Synaptic Aspects of Hypogravity Motor Syndrome

Abstract

Abstract—This paper provides a review of studies on the effects of hypogravity on neuromuscular system function. It is known that exposure to microgravity causes a series of events that occur in the neuromuscular system, leading to the development of so-called “hypogravity motor syndrome.” Despite a large number of publications related to the pathogenesis of the hypogravity motor syndrome, the decrement in motor function is largely attributed to the changes in the morphofunctional characteristics of skeletal muscles. However, based on the information presented in this paper that provides insight into the processes occurring in motor units the under condition of near weightlessness, a synaptic transition also appears to be essential.
