I need to memorise the order for the reflex arc, in this order:

Stimuli
Receptor
Sensory neuron
CNS
Motor neuron
Effector
Response

Does anyone know a good, catchy acronym for this? Thanks!

Why do you need an acronym? If you try to fully understand the process, there is no need to memorise anything. Some stimulus is detected by a receptor, this signal is then transmitted along a sensory neurone to the spinal cord. From there, the sensory neurone synapses either directly with a motor neurone or with an interneurone which then synapses with a motor neurone. This signal is then transmitted along the motor neurone to the effector (usually a muscle) which produces a response, in the case of a muscle stretch reflex, the muscle contracts.
