Nov 22, 2022 · Unlike crocodilians (Lessner and Holliday 2020) or squamates (Macrì et al. 2019), turtles have virtually no olfactory tracts, and the olfactory bulbs are located immediately anterior to the cerebrum (Fig. 4.2).
Apr 4, 2015 · During hibernation, turtles reduce ATP consumption in neural tissue by reducing membrane permeability and thus the need for pump-mediated restoration of ionic balance. This phenomenon has been observed in turtle neurons for voltage-gated Na + channels, the oxygen-sensitive calcium-activated K + channels, as

Sep 1, 2007 · They are innervated by short olfactory nerves that run into long olfactory tracts, which project caudally to olfactory bulbs. Animals with elongated snouts (eg, alligators, monitor lizards, aquatic turtles) have long olfactory tracts [1] leading from the olfactory bulbs to the cerebrum.

Jun 2, 2023 · Odorant receptors (ORs) are the major olfactory receptors in turtles; they are classified as class I and II ORs, distinguished by their primary structure. Class I ORs are suggested to be receptive to water-soluble ligands and class II ORs to volatile ligands.
Nov 1, 2018 · In many turtles including the Reeve’s turtle Mauremys reevesii, the upper chamber epithelium contains ciliated olfactory receptor neurons (ORNs) and the lower chamber epithelium contains microvillous ORNs.
In turtles, the olfactory organ consists of the upper chamber epithelium (UCE) and the lower chamber epithelium (LCE). The UCE and the LCE line the upper and lower chambers of the nasal cavity, respectively, and are generally referred to as the olfactory epithelium and the vomeronasal organ.
