The Sensura Neglecta in the Pigeon: A Scanning Electron and Light Microscope Study.
DEFENCE AND CIVIL INST OF ENVIRONMENTAL MEDICINE DOWNSVIEW (ONTARIO)
Pagination or Media Count:
Both scanning electron and light microscopy have been used to observe the tiny sensura neglecta which is located in the inferior utricula sinus of the vestibular labyrinth in the pigeon. Observations indicate that the sensura neglecta in the pigeon has both crista- and macula-like features. It is hypothesized that this is reasonable from an evolutionary and teleological point of view. It is further suggested that regardless of its similarities to the statolithic and canalicular organs, the mode of stimulation of the neglecta can best be described by analogy to the culmen type of system associated with the auditory papilla of the lizard.
