Certain aspects of the facial and trigeminal nerves of the ox (Bos taurus L.)

Abstract

The author dissected thirty bovine heads to study the motor and sensory nerve supply to the zygomatic region. The motor and sensory branches to this region are supplied by the auriculopalpebral and auriculotemporal nerves respectively. It is suggested that these branches be named zygomatic branches. The buccal nerve constantly detaches a deep temporal branch, gives rise to glandular branches to the hard and soft palate and sends a communicating branch to the lingual nerve. Connections could be demonstrated between these branches and the otic ganglion and it is suggested that they carry visceral motor components. Observations on the otic and mandibular ganglia, the relations of the pterygoid, masticatory and buccal nerves and the variable course of the chorda tympani are recorded.
