Atonicity

Atonicity refers to a state of lacking or deficient muscular tone, characterized by a flaccid or relaxed state of the muscles. This can result in weakness, limpness, and an inability to maintain posture or produce effective movement. It is often a symptom of underlying neurological or muscular disorders, impacting voluntary and involuntary muscle functions. The severity of atonicity varies widely depending on the cause and extent of the affected muscles, ranging from subtle changes in muscle firmness to complete paralysis. In a broader sense, atonicity can extend to the absence of vigor, enthusiasm, or responsiveness in any system, not just physical.
