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.
Symptoms: Pain, weakness, loss of muscle at the base of the thumb, swelling, paleness, bluish coloration [1] [2] Usual onset: 20 to 50 years of age [1] Types: Neurogenic, venous, arterial [1] Causes: Compression of the nerves, arteries, or veins in the superior thoracic aperture (thoracic outlet), the passageway from the lower neck to the ...
This tension is forced and can cause lesions of the upper roots and trunk of the nerves of the brachial plexus. [25] Motorcycle accidents and sports injuries usually cause this type of injury to brachial plexus. [14] Upward traction also results in the broadening of the scapulo-humoral angle but this time the nerves of T1 and C8 are torn away.
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.
They were the first to identify and describe the symptoms and causes of this syndrome. In their original description, they reported findings from autopsies that showed spinal cord necrosis and multiple tortuous and thickened blood vessels on the surface of the spinal cord. This condition was later called necrotizing myelopathy. [3]
The causes of pelvic floor dysfunction aren’t well understood. Experts know that weakened muscles and connective tissue in the pelvis can contribute to it, as can injuries to the pelvis.
Bardet–Biedl syndrome is a pleiotropic disorder with variable expressivity and a wide range of clinical variability observed both within and between families. The most common clinical features are rod–cone dystrophy, with childhood-onset night-blindness followed by increasing visual loss; postaxial polydactyly; truncal obesity that manifests during infancy and remains problematic ...
Other symptoms include hoarseness, nausea, vomiting, a decrease in sweating, problems with body temperature sensation, dizziness, difficulty walking, and difficulty maintaining balance. Lateral medullary syndrome can also cause bradycardia , a slow heart rate, and increases or decreases in the patient's average blood pressure.
