Elasticity of canine vocal fold tissue.
Stress-strain curves were obtained from vocalis muscle tissue that was kept viable in an aerated Krebs-Ringer solution after excision of the larynx from live dogs. Results are compared to similar curves obtained from dead tissue and suggest that vocal fold elasticity depends on the level of strain, the elapsed time after elongation, the condition of the tissue, and the choice of rest length for strain computation. Tables of Young's moduli for various conditions are given.
