General Inspection

During the general inspection of the cranial nerves, we should look for whether the patient has any ptosisabnormal eye movements and facial asymmetry. We should also inspect for whether there are any neuro-cutaneous features (for example in patients with tuberous sclerosis and neuro-fibromatosis), syndromal features etc.
