All-or-none Response: Phenomenon in which a muscle fiber contracts completely when exposed to a threshold stimulus, or not at all. When a skeletal muscle is stimulated to contract by a motor neuron a minimum amount of stimulus is needed to start the process of muscle contraction.
The stretch reflex (myotatic reflex) is a muscle contraction in response to stretching within the muscle. It is a monosynaptic reflex which provides automatic regulation of skeletal muscle length.When a muscle lengthens, the muscle spindle is stretched and its nerve activity increases.This increases alpha motor neuron activity, causing the muscle fibers to contract and thus resist the stretching.t is a monosynaptic reflex which provides automatic regulation of skeletal muscle length.
