Anatomy of Ear: Middle Ear

Middle ear muscles are innervated by 

a). Cranial nerve VII
b). Cranial nerve V
c). Cranial nerve VII and VIII
d). Cranial nerve VII and IX
e). Cranial nerve V and VII
















correct answer: e


The cranial nerve VII, also known as facial nerve, innervates the stapedius muscle in middle ear and muscles of facial expression.

The cranial nerve V, also known as trigeminal nerve, innervates the tensor tympani muscle. It provides sensory and motor innervation to the face.

The cranial nerve VIII, also known as vestibulocochlear nerve, carries information about hearing and balance.

The cranial nerve IX, also known as glossopharyngeal nerve. It controls muscles in the oral cavity and upper throat (responsible for swallowing). 

The cranial nerve X, also known as vagus nerve innervate the muscles of palate, pharynx, larynx, ear canal, and pinna etc.
