Legged locomotion is the dominant form of terrestrial locomotion, the movement on land. The motion of limbs is quantified by the kinematics of the limb itself (intralimb kinematics) and the coordination between limbs (interlimb kinematics). [1] [2] Figure 1. Classifying stance and swing transitions of the front right (red) and left (blue) legs ...
Rather, large numbers of "nervous centres" cooperate in order to make a whole movement possible. Nervous impulses from different parts of the CNS may converge on the periphery in combination to produce a movement; however, there is great difficulty for scientists in understanding and coordinating the facts linking impulses to a movement.

Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).
A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of certain flagella, which work like corkscrews).
The relative roles of form cues compared to motion cues in the process of perceiving biological motion is unclear. Previous research has not untangled the circumstances under which local motion cues are needed or only additive. This model looks at how form-only cues can replicate psychophysical results of biological motion perception.
Type of protist Movement mechanism Description Example Other examples Motile Flagellates: A flagellum (Latin for whip) is a lash-like appendage that protrudes from the cell body of some protists (as well as some bacteria).
Movement on appendages is the most common form of terrestrial locomotion, it is the basic form of locomotion of two major groups with many terrestrial members, the vertebrates and the arthropods. Important aspects of legged locomotion are posture (the way the body is supported by the legs), the number of legs, and the functional structure of ...
An example of a point light display of an American Sign Language sentence. The biological motions of the signer can be observed through the motions of white dots, as they sign a sentence. Biological motion is motion that comes from actions of a biological organism.
