BIO348 Practical 2

Perilymph is the fluid found in the scala tympani of the cochlea.

The pigmented epithelium is a layer of cells in the retina that absorbs excess light and provides nutrients to the photoreceptors.

The vestibular membrane separates the scala vestibuli from the cochlear duct and plays a role in sound wave transmission.

Aldosterone is secreted by the zona glomerulosa, which is the outermost layer of the adrenal cortex.

Cochlea is NOT an auditory ossicle; the auditory ossicles are the malleus, incus, and stapes.

Endolymph is the fluid in the cochlear duct that helps in the transduction of sound waves into neural signals.

Auditory ossicles are three small bones in the middle ear (malleus, incus, stapes) that transmit sound vibrations from the eardrum to the inner ear.

The cochlea is responsible for converting sound vibrations into electrical signals that can be interpreted by the brain.

The basilar membrane plays a crucial role in the auditory system by supporting the organ of Corti, where hair cells convert sound vibrations into nerve impulses.

The tectorial membrane is a gelatinous structure in the cochlea that interacts with hair cells to facilitate the conversion of sound waves into electrical signals.
