The functional morphology of the avian flight muscle M. Coracobrachialis posterior.

摘要: The extensive range of movement the avian glenohumeral joint makes functional interpretation any muscle that crosses difficult. Multiple roles for M. coracobrachialis posterior (CBP), an architecturally complex lies deep to pectoralis, have been assigned on basis its anatomical position. mechanical properties, neuromotor pattern during flight and biochemical properties CBP in pigeons (Columba livia) were studied by situ length/active tension length/passive measurements, vivo electromyography histochemistry. action was directly through stimulation measurement humeral excursion non-reduced preparations.
