define different disease located on the paralysis of the facial nucleus Edit this paragraph defines the characteristics of supranuclear palsy refers to the injury occurred in the cranial nerve nuclei above segments ,adidas f50 2013, such as the side of the upper motor neurons ,Mercurial Vapor VIII, including cortical bundles or from nuclear cone first region

supranuclear palsy

somatic cell damage can produce contralateral eye fissure below the tongue and contralateral facial muscle paralysis , the performance of the contralateral shallow nasolabial fold or disappear , mouth low down, mouth twisted to one side of the lesion , drooling , can not be drum cheeks, toothy and whistle and other actions ; tongue tongue when the bias contralateral . Edit this paragraph bit different diseases facial nerve paralysis on the characteristics of the nuclear motion on one side of the surface element is characterized by muscle paralysis : contralateral paralysis of facial muscles around the mouth , the side of the pyramidal tract fibers lesions on the side of the muscle under 1/2 ~ 2 /3 of the involuntary movement disappeared, but emotional movement, such as spontaneous laugh,nike mercurial 2013, cry , or other emotional performance of involuntary contractions still exists. Disposable facial small part of the medial frontal gyrus cortical damage, can cause paralysis of the nucleus alone , and can be accompanied by facial muscles Jackson attack. Because the facial nerve and extrapyramidal contact unspoiled , despite the facial nerve supranuclear paralysis, facial muscles still have involuntary movements ( tonic clonic convulsions or hemifacial spasm ) . Lesions in the cerebral hemispheres, without involving the thalamus to the facial nucleus fibers , then supranuclear facial nerve paralysis patients in laughter when not exhibit paralysis, but also involving the hypothalamus of the facial nerve supranuclear palsy , in laughter when they exhibited paralysis . Thalamic lesions, voluntary movement can be retained , but the contralateral " subconscious " emotes lost. Globus pallidus to facial nerve function is interrupted, stiff facial muscle stiffness , tremor, paralysis called masks , but in this " frozen " on the face muscles , or find some randomness and emotional impulses from the muscles caused by contraction. Upper motor yuan ( pyramidal tract , thalamus, globus pallidus ) facial paralysis , muscular atrophy not happen , there is no fasciculations , no electricity reaction of degeneration . Moreover , each accompanied by pyramidal tract , thalamus, basal ganglia and other symptoms. It is actually not difficult to identify.
