Can lead to gastroparesis (delayed stomach emptying), difficulty swallowing (dysphagia), or cardiovascular instability. Diagnostic Tools for Nerve Conditions

At the heart of this complex network are the , which emerge directly from the cerebrum and brainstem rather than traveling through the spinal cord. These paired nerves serve as the command infrastructure for our primary senses, facial movements, and vital autonomic functions.
The patient closes their eyes and identifies a familiar scent, like coffee or soap. As the largest cranial nerve, the trigeminal splits
