Meeting Abstract 6.4  Thursday, Jan. 3  Morphological and mechanical asymmetry in a biological gyroscope. GEIGER, M.J.*; FOX, J.L.; MYHRVOLD, C.A.; DANIEL, T.L.; Univ.Washington, Seattle; Univ.Washington, Seattle; Pinceton Univ., Princeton; Univ.Washington, Seattle danielt@u.washington.edu Flies rely on mechanosensory input from reduced hindwings known as halteres to perform complex maneuvers. We are interested in how the mechanical properties of such […]

Meeting Abstract 5.7  Thursday, Jan. 3  The long and winding road: diffusion limitation in skeletal muscle KINSEY, S.T.*; HARDY, K.M.; LOCKE, B.R.; Univ. of North Carolina Wilmington; Univ. of North Carolina Wilmington; Florida State University kinseys@uncw.edu A fundamental principle of physiology is that cells are small in order to minimize diffusion distances for O2 and intracellular metabolites. […]

Meeting Abstract 5.4  Thursday, Jan. 3  Spring properties of muscle during active shortening and lengthening MONROY, JA*; HOKANSON, J; NISHIKAWA, KC; Northern Arizona University; SUNY Cortland jenna.monroy@nau.edu When its load is reduced, an active muscle will recoil elastically to a shorter length. When its load increases, an active muscle will lengthen. In this study, we describe and […]

Meeting Abstract 5.1  Thursday, Jan. 3  Slow-twitch oxidative muscle development in yellowfin tuna, Thunnus albacres DICKSON, Juleen*; DICKSON, Kathryn; California State University Fullerton; California State University Fullerton jdickson@fullerton.edu The purpose of this study was to describe the development of slow-twitch, oxidative myotomal muscle (SM) in a size series of juvenile yellowfin tuna, Thunnus albacares. The SM powers […]

Meeting Abstract 5.10  Thursday, Jan. 3  Parvalbumin’s ability to bind calcium in the face of varying environmental salinity in the Atlantic stingray, Dasyatis sabina HEFFRON, Jennifer K.*; MOERLAND, Timothy S.; Florida State University; Florida State University heffron@bio.fsu.edu The Atlantic stingray, Dasyatis sabina, is a euryhaline species that migrates back and forth between freshwater and the marine environment. […]

Meeting Abstract 5.3  Thursday, Jan. 3  Neuromuscular control of mechanical power output in hummingbirds II: Measurements of muscle work and power. WELCH, KC*; JOSEPHSON, RK; ALTSHULER, DL; Univ. of California, Riverside; Univ. of California, Irvine; Univ. of California, Riverside kenwelch@ucr.edu Hummingbird flight muscles are predicted to have the highest mass-specific mechanical power requirements of any vertebrate muscle. […]

Meeting Abstract 5.5  Thursday, Jan. 3  More boing for your buck: spring properties of muscle at and beyond optimal length. GILMORE, L.A.*; MONROY, J.A.; HOKANSON, J.; NISHIKAWA, K.C.; Northern Arizona University; Northern Arizona University; SUNY, Cortland; Northern Arizona University Leslie.Gilmore@nau.edu A muscle produces maximal force when activated at its optimal length. If the muscle is rapidly unloaded […]

Meeting Abstract 5.8  Thursday, Jan. 3  Intracellular diffusion constraints may influence organelle distribution in skeletal muscle HARDY, KM*; DILLAMAN, RM; KINSEY, ST; University of North Carolina Wilmington; University of North Carolina Wilmington; University of North Carolina Wilmington kmh6265@uncw.edu Different organelles require different conditions to function inside of a cell. Mitochondria depend on oxygen flux, and produce small, […]
