pyramidal deficit Explanation: - motor deficiency (općenito govoreći) ... the distinction between pyramidal and extrapyramidial motor systems. The former governing fine distal activity and the latter gross, proximal/axial activity (Davidoff 1990, Lawrence and Kuypers 1968a, 1968b, Sarnat 1989) (with hemispherectomy loss of individual finger movement is a pyramidal deficit, whereas gait and use of the paretic arm as a "helper" derive from the extrapyramidal system: our cases are motorically and anatomically equivalent to bilateral hemispherectomy) Pyramidal Tract (CorticoSpinal) - One of the major Motor Tracts from the Brain to the Spinal Cord. The Pyramidal System is specialized for making discrete movements, its Axons fibers form the Pyramids of the Medulla Oblongata. It originates in the Cortex of the Frontal Lobe. Those corticospinal fibers that synapse directly on lower motor neurons are supposedly those which control voluntary movement of the digits. It is damage to these fibers - resulting in the loss of voluntary movement of the digits - which is the most pronounced deficit resulting from corticospinal/pyramidal tract damage. Vjerojatno je pogreno napisano (to i nije ba rijedak slučaj). |
