• Place the terms (A-H) in the correct order for the hearing pathway.
Answer:
Soundwaves are funneled in the (Auditory canal)
Vibrations push against the (Tympanic membra) which moves the ossicles.
The stapes pushes against the (Cochlear duct)
Movement of the (Stereocilia) causes neurons to send impulses through the(Cochlear nerve) to
the brain.

Answer:
Funneled vibrations push against the eardrum which moves the (Ossicles).
The stapes pushes against the (cochlear duct.
Movement of tiny hairs inside the (organ of corti) causes neurons to send impulsesthrough a
cranial nerve to the (auditory cortex) , located in the (temporal) lobe

Answer: Funneled vibrations push against the eardrum which moves the (Auditory cortex).
Thestapes pushes against the (Organ of Corti).
