The Abducens Nerve: Anatomy and Pathology.

Area of Science:

• Neuroscience
• Radiology
• Anatomy

Background:

• The abducens nerve (sixth cranial nerve) is a purely motor nerve.
• It originates in the brainstem and innervates the lateral rectus muscle.
• Its long anatomical course involves structures like the inferior petrosal sinus and Dorello's canal.

Purpose of the Study:

• To review the detailed anatomy of the abducens nerve.
• To demonstrate the imaging features of common pathologies affecting the abducens nerve.

Main Methods:

• Review of anatomical literature.
• Compilation of imaging findings from various pathologies affecting the abducens nerve.

Main Results:

• Detailed description of the abducens nerve's anatomical pathway.
• Illustrations and descriptions of imaging findings for diseases impacting the nerve.

Conclusions:

• Understanding abducens nerve anatomy is crucial for interpreting imaging findings.
• Abnormalities in adjacent neurological structures can affect the abducens nerve function.
