Functional Significance of Blood Sinuses around Sense Organs in Some Mammals

  • Takeshi Yohro


Anatomically the presence of venous sinuses around hair follicles characterizes vibrissae or “sinus” hairs, which are mechano-receptors widely distributed in mammals, except man. The functional role of the sinus, however, is not yet clear, and there have been several suggestions on its significance in previous literatures on the anatomy of vibrissae. The purpose of the present paper is to review briefly the probable functional roles of the venous sinus of vibrissae and to describe in this context examples of venous sinuses around sense organs in some mammals, especially in insectivores.
