| 11. | The "'infratemporal fossa "'is an irregularly shaped cavity, situated below and medial to the zygomatic arch.
|
| 12. | The zygomatic arches ( cheekbones ) spread broadly.
|
| 13. | The zygomatic arches ( cheekbones ) are slender.
|
| 14. | Their zygomatic arches form elongations of the maxillae.
|
| 15. | The upper molars extend onto the zygomatic arch and are considerably smaller than their neighbouring premolars.
|
| 16. | The masseter muscle does attach directly behind the zygomatic arch in a manner very different from sciuromorphs.
|
| 17. | The circumocular patch does not extend below the zygomatic arch, and the stripe between its eyes is wide.
|
| 18. | The zygomatic arch is expanded laterally and dorsally and is used as a resonating chamber-a unique feature among mammals.
|
| 19. | Unlike most other mammals, shrews lack zygomatic bones ( also called the jugals ), so have incomplete zygomatic arches.
|
| 20. | The zygomatic arches are massive with the right one displaying many traces of deformations, probably due to fractures and injuries.
