Meeting Abstract 43.1 Jan. 6 Variable Gearing in Pinnate Muscles AZIZI, E.*; ROBERTS, T.J.; Brown University; Brown University manny_azizi@brown.edu Pinnate muscles are characterized by short fibers that attach at an angle relative to the muscle�s line of action. Recent studies have shown that as obliquely oriented muscle fibers shorten they also rotate. Fiber rotation during a muscle […]

SEX DIFFERENCES IN TELEOST CARDIAC BIOCHEMISTRY AND PHYSIOLOGY WHAT HAVE WE BEEN MISSING
Meeting Abstract 43.5 Jan. 6 SEX DIFFERENCES IN TELEOST CARDIAC BIOCHEMISTRY AND PHYSIOLOGY: WHAT HAVE WE BEEN MISSING? BATTIPROLU, Pavan K*; FARRAR, Richard S; HARMON, Kelli J; PIERSON, Nicholas S; RODNICK, Kenneth J; Idaho State University battpava@isu.edu Unlike numerous mammalian studies, studies of cardiac physiology and metabolism in fishes have paid little attention to sex or the […]
Protein Conservation in Spontaneous and Facultative Hibernators the White-tailed Prairie Dog (Cynomys leucurus) and the Black-tailed Prairie Dog (Cynomys ludovicianus)
Meeting Abstract 43.3 Jan. 6 Protein Conservation in Spontaneous and Facultative Hibernators: the White-tailed Prairie Dog (Cynomys leucurus) and the Black-tailed Prairie Dog (Cynomys ludovicianus) COTTON, C.J.; University of Wyoming, Laramie ccotton@uwyo.edu White-tailed prairie dogs are spontaneous hibernators that undergo regular, low temperature torpor bouts throughout the winter, while black-tailed prairie dogs are facultative hibernators that utilize […]
The versatile mechanical function of two proximal hindlimb muscles in running turkeys
Meeting Abstract 42.2 Jan. 6 The versatile mechanical function of two proximal hindlimb muscles in running turkeys ROBERTS, T.J.*; HIGGINSON, B.K.; Brown University, Providence, RI; Oregon State University, Corvallis Thomas_Roberts@Brown.edu The muscles that power running must be remarkably flexible in their mechanical function. For example, the muscular system performs almost no net mechanical work during level running, […]
Ontogeny of Muscle Fiber Type Distribution in Climbing Hawaiian Gobioid Fishes Muscle and locomotor correlation
Meeting Abstract 42.4 Jan. 6 Ontogeny of Muscle Fiber Type Distribution in Climbing Hawaiian Gobioid Fishes: Muscle and locomotor correlation CEDIEL, R*; SCHOENFUSS, H; BLOB, R; SHRANK, G; St.Cloud State; St.Cloud State; Clemson; St.Cloud State cero0201@stcloudstate.edu Three species of Hawaiian amphidromous gobies are remarkable in their ability to climb waterfalls several hundred meters tall. Juveniles of Lentipes […]
Muscle Function in a Complex Muscle During Legged Locomotion
Meeting Abstract 42.3 Jan. 6 Muscle Function in a Complex Muscle During Legged Locomotion CARR, J.A.*; MARSH, R.L.; Northeastern University; Northeastern University carr.je@neu.edu 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, but this muscle […]
Function of uniarticular and biarticular heads of the triceps during jumping and landing in goats
Meeting Abstract 42.1 Jan. 6 Function of uniarticular and biarticular heads of the triceps during jumping and landing in goats. CARROLL, A. M.*; BIEWENER, A. A.; Concord Field Station, Harvard University; Concord Field Station, Harvard University acarroll@oeb.harvard.edu Muscle systems in the limbs of tetrapods are often organized into synergistic uni- and bi-articular regions. To understand how these […]
Elastic properties of muscle during active shortening
Meeting Abstract 42.6 Jan. 6 Elastic properties of muscle during active shortening MONROY, J.A.*; GILMORE, L.A.; KREBS, L.; LAPPIN, A.K.; LINDSTEDT, S.L.; PIEROTTI, D.J.; NISHIKAWA, K.C.; Northern Arizona University Jenna.Monroy@nau.edu Recent work demonstrates that muscles themselves store elastic energy during isometric tetanus. When the force is reduced rapidly, muscles recoil elastically. Elastic recoil of muscle contributes to […]
Anatomy and Histochemistry of Golden Eagle Flight Muscles
Meeting Abstract 42.5 Jan. 6 Anatomy and Histochemistry of Golden Eagle Flight Muscles MEYERS, R.A.*; MCFARLAND, J.C.; Weber State University, Ogden, UT; Weber State University, Ogden, UT rmeyers@weber.edu Previous research in our laboratory and elsewhere has show that soaring birds such as albatrosses, vultures and pelicans possess a slow-contracting deep layer to the pectoralis that is presumed […]
