Westphalia-Edinger core

The Westphal-Edning nucleus is an accessory nucleus of the oculomotor nerve that provides motor functions to the eye muscles. The Westafl nucleus is located in the medulla oblongata and is about 5 millimeters long. It has two components - the nucleus and the nervous body.

Transient cranial nerve III, the oculomotor nerve, passes through the space between the oculomotor and trochlear nerves in the canal in the cranial cavity and exits through the foramen ovale in the roof of the midbrain. It exits through the upper part of the roof of the midbrain and then runs under the frontal sulcus of the cerebellar hemispheres between the pons and the cerebellum. The oculomotor nerve is the third cranial nerve (C3), it originates from the central processes of the pontine nuclei and the superior part of the pons together form the nucleus of this nerve. The strong process of the nototenin cell is 8 mm wide. This process runs along the white commissure and extends onto the medial surface of the midbrain, covering the olivo-chiasmatic cistern on its sides. In it it forms two large thickenings. In the center of the medulla oblongata, these fibers form several points, which becomes a large point in the anterior lower corner of the upper base; they are known as the accessory nuclei of the oculomotor center, and then are the accessory nuclei of the oculomotor and IX nerves. Each such core consists of two parts - dark and light. Their dimensions are approximately 0.6 x 0.3 x 1.2 cm and contain cells of the second and third types (like similar bodies of the craniopontine nucleus), which give rise to fibers responsible for the transmission of proprioceptive and tendon impulses from the lateral segment of the internal capsules to the bridge; a branch of these fibers also transmits eye movement information about the brainstem drive through the extraocular muscle to the dentate membrane; all this ensures direct transmission
