Hearing & Balance

A series of sacs and canals in the inner ear's labyrinth responsible for sensing movement and position of the head:

• vestibular apparatus

• basilar membrane

• tympanum meatus

• tympanic membrane

The outer ear that you can see on the side of your head:

• pinna

• eardrum

• tympanum

• ossicles

The spiral part of the inner ear's labyrinth responsible for sensing and transducing sound waves:

• hair cells

• ossicle

• cochlea

• tympanic membrane

Three small bones in the middle ear that amplify the vibrations from the eardrum and apply them to the oval window:

• eardrum

• auditory ossicles

• oval window

• pinna

A thin, translucent, cone-shaped piece of connective tissue that divides the external and middle ear, also known as the eardrum:

• auditory ossicles

• tympanic membrane

• oval window

• semicircular canals

Three structures that sit in different planes and are used to sense rotations of the head in each plane:

• utricle

• semicircular canals

• saccule

• pinna

The hole in the side of your skull through which sound is funneled:

• external acoustic meatus

• auditory ossicles

• incus

• semicircular canals

The membrane that marks the boundary between the middle and inner ears, this receives vibrations from the ear bones:

• oval window

• meatus

• auditory ossicles

• tympanic membrane

The maze-like inner ear, with a bony shell filled with membranous sacs and ducts:

• meatus

• labyrinth

• malleus

• incus

The part of the inner ear that contains the special sensory cells that transduce sound vibrations into neural electrical signals:

• organ of corti

• basilar membrane

• tympanum meatus

• tympanic membrane
