Question

Quizplus · Accepted Answer

The correct sequence for a somatic reflex like the knee-jerk reflex starts with the stimulus being recognized by a receptor (6), followed by the creation of graded generator potentials (3). These potentials then propagate toward the CNS (2), where a synaptic contact is made and the signal is integrated (5). Subsequently, action potentials propagate towards the periphery (4), leading to muscle contraction and movement (1).
