Is cochlea involved in equilibrium?
The inner ear (also called the labyrinth) contains 2 main structures — the cochlea, which is involved in hearing, and the vestibular system (consisting of the 3 semicircular canals, saccule and utricle), which is responsible for maintaining balance.
What is the apex of the cochlea?
The cochlea (plural is cochleae) is a spiraled, hollow, conical chamber of bone, in which waves propagate from the base (near the middle ear and the oval window) to the apex (the top or center of the spiral).
What do utricle and Saccules detect?
The utricle and saccule are the two otolith organs in the vertebrate inner ear. They are part of the balancing system (membranous labyrinth) in the vestibule of the bony labyrinth (small oval chamber). The utricle detects linear accelerations and head-tilts in the horizontal plane.
What part of the ear is responsible for dynamic equilibrium?
semicircular ducts
The cristae of the semicircular ducts, which form one of the two sensory organs of balance (the second being the maculae of the utricle and saccule), respond to rotational movements and are involved in dynamic equilibrium.
Is the cochlear duct part of the scala vestibuli?
The cochlear duct is another bony hollow tube that sits between the scala vestibuli and the scala tympani. The cochlear duct contains endolymph. The scala tympani and cochlear duct are separated by the basilar membrane. 2
How is the health of the cochlea measured?
The health of the cochlea is assessed by several tests. These types of hearing tests are sometimes referred to as tuning fork tests and are useful in detecting problems in the middle ear and inner ear.
Where are the membranes located in the cochlea?
the cochlea has a base (= screw head) and an apex (=point) two membranes extend from the spiral lamina to the lateral wall of the cochlea, dividing the bony cochlea into 3 compartments: scala vestibuli, scala tympani and scala media (= cochlear duct) the scalae wind around the modiolus ~3 times, defining apical, middle and basal turns
Which is part of the cochlea has a spiral lamina?
the bony SPIRAL LAMINA is represented by the threads of the screw the cochlea has a base (= screw head) and an apex (=point) two membranes extend from the spiral lamina to the lateral wall of the cochlea, dividing the bony cochlea into 3 compartments: scala vestibuli, scala tympani and scala media (= cochlear duct)
