terminal nerve
Acronym: trm
The term terminal nerve (trm) refers to one of two nerves in the vomeronasal-terminal nerve complex (vtnc). It is a descending pathway that projects from the accessory olfactory bulb (AOB) in the cranial cavity through the cribriform plate to the vomeronasal organ (VNO) in the olfactory epithelium (OLE) of the nasal cavity ( Wirsig-Wiechmann-2001 ). It is found in the human ( Sonne-2023 ), rat ( Swanson-2004 ) and mouse ( AMBA-2024 ) but likely not in the macaque ( Francia-2014 ). Its prominence in the human is inconsistent with the current (2024) understanding that the VNO is not functionally significant in the human. [See olfactory system (OSY)].
      The other component of the vtnc is the vomeronasal nerve (vmn), which projects from the VNO to the AOB ( Buck-2013 ). The trm and vmn are intertwined in part of vtnc between the VNO and the AOB ( Moran-1995 ). Final 17 Jan 2025.
