Middle Ear Anatomy

The stapes in the middle ear is in direct contact with the:

• Round window

• Oval window

• Eustachian tube

• Tympanic membrane

The middle ear:

• Lies within the temporal bone and is filled with air

• Lies within the occipital bone and is filled with air

• Lies within the temporal bone and is filled with perilymph

• Lies within the bony labyrinth and is filled with fluid

Movement of the head is detected by the:

• Vestibule

• Semi-circular canals

• Cochlea

• Organ of Corti

The malleus of the middle ear is in contact with the:

• Oval window

• Tympanic membrane

• Saccule

• Round window

The organ of Corti is concerned with the sense of:

• Hearing

• Balance

• Sight

• Taste

The function of the ossicles is to:

• Transmit sound waves across the middle ear cavity

• Determine the position of the head relative to the earth

• Detect head movement

• Equalise the air pressure between the middle ear and the environment

The structures that make up the labyrinth apparatus in the ear are the:

• External ear canal and pinna

• Cochlea and semi-circular canals

• Organ of Corti and ossicles

• Eustachian tube and ossicles

The Eustachian tube is a channel that connects the:

• External ear to the middle ear

• Middle ear to the inner ear

• Pharynx to the middle ear

• Pharynx to the inner ear

The structure responsible for balance in the ear is the:

• Vestibule

• Cochlear duct

• Organ of Corti

• Semi-circular canals

The vibrations of the ossicles are transmitted through the:

• Round window

• Oval window

• Cochlear duct

• Organ of Corti
