• It is often discussed in relation to its function, disorders affecting it, or during anatomical study.

Examples

• Noun:
  • Damage to the sixth cranial nerve can result in an inability to move the eye laterally, a condition known as abducens nerve palsy.
  • The neurologist tested the function of the patient's sixth cranial nerve by asking them to follow her finger to the side.

Advanced Usage
