Area between bony labrinyth and membranous labrinth contain
Perilymph
Framework of the inner ear is known as the
Bony labyrinth
Bony labyrinth contains
Membranous labyrinth, which makes up the sub-structures of the inner ear
Membranous labyrinth contains
Endolymph
Order of the ossicles
Malleus (hammer), incus (anvil), stapes (stirrup)
Cochlea
Inner ear, responsible for hearing, spiral shaped, divided into three layers referred to as scalae
Inner and outer scalae filled with _________ while the middle layer is suspended between two membranes and contains _____________
Perilymph, Organ of Corti
Inner ear hair cells protrude from _______ into the ________
Basilar membrane, organ of corti
Place theory
Place theory in hearing suggests that different frequencies of sound are perceived because they stimulate specific locations along the basilar membrane of the cochlea.
Left hemisphere specializes
Speech processing
Right hemisphere specializes in
Processing background noise and music
Semicircular canals contain
Endolymph
Semicircular canals detect
Rotational acceleration
Ampulla
widened, bulb-like structure at the base of each semicircular canal in the inner ear that contains sensory hair cells to detect rotational movement.
