Edinger Westphal Nucleus is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The Edinger-Westphal Nucleus (EW) is a parasympathetic cranial nerve nucleus located in the midbrain. It provides parasympathetic innervation to the eye via the oculomotor nerve (CN III), controlling pupil constriction and lens accommodation.
Key features include:
This nucleus is affected in various conditions including oculomotor palsies, Holmes-Adie syndrome, and neurodegenerative diseases affecting brainstem function.
The Edinger-Westphal Nucleus (EWN) provides parasympathetic input to the eye, controlling pupillary constriction and lens accommodation.
