Axial muscle function during lizard locomotion
It was recently reported that the epaxial muscles of a lizard, Varanus salvator, function to stabilize the trunk during locomotion, and it was suggested that this stabilizing role may be a shared derived feature of amniotes. This result was unexpected because it had previously been assumed that the epaxial muscles of lizards function to produce lateral bending during locomotion and that only in...
متن کاملTwisting and bending: the functional role of salamander lateral hypaxial musculature during locomotion.
The function of the lateral hypaxial muscles during locomotion in tetrapods is controversial. Currently, there are two hypotheses of lateral hypaxial muscle function. The first, supported by electromyographic (EMG) data from a lizard (Iguana iguana) and a salamander (Dicamptodon ensatus), suggests that hypaxial muscles function to bend the body during swimming and to resist long-axis torsion du...
متن کاملRelaxation phenomenon in lumbar trunk muscles during lateral bending.
This paper reports myoelectric activity measurements in the lumbar trunk muscles when subjects performed tasks involving various degrees of lateral bending. Biomechanical model analyses were made to estimate the tensions in the lumbar trunk muscles required to perform those tasks. The tensions and the activity measurements were compared to see if a muscle relaxation phenomenon occurred. A relax...
متن کاملMuscle Recruitment during Terrestrial Locomotion: How Speed and Temperature Affect Fibre Type Use in a Lizard
Synchronized electromyography and cinematography were used to study the activity of the red and white regions of the iliofibularis muscle in savannah monitor lizards, Varanus exanthematicus (Bosc), during locomotion. Analysis of variance on results from four individuals moving at speeds of up to 1.5 km h" at two body temperatures (25 and 35 °C) revealed that all kinematic variables were signifi...
