Abstract:
Although granular cell tumours have been demonstrated to have a neural origin, they rarely arise in peripheral nerve trunks. We report a case of granular cell tumour of the ulnar nerve in a 51-year-old man. Though dissectable from the nerve, this intraneural tumour showed microscopic involvement of focal nerve fibres. This tumour tended to infiltrate the nerve in the same manner as a neurofibroma.

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
