โœฆ Synopsis

Counts of differentiating motor cells over the length of the brachial lateral motor column (LMC) indicate that a large decrease in cell number takes place during the larval period. During the same period an increase in nuclear size of the motor cells occurs with a maximum size attained just following forelimb emergence. Comparison between development of the LMC at the brachial and lumbo-sacral levels indicates a slight lag in brachial LMC development. Cell number remains greater in the brachial LMC than in the lumbo-sacral LMC, but nuclear size is consistently less in the brachial column. Probably no significant change in cell number occurs after metamorphosis, though there is an increase in cell size.

The influence of the peripheral fields upon the development of both motor and sensory centers in the spinal cord was observed by Shorey ( ,09). Later workers have demonstrated that hyper-or hypoplastic development in the motor and sensory centers may be obtained by respectively increasing or decreas
