Which structure contains motor axons only?

Is the statement below True or False? If a neurotransmitter opens a chemically-gated potassium channel, an IPSP will result.

Is the statement below True or False? Parasympathetic nerves arise primarily from the brainstem and sacral area of the spinal cord, whereas sympathetic nerves arise primarily from the thoracic area of the spinal cord.

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.
