| Abstract | MONEY, K. E., L. BONEN, J. D. BEATTY, L. A. KUEHN, M. SOKOLOFF, AND R. S. WEAVER. Physical properties of &ids and structures of vestibular apparatus of the pigeon. Am. J. Physiol. 220(l) : 140-147. 1971 .-At pigeons’ body temperature (44 C) endolymph has a specific gravity of 1 .OO 17 and a viscosity of 1.19 cp (roughly twice the viscosity of water). Perilymph has a specific gravity of 1.0006 and a viscosity of 0.76 cp. No difference between the specific gravity of the cupula and the specific gravity of endolymph could be detected. The specific gravity of cut lengths of the membranous semicircular ducts with enclosed endolymph is 1.03. On the basis of these findings, it appears that gravity and linear acceleration cannot act directly on the cupula, but they could cause movement or distortion of the membranous labyrinth with resulting endolymph movement and cupular deflection. It is suggested that the semicircular canal reacts quite differently to small and to large stimuli: in response to small angular accelerations, only the proximal part of the cupula (near the hair cells) moves; in response to large angular accelerations, the cupula bends in the classical way and most of the movement is at the distal end. |
