Primary afferent cell bodies are located within the olfactory epithelium of the nasal mucosa, projections from these cell bodies are the olfactory nerve fibres. The olfactory nerve is a sensory nerve and is composed of many '''Special Visceral Afferent''' fibres. The fibres are formed into bundles that are referred to as 'Olfactory filaments'. The olfactory nerve passes through the [[Skull and Facial Muscles - Anatomy & Physiology#Ethmoid Bone (os ethmoidale)|'''Cribiform plate''']] and is surrounded by meningeal sheets including the [[Meninges - Anatomy & Physiology#Subarachnoid_Space|sub-arachnoid space]]. The olfactory nerve terminates at the [[Forebrain - Anatomy & Physiology#Olfactory_Bulb|olfactory bulb]]. The horse also has nerves which arise from the nasal septum that course into the olfactory bulb, along with the '''vomeronasal nerve''' arising from the '''vomeronasal organ'''. Neurons within the olfactory bulb project through the lateral and medial olfactory tracts, which then send fibres to the medial forebrain bundle, amygdala, septal nuclei and habenular nuclei.
