Plethodontid salamanders have unique nasolabial grooves that may function as “capillary tubes” to convey chemicals to the vomeronasal organ when these animals nose‐tap. 3H‐proline was placed at the base of these grooves in Plethodon cinereus, and autoradiography revealed large concentrations of radioactive material in the vomeronasal organs. There was no significant accumulation of radioactive material in the main olfactory epithelium. Salamanders with blocked nasolabial grooves lacked… Expand
Pheromonal activation of vomeronasal neurons in plethodontid salamanders
TLDR
It is suggested that a specific population of vomeronasal neurons in a female plethodontid salamander is responsible for transmitting pheromonal information to the brain to produce modifications in behavior. Expand
Structure and function of the vomeronasal organ 2915
, Many animals use their vomeronasal organs to gain direct and specific contact with chemical cues released by congeners and in biological fluids. These cues provide information about theExpand
Structure and function of the vomeronasal organ.
TLDR
The present review gives a short description of the discovery of the vomeronasal organ and the pivotal findings of Jacobson, and the anatomical, biochemical and functional properties of the receptor neurones are described. Expand
Comparative Morphology of Plethodontid Olfactory and Vomeronasal Organs: How Snouts Are Packed
  • E. Dawley
  • Biology
  • Herpetological Monographs
  • 2017
TLDR
Olfactory and vomeronasal organ morphology in several species of salamanders in the Family Plethodontidae ranging from completely aquatic, semiaquatic, terrestrial, to arboreal is examined, indicating the importance of this system for plethodentids. Expand
Olfactory metamorphosis in the Coastal Giant Salamander (Dicamptodon tenebrosus)
TLDR
Examination of the gross morphology and ultrastructure of the olfactory organ of larvae, neotenic adults, and terrestrial adults of the Coastal Giant Salamander suggests that some features of the metamorphic changes described here are characteristic of all salamanders, while others appear unique to D. tenebrosus. Expand
The Lack of Nasolacrimal Ducts in Plethodontid Salamanders?
TLDR
Bayesian ancestral state reconstruction resulted in the presence of nasolacrimal ducts on the branch leading to Plethodontidae and both subfamilies within PlethODontidae, with two independent losses in Desmognathus and Eurycea. Expand
Sexual and seasonal differences in the vomeronasal epithelium of the red‐backed salamander (Plethodon cinereus)
TLDR
The functional significance of sexual and seasonal differences in the vomeronasal organs of P. cinereus may relate to the neurogenesis of specialized receptors for courtship and mating. Expand
Comparative anatomy and physiology of chemical senses in amphibians
TLDR
This chapter introduces the chemosensory systems of tetrapods, then focuses on their structure and function in amphibians, and the olfactory, vomeronasal, and gustatory systems. Expand
Correlation of Salamander Vomeronasal and Main Olfactory System Anatomy with Habitat and Sex: Behavioral Interpretations
TLDR
This paper presents a preliminary survey of variation of vomeronasal and main olfactory system morphometrics for salamanders with different habitat requirements and for both sexes and attempts to correlate this anatomical variation with ecological and sexually dimorphic behavioral variation. Expand
A re‐examination and re‐evaluation of salamander orbital glands
TLDR
Analysis of the orbitonasal region of salamanders from three families was histologically examined and it was concluded that there may be a global pattern in the location of tetrapod orbital gland development. Expand

Organization of the vomeronasal organ in a plethodontid salamander
TLDR
Adaptations in the nasal structure of Plethodon cinereus suggest a specific mechanism of odorant delivery to the vomeronasal organ in plethodontid salamanders not found in other salamander families. Expand
Chemical access to the vomeronasal organs of garter snakes
TLDR
Garter snakes tongue-flicked cotton swabs soaked in a mixture of earthworm extract and 3H-proline revealed large accumulations of radioactive material, as revealed by autoradiography, in the vomeronasal organs. Expand
EVOLUTION OF VOMERONASAL ORGANS IN VERTEBRATES
  • G. Bertmar
  • Biology, Medicine

TLDR
A theory on the evolution of the VN organs from fish to mammals is presented, mainly based on comparisons of the position, gross and fine structure, and the ontogeny of the organs. Expand
Additional Observations on the Function of the Nasolabial Grooves of Plethodontid Salamanders
TLDR
Histochemical studies on the distribution of diphosphorylating and oxidative enzymes and esterases in the olfactory bulb of the squirrel monkey and the structure of the Pacinian corpuscle reveal a mechanistic basis for directional sensitivity in cochlear and sensory receptors. Expand
Efferent control of stimulus access to the hamster vomeronasal organ.
TLDR
The vomeronasal organ can be adequately stimulated by activation of the pumping mechanism in the presence of odour, and the time course of neuronal response in the accessory olfactory bulb is more rapid than predicted and cannot be ruled out as a possible sensory pathway in many odour related behaviours.

TLDR
Most workers employ this tenable model of amphibian affinities; however, additional data are needed to accept this hypothesis, particularly for the apodans. Expand

TLDR
It is suggested that body secretions and/or faecal material may act as signal markers during territorial defence in red-backed and Shenandoah salamanders as well as in other Plethodon species. Expand
