| Abstract: | The current study was done to provide comprehensive information on the anatomical features of the lips and cheeks of the goat by gross examination and morphometric analysis in addition to scanning electron microscope (SEM). Samples from 12 normal healthy adult goat's heads of both sexes were collected directly after slaughtering. The lips and cheeks were dissected, and specimens were collected for both light and SEM. The lips of goat were soft and mobile. The free border of both lips was characterized rostrally by the presence of labial projections. The number, size, and arrangement of labial projections differed in the upper and lower lips. On the other hand, the buccal papillae were arranged into 6–8 longitudinal rows parallel to the cheek teeth. The length of these papillae decreased caudally while they were absent on the most caudal part of the cheek. Presence of several types and shapes of labial projections and papillae, and buccal papillae suggest a high degree of mechanical adaptation of the lips and cheeks of the goat. This study provides baseline data for clinical studies. This study is the first report to shed light on the morphology of the lips and cheeks of the goat by gross and scanning electron microscopy. |
