GANGLION CELLS IN PORTION OF LINGUAL NERVE SUSPENDING SUBMANDIBULAR GANGLION – A CASE REPORT
Abstract
Haematoxylin and Eosin sections of a submandibular ganglion and its two roots suspended by the lingual nerve, with a portion of the submandibular gland were prepared from tissue obtained from an adult male cadaver during routine dissection. Ganglion cells were present in the submandibular ganglion, in the hilum of the submandibular gland, and in the epineurium, perineurium and within the fascicles of lingual nerve in longitudinal sections. Most parasympathetic ganglia of the head and neck are cell bodies of neurons clumped together, to form tiny ganglia scattered in supporting tissue. The ganglion cells in the nerve were thought to be derived from myelencephalic neural crest cells arrested in their descent along the lingual nerve. A review of recent literature reveals that they are derived from Schwann cell precursors that migrate along nerves.
