MACROMORPHOMETRIC STUDY ON PARANAL SINUSES IN A BROWN BEAR (URSUS ARCTOS)

摘要

The aim of the study was to establish the macromorphometric parameters of paranal sinuses and their projections onto the skin in a brown bear. It is shown that the brown bear’s paranal sinuses were similar to these of domestic dogs, and also located between the external and internal sphincters. Data about the colour, texture and amount of the organ' s secretion are provided. According to the present study, the brown bear possessed well developed paranal sinuses.
