A lower motor neuron lesion: One major characteristic used to identify a lower motor neuron lesion is flaccid paralysis — paralysis accompanied by loss of muscle tone.

Hypotonia or atonia- Tone is not velocity dependent.

Muscle wasting, fasciculations and fibrillations are typically signs of end-stage muscle denervation and are seen over a longer time period. Another feature is the segmentation of symptoms – only muscles innervated by the damaged nerves will be symptomatic. Movimientos involuntarios incontrolados sincinesias.

Tono muscular y reflejos musculares. Este ascenso del tono se debe a que el arco reflejo pierde influencias que normalmente recibe de las estructuras nerviosas superiores, estando el arco reflejo desinhibido. La resistencia que nota el explorador depende de la velocidad del desplazamiento.

Resistencia ante los movimientos pasivos debido a la espasticidad. La resistencia es mayor al principio hasta que cede. Which of the following is NOT a bone of the neurocranium?
