Inner ear hair cells. Coloured scanning electron micrograph (SEM) of sensory hair cells from the inner ear. These cells are surrounded by a fluid called endolymph. As sound enters the ear it causes waves to form in the endolymph, which in turn cause the hairs to move. The movement is converted to an electrical signal that is passed on to the brain. Each crescent-shaped arrangement of hairs lies atop a single cell.
Crystal field theory is a model that describes how the electrons fill in the outer energy levels or orbital in the presence of ligands. Crystal field theory also describes the strength of the bond, but it cannot attempt to describe the actual bonding.
