Abstract
The transduction of sound into nerve impulses requires an ionic environment that depends on a variety of ion transport processes in epithelial and endothelial cells of the cochlea. Specific ion transport functions occur in specific cell types that coordinate the production and maintenance of endolymph, which is the fluid in the lumen of the cochlear duct that supports the sensory transduction process. The critical nature of these ion transport processes is underscored by observations of hearing loss when ion transport mechanisms malfunction as a result of mutations, drug exposure, or hormonal imbalance. This chapter describes our basic understanding of salient ion transport processes and their regulation by hormones and other regulatory pathways.
