Meeting Abstract 98.1 Wednesday, Jan. 7 Muscle Function in a Complex Muscle During Terrestrial and Aquatic Locomotion CARR, J.A.*; MARSH, R.L.; Northeastern University; Northeastern University carr.je@gmail.com Understanding the mechanical function of muscles with extensive origins and insertions is challenging. The Iliotibialis lateralis pars postacetabularis (ILPO) is one of the largest muscles in the hindlimb of cursorial birds, […]

Force transmission versus speed amplification in a four bar linkage mechanism counterintuitive results in the mantis shrimps strike
Meeting Abstract 98.11 Wednesday, Jan. 7 Force transmission versus speed amplification in a four bar linkage mechanism: counterintuitive results in the mantis shrimps strike CLAVERIE, Thomas*; PATEK, Sheila N.; Univ. of California, Berkeley; Univ. of California, Berkeley tclaverie@berkeley.edu Four bar linkages are simple mechanical systems that can amplify or reduce rotation. Most biological four bar systems have […]
Flexor vs extensor activity during jumping and swimming in Rana pipiens
Meeting Abstract 98.8 Wednesday, Jan. 7 Flexor vs. extensor activity during jumping and swimming in Rana pipiens NOYES, N*; GILLIS, GB; Mount Holyoke College; Mount Holyoke College ggillis@mtholyoke.edu Despite widespread study of jumping and swimming in anurans, little is known about the functional roles of limb flexor muscles in these animals. Work in toads demonstrates some overlap […]
Fatigue fiddles with fowl function Altered muscle function during locomotion
Meeting Abstract 98.4 Wednesday, Jan. 7 Fatigue fiddles with fowl function: Altered muscle function during locomotion HIGHAM, T.E.*; BIEWENER, A.A.; Clemson University; Harvard University thigham@clemson.edu For over a century, scientists have been captivated and challenged by the mechanisms and effects of muscle fatigue, which is defined as a reduction in muscle force as a consequence of exercise. […]

MARSH, Richard L.*; HITCHCOCK, Amanda C.; TRUONG, Rosemary; PROPERT, Matthew W.G.; Northeastern University; Northeastern University; Northeastern University; Northeastern University r.marsh@neu.edu We combined measures of joint moments, joint angles, and instantaneous effective moment arms at the ankle and tarsometatarsal-phalangeal joints with […]
Adaptations of the perivertebral musculature to different locomotor behaviours in lizards
Meeting Abstract 98.3 Wednesday, Jan. 7 Adaptations of the perivertebral musculature to different locomotor behaviours in lizards. MORITZ, S.; Friedrich-Schiller-Universitaet Jena sabine.moritz@uni-jena.de Although the trunk and its associated musculature play an important role during locomotion in lizards, studies on the locomotor apparatus are biased towards legs and only very few studies on the axial musculature exist. One […]
Waiting to Exhale Tracheal Air-filling in Embryos of Manduca sexta
Meeting Abstract 97.5 Wednesday, Jan. 7 Waiting to Exhale: Tracheal Air-filling in Embryos of Manduca sexta SPRAGUE, J. C.*; SMITH, J. N.; WOODS, H. A.; Univ. Montana; Univ. Montana; Univ. Montana jonathan1.sprague@umontana.edu Insects exchange gases via branching tubes called trachea, which are air filled in larvae, pupae, and adults. In embryos, by contrast, tracheae are liquid filled […]
