Meeting Abstract 42.2 Tuesday, Jan. 5 Rotational flapping counter torque in insect flight CHENG, Bo*; DENG, Xinyan; Purdue University; Purdue University xdeng@purdue.edu We studied the aerodynamic torque generation of flapping wings during roll, pitch and yaw rotations of the stroke plane. The counter torques generated by the wing pair due to body rotations were previously termed as […]

How flying insects recover from in-flight stumbles
Meeting Abstract 42.5 Tuesday, Jan. 5 How flying insects recover from in-flight “stumbles” RISTROPH, L.*; BERGOU, A. J.; GUCKENHEIMER, J.; WANG, Z. J.; COHEN, I.; Cornell University; Cornell University; Cornell University; Cornell University; Cornell University ic64@cornell.edu Just as the Wright brothers implemented controls to achieve stable airplane flight, flying insects have evolved behavioral strategies that ensure recovery […]
How do bats accelerate
Meeting Abstract 42.6 Tuesday, Jan. 5 How do bats accelerate? RISKIN, DK; IRIARTE-DíAZ, J; MIDDLETON, K; BREUER, KS; SWARTZ, SM*; Brown University; The University of Chicago; California State University San Bernardino ; Brown University; Brown University sharon_swartz@brown.edu Analysis of the wing kinematics of bats flying at constant speed has provided understanding of mechanisms of thrust production. In […]
Fruit flies modulate passive wing pitching to generate in-flight turns
Meeting Abstract 42.1 Tuesday, Jan. 5 Fruit flies modulate passive wing pitching to generate in-flight turns BERGOU, Attila J*; RISTROPH, Leif; GUCKENHEIMER, John; COHEN, Itai; WANG, Z. Jane; Cornell University; Cornell University; Cornell University; Cornell University; Cornell University ajb78@cornell.edu To control their flight, insects must have mechanisms to modulate their wing kinematics. Exactly how insects control their […]
Non-uniform muscle strain and strain rate in the hollow muscular organs of soft-bodied animals
Meeting Abstract 42.6 Wednesday, Jan. 5 Non-uniform muscle strain and strain rate in the hollow muscular organs of soft-bodied animals THOMPSON, J.T.*; TAYLOR, K.R.; GENTILE, C.M.; Franklin & Marshall College; Franklin &; Marshall College; Franklin & Marshall College joseph.thompson@fandm.edu The cylindrical shape of soft-bodied invertebrates is well suited to functions in skeletal support and locomotion, but may […]
Myosin’s big radial force axial and radial tensions are similar in contracting muscle
Meeting Abstract 42.2 Wednesday, Jan. 5 Myosin’s big radial force: axial and radial tensions are similar in contracting muscle. WILLIAMS, CD*; REGNIER, M; DANIEL, TL; Univ. Washington, Seattle; Univ. Washington, Seattle; Univ. Washington, Seattle cdave@uw.edu During muscle contraction, cross-bridges attach to thin filaments and generate axial force. At the same time, two other critical mechanical events occur: […]
Myosin isoform fiber type in the tail of the Virginia opossum (Didelphis virginiana)
Meeting Abstract 42.3 Wednesday, Jan. 5 Myosin isoform fiber type in the tail of the Virginia opossum (Didelphis virginiana) HAZIMIHALIS, P.J.; BUTCHER, M.T.*; Youngstown State Univ. mtbutcher@ysu.edu Myosin heavy chain (MHC) isoforms are the primary determinants of muscle fiber contractile properties and muscle performance; therefore, the distribution of slow and fast fibers (i.e. MHC fiber types) reflect […]
Is titin a winding filament in active msucle A new twist on muscle contraction
Meeting Abstract 42.1 Wednesday, Jan. 5 Is titin a “winding filament” in active msucle? A new twist on muscle contraction MONROY, JA; UYENO, TA; NISHIKAWA, KC*; Northern Arizona University Kiisa.Nishikawa@nau.edu In striated muscle, titin contributes to passive tension, sarcomere integrity, and myofibrillar assembly. Previous studies suggest that titin plays a role in active muscle, but such a […]
Force-length properties, pinnation angle and mechanical advantage of the goat medial and lateral gastrocnemius in relation to in vivo contractile function and muscle models
Meeting Abstract 42.5 Wednesday, Jan. 5 Force-length properties, pinnation angle and mechanical advantage of the goat medial and lateral gastrocnemius in relation to in vivo contractile function and muscle models. DE BOEF MIARA, M.*; LEE, S.M.; WAKELING, J.M.; BIEWENER, A.A.; Harvard University, Cambridge, MA; Simon Fraser University, Burnaby, BC; Simon Fraser University, Burnaby, BC; Harvard University, Cambridge, […]
Complex interactions between length and force in the elastic behavior of active muscle
Meeting Abstract 42.4 Wednesday, Jan. 5 Complex interactions between length and force in the elastic behavior of active muscle. GILMORE, L.A.*; MONROY, J.A.; NISHIKAWA, K.C.; Northern Arizona University; Northern Arizona University; Northern Arizona University leslie.gilmore@nau.edu Both the active force produced by a muscle and the passive force due to stretch depend on the length of the muscle.
