The middle cerebellar peduncle is the largest of the three cerebellar peduncles. It connects the pons and cerebellum.It consists almost entirely of fibers passing from the pons to the cerebellum (fibrocerebellar fibers); the fibers arise from the pontine nuclei and decussate within the pons before entering the peduncle [1] to end in the contralateral cerebellar hemisphere.
Cerebellar stroke syndrome is a condition in which the circulation to the cerebellum is impaired due to a lesion of the superior cerebellar artery, anterior inferior cerebellar artery or the posterior inferior cerebellar artery.
Problems with balance can occur when there is a disruption in any of the vestibular, visual, or proprioceptive systems. Abnormalities in balance function may indicate a wide range of pathologies from causes like inner ear disorders, low blood pressure, brain tumors, and brain injury including stroke.
The pontine nuclei (or griseum pontis) are all the neurons of the ventral pons. Corticopontine fibres project from the primary motor cortex to the ipsilateral pontine nucleus; pontocerebellar fibers then relay the information to the contralateral cerebellum via the middle cerebellar peduncle .
The entire pathway begins and ends in the cerebral cortex, and its entire course is the following: [2] (Motor and sensory areas of) cerebral cortex → corticopontine fibers → (ipsilateral) nuclei pontis (synapse) → pontocerebellar fibers (decussation within pons) → middle cerebellar peduncle → (contralateral) (cerebellar cortex and (collaterals) dentate nucleus of) posterior lobe of ...
Vocal cord dysfunction (VCD) is a condition affecting the vocal cords. [1] It is characterized by abnormal closure of the vocal folds, which can result in significant difficulties and distress during breathing , particularly during inhalation .
The exercises mentioned above can be done to help rehabilitate from mild cases of the injury. However, in more serious brachial plexus injuries surgical interventions can be used. [ 35 ] Function can be restored by nerve repairs, nerve replacements, and surgery to remove tumors causing the injury. [ 36 ]
However, fibromyalgia is typically associated with fatigue, depression and cognitive dysfunction. The anatomic distribution and characteristic of the pain also differ. While the fibromyalgia pain is generalized, bilateral and typically involving muscles above and below the waist, the MPS pain affects a particular region of the body such as the ...
