Task: Question Answering
Input (English): passage: The crista ampullaris itself is a cone-shaped structure, covered in receptor cells called ``hair cells''. Covering the crista ampullaris is a gelatinous mass called the cupula. Upon angular acceleration (rotation), the endolymph within the semicircular duct deflects the cupula against the hair cells of the crista ampullaris. The hair cells respond by stimulating neurons that innervate them.
 question: is a structure found in the crista ampullaris?
Output (English): No
