During a stretch reflex
WebThe muscle stretch reflex plays an important role in providing feedback during movements. The stretch reflex consists of a monosynaptic response from the direct connection between Ia afferents and motor neurons, that may be followed by polysynaptic reflex activity. WebNov 25, 2024 · Reflexes elicited by application of a stretch stimulus to either. tendons or periosteum, or occasionally to bones, joints, fascia, or. aponeurotic structures are usually referred to as muscle stretch or. deep tendon reflexes.
