Question
Label the diagram of the ear.
Markscheme
I eardrum / tympanic membrane
II cochlea
III auditory/vestibulocochlear nerve
IV semicircular canals
Award [1] for every two correct.
Examiners report
Candidates did surprisingly poorly on this simple task of naming the structures of the ear. Structure IV was often incorrectly named. It was unclear why so many indicated that these were the bones of the middle ear as this is indicated in E.2.6.
