapter, and their characters.
The first or right [left] 1 figure of this chapter shows the lower maxilla [mandibula] together with the teeth in their anterior aspect. The second figure displays the lower maxilla along with the lower set of teeth drawn in the posterior view. The picture at the beginning of the third chapter of this book at the letter C illustrates the maxilla from the side.
|A 1 , 2||One head [processus condylaris, caput mandibulae] of the lower maxilla, by which it is articulated to the upper maxilla 2 [os temporale, fossa mandibularis].|
|B 1 , 2||Cervix or neck [collum mandibulae] of the head marked A.|
|C 1 , 2||Acute process [processus coronoideus] of one side, into which the temporal muscle builds its insertion.|
|D 2||Hidden in the shading, D marks the large depression in the left [right] figure into which is inserted the muscle hidden in the mouth [m. pterygoideus medialis] which serves with the temporal and masseter muscle to lift the jaw. 3|
|E 1 , 2||Roughness [angulus mandibulae] visible at the posterior and lower part of the maxilla, into which the masseter muscle is inserted.|
|F 2||In the shadowing of the left [right] figure, F marks the foramen [foramen mandibulae] that admits a branch [n. alveolaris inferior] of the third pair of cerebral nerves [nervus trigeminus, n. mandibularis].|
|G 1||Foramen [foramen mentale] by which a small branch [n. mentalis, rami labiales]of the nerve just mentioned drops forward into the lower lip.|
|H 2||On these tubercles [spina mentalis superior et inferior] are implanted the muscles [musculi geniohyoidei] 4 that draw the jaw downward; certain muscles [mm. genioglossi] of the tongue also originate from these.|
