Which of these sequences incorrectly describes the order of events in a particular nervous system process?

pain sensors in the finger --> stimulate efferent neurons --> enter
ventral horn of spinal cord --> exit dorsal horn of spinal cord -->
stimulate afferent neurons --> cause skeletal muscles to contract

light passes through the cornea --> through the pupil --> through the
lens --> is detected by the retina --> processed by bipolar neurons --
> passes to brain along CN II

sound passes through the ext. auditory canal --> causes tympanic
membrane to vibrate --> causes ossicles to vibrate -> passes through
oval window --> passes into the cochlea --> is detected by spiral
organ --> passes to brain along CN VIII
