The spatial distribution of fibers belonging to a single motor unit was analyzed in 10 motor units from the tibialis anterior of the cat 6 months after denervation and self-reinnervation of the anterior (superficial) compartment of the muscle. After self-reinnervation, the distribution patterns of ...
Injuries to the CPN produce a foot dorsiflexion palsy, due to the loss of innervation of the tibialis anterior, extensor hallucis longus, extensor digitorum longus and peroneal muscles. In turn, this leads to foot and digital drop, and progression to the abnormal gait known as steppage gait. ...
In response to colchicine, the endplates of the slow muscles sprouted more than those of fast muscles while the innervation of slow fiber types sprouted less than that of fast fiber types. Furthermore, intranodal sprouts were more prevalent in slow muscles and ultraterminal sprouts more numerous...
The morphology and nerve innervation patterns of eight tibialis anterior (TA) and medial gastrocnemius (MG) muscles from human cadavers were examined. TA has three distinct partitions, two of which lie posteriorly. The anterior aspect of the muscle has one partition (head A) whose fibers are ...

anterioranatomyMuscleinnervationsElectricalstimulationObjective Percutaneous electrical stimulation of the motor point permits selective activation of a muscle. However, the definition and number of motor points reported for a given muscle varies. Our goal was to address these problems. Methods The area, ...
4. Innervation ratios and specific tensions for all experimental motor units were within the ranges of those reported for tibialis anterior motor units in control cats. Thus, it appears that the decrease in maximum tension of the fast motor units was primarily related to a reduction in fibre ...
