Ultrastructural observations of efferent terminals in the crista ampullaris of the toadfish, Opsanus tau.

abstract：:Morphometric changes have been studied at the mouse neuromuscular junction (NMJ) as a function of the frequency of stimulation. In vivo stimulation was made at either 10, 25, 50 or 100 Hz. No significant change in the area of NMJ profiles is observed after stimulation. This indicates that stimulation does not change t...
