Physiological and developmental implications of motor unit anatomy. There is increasing evidence that the architectural design and arrangement of the fibers within a motor unit have important physiological and developmental ramifications. Limited data, however, are available to directly address this issu.....
David J.Slutsky, inPeripheral Nerve Surgery, 2006 Motor Unit Anatomy Themotor unitis composed of theanterior horn cell, itsperipheral nerveand multiple terminal axons, each innervating many individual muscle fibers. A skeletalmuscle fascicleconsists of 20 to 60 fibers surrounded by a connective tissue...
After insertion, the needle can be completely removed, leaving the recording microwires in situ. The method allows stable recording of a motor unit during natural movement of the hand and fingers. The identity of a given single motor unit was reflected in the form and amplitude of the motor ...

There was a significantly increased proportion of type-SO muscle fibers and a decrease in the fast muscle fibers (especially type FOG) in 9 mo reinnervated MG. Together with the unchanged proportions of motor-unit types, this led to... RC Foehring,GW Sypert,JB Munson - 《Journal of Neuro...
Studies of Some Twitch and Fatigue Properties of Different Motor Unit Types in the Ankle Muscles of the Adult Cat Contractile responses of motor units in the gastrocnemius, soleus and pretibial flexor muscles of adult cats were elicited by intracellular stimulation of ...

First defined by Sherrington in 1925, themotor unitis the combination of analpha motoneuronor abeta motoneuron(or motor neuron) and the set of extrafusal striated muscle fibers (called themuscle unitportion) that are innervated by it.Gamma motoneuronsthat exclusively innervate specialized muscle fi...
An alternative hypothesis, that the ontogenetic change in activity pattern results from growth changes in the anatomy of the masseter, may be a more likely explanation. 展开 关键词: NEUROMUSCULAR DEVELOPMENT MASTICATORY MUSCLES MOTOR UNITS DOI: 10.1016/0003-9969(91)90116-C ...
