Fate of Otic and Nasal Capsules in Buffalo (Bubalus bubalis)

Abstract

The present work was undertaken on 55 buffalo embryos and foetii ranging from 26 to 310 days. The
otocyst development was recognized first at 26 days and surrounded by an otic capsule at 27 days. The otic
and nasal capsules were in cartilaginous form at 45 days. The otic capsule had formed the tympanic bulla at 62
days and petrous temporal at 111 days. The ethmoid, turbinates, nasal septum and nasal cartilages were
derived from the mesenchyme of nasal capsule. Distinct nasal cartilages were observed at 61 days. Ossification
of nasal capsule was evident first in perpendicular plate of ethmoid at 85 days.
