The most primitive form of locomotion is ambulatory (walking). The ambulatory mammals are plantigrade in form and few modifications are noted in the metacarpals and metatarsals as the animals walk on the soles of their feet. Plantigrade mammals may also run on their toes to lengthen their stride and thus increase speed.
Mammal - Locomotion, Adaptations, Movement | Britannica
2024年11月27日 · Terrestrial mammals have a number of modes of progression. The primitive mammalian stock walked plantigrade—that is, with the digits, bones of the midfoot, and parts of the ankle and wrist in contact with the ground. The limbs of ambulatory mammals are typically mobile, capable of considerable rotation. Mammals modified for running are termed ...
I. In general, we can recognize several types of locomotory specializations in mammals: In addition to powered flight, we see: a. Saltatorial - Hopping b. Cursorial - Running c. Scansorial - Climbing d. Gliding e. Swimming Most groups are pretty generalized, but there are many specialists that do one of these particularly well. II.
Mammals: Locomotion, Sense Organ and Origin | Vertebrates
In larger mammals (exemplified by bears) the locomotion is ambulatory while in smaller forms (e.g., shrews, opossums, etc.) the locomotion tends toward the cursorial types. Human beings practice an ambulatory bipedal plantigrade type of locomotion.

2007年1月1日 · Ambulatory mammals have relatively mobile joints, the ability to pronate-supinate the manus, five digits (often with opposable hallux and pollex), and a plantigrade to semi-digitigrade...
ambulatory locomotion, operating through basic walking. In fossorial, or digging mammals, parts of the skeleton are optimized for “swimming” through the earth. The olecranon process, the bony upper part of the ulna, is elongated allowing for increased power when digging through the dirt. In contrast, cursorial or hoofed mammals, have
The mammals under this category walk on the entire foot and are typically five-toed. The metatarsals and metacarpals are not fused and are longer than the phalanges. The wrist and ankle bones permit movement in various planes. In larger mammals (exemplified by bears) the locomotion is ambulatory while in
Mammal Locomotion | Writing in Biology - UMass
2019年2月7日 · Most mammals use all four limbs to move and so are called quadrupedal. Animals that spend most of their time walking are called ambulatory, and are generally plantigrade, which means that they walk on the soles of their hands and feet. Animals that do a lot of running are called cursorial, and are either digitigrade or unguligrade. Digitigrade ...

2019年2月2日 · Adapting to diverse environments, mammals have evolved various foot postures that can be largely summarized into plantigrady (P; walking on the whole foot, e.g., mice, rats, squirrels, and humans), digitigrady (D; walking on toes, e.g., cats and dogs), and unguligrady (U; walking on hooved tiptoes, e.g., deer and horses) .
