The internal branch of the superior laryngeal nerve (iSLN) conveys sensory afferent information from receptors located in the laryngeal mucosa. The objectives of this study were: to determine the specific anatomical location of iSLN cell bodies within the nodose ganglion; to ascertain whether the jugular ganglion might also contain iSLN afferent bodies; to(More)
To further the understanding of gastrointestinal function in this species, and in particular to advance our own work concerning central emetic pathways, the cytoarchitecture and the distribution of eight neurochemicals were studied in the ferret dorsal vagal complex (DVC; area postrema, nucleus of the solitary tract [nTS] and dorsal motor nucleus of the(More)
The ethmoidal nerve innervates the nasal mucosa and constitutes the afferent limb of several upper airway protective reflexes. Protective reflexes, such as sneezing, coughing, and apnea, are those reflexes that either expel foreign substances from the respiratory tract or stop them from gaining access to the lungs. The afferents for nasal receptors are(More)
Stimulation of the nasal mucous membrane can initiate protective reflexes, particularly sneezing and apnea. Very little is known about the receptors in the nasal cavity responsible for initiating these reflexes, which are thought to be mediated by trigeminal rather than olfactory pathways. In the cat, the ethmoidal branch of the ophthalmic division of V(More)
The afferents of the nasal receptors responsible for many upper airway protective reflexes are carried in the ethmoidal branch of the ophthalmic division of the trigeminal nerve. Previous electrophysiological studies indicate that a significant number of ethmoidal afferents respond to noxious stimuli applied to the nose. The objective of the present study(More)
