What is the primary feature of flaccid paralysis?

Flaccid paralysis is characterized primarily by limp muscles that are unable to contract. This occurs due to damage to the motor neurons or to the neuromuscular junctions that inhibit the ability of the muscles to receive signals to contract. Consequently, the muscles become weak and lack the normal tone and firmness, which results in a noticeably soft appearance and reduced movement capability.

In this condition, the absence of muscle tension and reflex action contrasts sharply with conditions that involve excessive muscle tone or overactive reflexes. Flaccid paralysis often results in an inability to perform voluntary movements, as the involved muscles do not respond appropriately to nerve stimuli. This symptom is indicative of several underlying causes, including neurological disorders, spinal cord injuries, or certain diseases that affect the nervous system.
