Flexig bundle

Fleck's bundle is a large connecting structure of gray matter in the region of the posterior spinal cord, located between the lateral parts of the medulla oblongata and the pons: Flexner E.)

This is a bundle of fibers - a collection of nerve fibers that innervate the muscles of the posterior wall of the pharynx and the soft palate. The fibers included in the Flex bundle pass from the pons to the cerebellum, forming its lower surface. The cerebellum contains a representation of all the muscles of the posterior wall of the oropharynx that perform the act of swallowing. Some fibers are sent to the medulla oblongata as part of the medial (Flecke's bundle), lateral (Granet's bundle) and posterior (Leia's bundles) posterior cerebral conductors.

The exit point of the fibers is the temporal fossa of the cortex. During eating (eating), the activity of the fibers is under the control of corticovisceral connections, so at rest they are in a state of depolarization and
