MORPHOLOGICAL FEATURES OF ENZYMATIC ACTIVITIES ZONES STRUCTURES OF NEUROMUSCULAR SYNAPSES LATERAL MASSETER OF WHITE RATS ON DISPERSED FOOD FEEDING
The aim of the study was to study the effect of the impact of food on dispersed histomorphological features of structure enzymatic activities zones of neuromuscular synapses lateral masseter. The experimental studies were conducted on male outbreed white rats. It has been shown that dispersed food feeding causes changes in the functional role of the lateral masseter muscle during mastication, being shown in more difficult differentiated movements of this muscle associated with processing in the oral cavity dispersed food, unusual for this type of animals. Consequence of lateral masseter adaptation to the functional load change was the increase in the relative amount of complex enzymatic activities zones of neuromuscular synapses and amplification of their structure, the increase relative number and area of enzymatic activities zones per one muscle fiber.
