Gibbs-Helmholtz equation - see under GibbsHelmholtz axis ligament - a ligament forming the axis about which the malleus rotates. Synonym(s): axis ligament of malleusHelmholtz coilHelmholtz energy - energy equivalent to the internal energy minus the entropy contribution.Helmholtz keratometerHelmholtz ophthalmoscopeHelmholtz theory of accommodation - the ciliary muscle relaxes for near vision and allows the anterior aspect of the lens to become more convex.Helmholtz theory of color vision - Synonym(s): Young-Helmholtz theory of color visionHelmholtz theory of hearing - that the basilar membrane of the cochlea acts as a resonating structure, recording low tones from its apical turns and high tones from its basal turns. Synonym(s): resonance theory of hearingHelmholtz-Gibbs theory - Synonym(s): Gibbs-Helmholtz equationYoung-Helmholtz theory of color vision - see under Young, Thomas
