The more typical members of the group were digitigrade animals, recalling in general build the llamas and horses; they have small brains, and a facet on the calcaneum for the fibula.
In the latter also the fibula, which is anchylosed to the end of the tibia, articulates with the calcaneum or heel-bone, which is not the case with the simple-toothed rodents.
In the case cited by Hoare the animal evinced great pain and uneasiness; the hock was unduly flexed; the calcaneum was displaced forward; and marked crepitation was present.
The hock is said to be curbed when the normal appearance, viewed from the side, is that of bulging posteriorly at any point between the summit of the calcaneumand the upper third of the metatarsus.
A portion of the body of the calcaneum was protruding through the perforated skin.
The calcaneum has a large backwardly-projecting process.
The calcaneum does not articulate with the fibula, except in Macrauchenia.
The astragalus is very flat, and the tarsals interlock to a slight extent, the cuboid articulating with both calcaneum and astragalus.
In the proximal row of tarsal elements there are only two bones, the calcaneum and astragalus.
The calcaneum articulates with the lower end of the fibula when that bone is fully developed.
The calcaneum in Crocodiles is drawn out into a long process forming a heel in a manner almost unique among Sauropsida.
The calcaneum resembles that of Artiodactyles in having a small facet for articulation with the fibula.
The calcaneum articulates with the lower end of the fibula if that bone is fully developed.
The calcaneum has a large facet for articulation with the fibula, as in Artiodactyla.
The posterior limb is greatly elongated and is pentedactylate; the tibia and fibula are fused, while the calcaneum and astragalus are greatly elongated, and it is largely owing to them that the length of the limb is so great.
The second, third and fourth metatarsals in this form are nearly two-thirds as long as the femur, and the calcaneum is drawn out into a heel much as it is in most mammals.
In some of the Lemuroidea, especially Tarsius, the tarsus is curiously modified by the elongation of the calcaneum and navicular.
The calcaneum does not articulate with the fibula.
The calcaneum articulates with the fibula as in Artiodactyles.
The calcaneum is sometimes produced into a long slender process which helps to support the membrane between the leg and the tail.
The fibula articulates with both the calcaneum and the astragalus, which is not the case with Phenacodus.
In the hind-foot the calcaneum has an articular facet for the fibula, which is not characteristic of the Perissodactyla.
A very marked skeletal character distinguishes this sub-family from other Lemuridae, and allies them to Tarsius, that is the lengthening of the calcaneum and naviculare in the ankle.
The astragalus and the calcaneum differ slightly from those of ruminants.
The bones of the tarsus are six in number: the calcaneum and astragalus form the upper row; the cuboid, scaphoid, and two cuneiforms form the lower (Fig.
We have already mentioned that the scaphoid and the cuboid are ankylosed; they form by their union an irregular bone, on which the astragalus and calcaneum are supported.
The calcaneum is long and narrow; it is longer than that of the horse; it is on the anterior and external part that the bone (coronoid tarsal bone) which represents the inferior extremity of the fibula is situated.
The length of the calcaneum still further exaggerates this difference, and, as in the animals with which we shall occupy ourselves later on, the projection which this bone forms is distinctly higher than that which is produced by the pisiform.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "calcaneum" in a variety of sentences. We hope that you will now be able to make sentences using this word.
