Question

Loss of excitatory input from higher centers brings about flaccid paralysis.​

Quizplus · Accepted Answer

Excitatory input from higher centers, such as motor cortex and brainstem, are necessary for muscle contraction. Without these inputs, the muscle fibers do not receive the necessary signals to contract and remain relaxed, resulting in flaccid paralysis. This can occur in conditions such as spinal cord injury or lower motor neuron disease.
