Abstract:Elastic characteristics of the pig, sheep and cow vocal folds were investigated through a series of in vitro experiments. Sample strips of the vocal fold tissue were dissected from pig, sheep and cow vocal folds and mounted inside a saline-filled ergometer chamber that was maintained at 37°C ± 1°C. Sinusoidal elongation was applied on the samples to obtain the passive force measurements. Force and elongation data from the samples were recorded electronically with a dual-servo system (ergometer). Stress-Strain … Show more
“…39 No correlation between the time-dependent relaxation function and the strain level could be identified. Alipour et al 40 studied the slow-rate and stretch-release behavior of sheep, cow, and porcine vocal folds and compared with that of canine vocal folds. 38 The nonlinear response of porcine vocal folds was most similar to that of human vocal folds.…”

“…22 The Young's modulus for the superior folds of the porcine larynx was 22.0 kPa, whereas the sheep vocal folds were more pliable with a value of 17.6 kPa. The bovine samples had a higher modulus value (29.9 kPa) but were also longer and thicker.…”
“…Porcine VFs are the focus of this work owing to their structural similarity to human VFs [30][31][32][33][34][35] and the availability of tissue samples of varying age and gender. The LP of 38 pigs, varying in age from fetal to 2 + -year olds, were tested using the TWE.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
