This hypothesis has been studied further by examining the oxygen consumption rates in the snake during different modes of locomotion: lateral undulation, concertina, [13] and sidewinding. [14] The net cost of transport (NCT), which indicates the amount of energy required to move a unit of mass a given distance, for a snake moving with a lateral ...
Rectilinear locomotion relies upon two opposing muscles, the costocutaneous inferior and superior, which are present on every rib and connect the ribs to the skin. [5] [6] Although it was originally believed that the ribs moved in a "walking" pattern during rectilinear movement, studies have shown that the ribs themselves do not move, only the muscles and the skin move to produce forward ...
Sidewinding is a type of locomotion unique to snakes, used to move across loose or slippery substrates. It is most often used by the Saharan horned viper, Cerastes cerastes , the Mojave sidewinder rattlesnake , Crotalus cerastes , and the Namib desert sidewinding adder, Bitis peringueyi , to move across loose desert sands, and also by ...
Concertina movement is the method by which a snake or other organism anchors itself with sections of itself and pulls or pushes with other sections to move in the direction it wants to go. To spring forward a snake may require a rough surface to thrust back against. [1] [2] It is named after the concertina musical instrument. [citation needed]
Most often employed by colubroid snakes (colubrids, elapids, and vipers) when the snake must move in an environment that lacks irregularities to push against (rendering lateral undulation impossible), such as a slick mud flat, or a sand dune, sidewinding is a modified form of lateral undulation in which all of the body segments oriented in one ...

The cells in the human body are not outnumbered 10 to 1 by microorganisms. The 10 to 1 ratio was an estimate made in 1972; current estimates put the ratio at either 3 to 1 or 1.3 to 1. [299] The total length of capillaries in the human body is not 100,000 km.
