Locomotion - Saltation: The locomotor pattern of saltation (hopping) is confined mainly to kangaroos, anurans (tailless amphibians), rabbits, and some groups of rodents in the vertebrates and to a number of insect families in the arthropods. All saltatory animals have hind legs that are approximately twice as long as the anteriormost legs.
In axial locomotion, which includes the hydraulic ramjet method of ejecting water (e.g., squid), production of a body wave (eel), or the contract–anchor–extend method (leech), the body shape is modified, and the interaction of the entire body with the surrounding environment provides the propulsive force. In appendicular locomotion, special body appendages interact with the environment to produce the propulsive force.
The skip is perhaps the simplest form of standing locomotion involving the cross-crawl pattern shown below. In the cross-crawl pattern, the left arm coordinates with the right leg and the right arm coordinates with the left leg. The primary difference between the crawl and the skip is simply that in one you are on your stomach whereas in the ...
The stretch reflex is caused by a stretch in the muscle spindle. When the stretch impulse is received a rapid sequence of events follows. The motor neuron is activated and the stretched muscles, and its supporting muscles, are contracted while its antagonist muscles are inhibited.
Animal locomotion, in ethology, is any of a variety of movements or methods that animals use to move from one place to another. Some modes of locomotion are (initially) self-propelled, e.g., running, swimming, jumping, flying, hopping, soaring and gliding.
