-------- Original Message -------- Subject: Labeling Landmarks. Date: Tue, 1 Nov 2011 19:16:33 -0400 From: Daniel Arranaga <[email protected]> To: [email protected] Dear morphmetricians, I am new to the field of geometric morphometrics and have been researching primate mandibular morphology in relation to diet. I have landmark names and definitions for all of my landmarks except for three. I have been looking around to see if there are proper names for three of my landmarks along the symphysis. I made up "gnathion internal" for landmark 13. I was hoping somebody here might be familiar with mandibles. Landmarks in question are 13, 16, & 17. Thank you, Daniel Arrañaga Landmark Definition 1. Gonion Point along rounded posterioinferior corner of mandible where line bisecting angle between body and ramus would hit 2. Condylion mediale Most medial point on mandibular condyle 3. Condylion laterale Most lateral point on mandibular condyle 4. Mandibular notch Most Inferior point on mandibular notch 5. Coronion Most superior point on coronoid process 6. Posterior ramus Point at posterior margin of ramus at level of M_3 7. Anterior ramus Point at anterior margin of ramus at level of M_3 8. M_3 Internal Point on alveolar bone just posterior to midline of third molar on lingual side 9. M_1 External Point on alveolar bone just posterior to midline of first molar 10. M_1 Internal Point on alveolar bone just posterior to midline of first molar on lingual side 11. Mental Foramen Point in middle of mental foramen 12. Gnathion Most inferior midline point on symphysis 13. Gnathion /Internal/ Most inferior midline point on the lingual side of mandible 14. Infradental Midline point at superior tip of septum between mandibular central incisors 15. Mandibular orale Most superior midline point on lingual side of mandible between two central incisors 16. -- Midline Point on the lingual side of the mandible at the level of M_2 17.-- Midline point on the symphysis midway between the infradental and the Gnathion
