If the tendon attached to the olecranon of the ulna is tapped sharply, it causes the muscle attached to it to stretch. This stretch then triggers a reflex that ends in contraction of the muscle attached to the olecranon of the ulna. Match the the seven steps of a reflex pathway to the specific structures and events that are involved in the particular reflex pathway described above . Note: Not every specific structure/event will be used as an answer.  

Which structure contains motor axons only?
