Regions used for quantitative analysis of periosteal activity
| Bone | Region | Abbreviation for region | Classification of activity* |
|---|---|---|---|
| Mandibular ramus (R) | Caudal border | ||
| Condylar area | R(CBC) | Appositional only | |
| Angular area | R(CBA) | Appositional only | |
| Dorsal border | R(DB) | Appositional and resorptive | |
| Rostral border | R(RB) | Appositional and resorptive | |
| Ventral border | R(VB) | Appositional only | |
| Lateral surface, foramen area | R(MFL) | Appositional only | |
| Medial surface, foramen area | R(MFM) | Resorptive only | |
| Remainder of lateral and medial surfaces | R(ML) | Appositional and resorptive | |
| Hard palate (P) | Oral surface | P(O) | Appositional only |
| Nasal surface | P(N) | Resorptive only | |
| Caudal border | P(CB) | Appositional only | |
| Zygomatic arch (A) | Dorsal border | A(DB) | Appositional only |
| Ventral border | A(VB) | Appositional only | |
| Body of zygomatic bone (Z) | Lateral surface | Z(L) | Appositional only |
| Medial surface | Z(M) | Appositional and resorptive | |
| Zygomatic flange (Fl)† | Lateral surface | Fl(L) | Appositional only |
| Medial surface | Fl(M) | Appositional and resorptive | |

| Medial surface | T(M) | Resorptive only | |
*
The 1-mm-long sites that composed these regions are illustrated in Fig. 1. Five regions, R(DB), R(RB), R(ML), Z(M) and F(M) were typically composed of both appositional and resorptive sites, which were separated for analysis.
†
The zygomatic flange is the ventral extension of the zygomatic bone ventral to the zygomatic process of the temporal bone. See Fig. 1.
