dc.description.abstract "The present paper presents the results of a study on the functional morphology of hind-limb locomotion in the domestic pigeon, Columba livia. The structure and function of the hind-limb joints is discussed first. The major morphological features of the joint are examined using techniques of microscopic and gross anatomy, and these results are correlated with the kinds and amounts of movement permitted at each joint. Next, a detailed description of the hind-limb muscles is presented. Included in the descriptions are data on origins and insertions, the arrangement of the fibers in relation to aponeuroses of origin and insertion, the relative length of the fibers, the angle of pinnation, and information about the histological composition twitch (fibrillenstruktur) and tonus (felderstruktur) fibers within the muscle. The data in the section on muscle description are then used in conjunction with some basic principles of muscle physiology to arrive at more well-founded conclusions as to the functions of the different muscles. A high-speed motion picture analysis of hind-limb locomotion in the pigeon is then given. Three different gaits (moderate walk, slow walk, and a run) are studied and compared with respect to angular displacements and angular velocities. The important aspects of landing are briefly considered. Finally, the results of the functional analysis of the muscles are combined with those of the motion picture analysis to enable the construction of an activity sequence of the muscles during a walk. Information such as when muscles are active during a step and the kinds of motion observed is considered. Certain features of one-joint and multi-joint muscles and of vertebrate joint structure and function are discussed"--P. 265. en_US

Files in this item

This item appears in the following Collection(s)

  • Bulletin of the American Museum of Natural History
    The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates , published short papers describing new forms.
