Final answer:
The correct sequence is Stimulus, Reception, Transmission, Effector, starting with the detection of a stimulus by receptors and ending with an effector generating a response.
Step-by-step explanation:
The correct sequence of events for a stimulus to an effector response is: Stimulus, Reception, Transmission, Effector. First, a stimulus is detected by receptors. Next, these receptors send a signal to a control center, typically the brain, where the signal is processed. The control center then sends a signal through the nervous system, a process known as transmission, to the effector. The effector, which can be a muscle or a gland, acts to respond to the initial stimulus to maintain homeostasis or generate a discrete response.
