We already know that, in the latter, the metacarpals and the digits are equally reduced in number; the same is the case for the metatarsals and the toes.
Their metacarpal bones are four in number, and are all distinct, in which respect they differ from the peccaries, in which the central metacarpals and metatarsals are fused into a solid bone.
One, several, or all of the metatarsals may be separated from the distal row of tarsal bones--the usual cause being a fall from a horse, the foot being fixed in the stirrup.
The use of the Röntgen rays has shown, however, that certain painful conditions in the foot following comparatively slight injuries, such as kicking a stone, are due to a fracture of one of the metatarsals or phalanges.
It may be excited by pressing the heads of the metatarsals together or by grasping the fourth metatarso-phalangeal joint between the finger and thumb.
When the head of one of the metatarsals is displaced, it may be removed through a dorsal incision running parallel with the tendon of the long extensor.
Fractures of the metatarsalsand phalanges# usually result from direct violence, such as a crush of the foot, in which the soft parts are severely damaged.
In the Penguins the metatarsalsare separate, and in many birds larger or smaller gaps exist between the fused metatarsals.
The second, third and fourth metatarsalsin 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.
D) in which the third toe is greatly developed, while the second and fourth are reduced to slender metatarsals attached to the proximal half of the third metatarsal.
At the distal end of the bone the three metatarsals diverge from one another and each bears a prominent convex pulley-like surface.
All the tarsal bones are small and somewhat polygonal, and are connected with one another, and with the tibia and fibula on the one hand, and with the metatarsals on the other by a thin layer of cartilage.
The metatarsals are ankylosed together, and the pes has four digits.
The metatarsals are elongated and the feet digitigrade.
The lines of junction between the several metatarsals are marked along the shaft by slight ridges.
In the Jerboa (Dipus) a curious condition of the pes is met with, as it consists of three very long metatarsals fused together and bearing three short toes, each formed of three phalanges.
The tarsals are ankylosed respectively to the tibia and metatarsals as in other birds.
In the Tragulina the cuboid, navicular, and two outer cuneiforms are united forming a single bone; all fourmetatarsals are complete and the two middle ones are united.
The postaxial of these is the largest, it articulates with the second and thirdmetatarsals and is probably homologous with tarsalia 2 and 3 fused.
In almost every case the phalanges and first metatarsal have epiphyses only on their proximal ends, while the remaining four metatarsals have epiphyses only on their distal ends.
In the Suina four toes are developed, and though in the Peccaries the third and fourth metatarsals are united, they are all distinct in most members of the group, as are all the tarsal bones.
In the Tylopoda and Anoplotherium commune only the third and fourth digits are developed, their metatarsals are free distally, but are elsewhere united.
Of the metatarsals the fifth occurs as an embryonic vestige near the joint; the first is reduced to its distal portion, and is, with the hallux, shoved on to the inner and posterior side of the foot, at least in the majority of birds.
The short feet of the penguins are quite plantigrade, in adaptation to which habit the metatarsals lie in one plane and are incompletely co-ossified, thus presenting a pseudo-primitive condition.
The slender toes of many birds, and even the two toes of the ostrich, may be thought to give less adequate support for those animals than the metatarsals and digits of Pterodactyles.
The bones of the instep, instead of being held together firmly as in the Lias genera, diverge from each other, widening out, though it often happens that four of the five metatarsals differ but little in length.
In all there are but two functional digits on the feet, and the metacarpals and metatarsals of these are fused.
The three metatarsals are closely pressed together, and the foot is as it were on the way towards the highly-modified foot of the Jerboa.
The three metatarsals are elongated almost like those of a bird, and are ankylosed together.
The metacarpals and metatarsalshave coalesced to form the cannon bones, though a rudiment of one metacarpal seems to remain.
The carpals, tarsals, metacarpals, andmetatarsals are all free.
The lateral digits are larger than in Phenacodus, and the metatarsals and the phalanges are slightly curved, which is again a Creodont character as compared to the perfectly straight corresponding bones of Phenacodus.
Thus the metacarpals and metatarsals were not fused to form a cannon bone, and the two lateral digits were represented by splint rudiments of metacarpals and metatarsals.
The fused metacarpals and metatarsals diverge somewhat at their distal ends.
As a general rule the third and fourth metacarpals and metatarsals become united to form a cannon bone.
Series of metacarpals and metatarsals of Camelidae, to show secular and progressive increase in size.
The {285} metatarsals are free, but with a tendency to fusion; the lateral toes are only represented at the upper extremity.
The metacarpals and metatarsalsare generally distinct (fig.
The middle metacarpals and metatarsals generally confluent, the outer ones (second and fifth) slender but complete, i.
Third and fourth metacarpals and metatarsals confluent into cannon-bones (fig.
Third and fourth metacarpals and metatarsals (which are alone present) fused into cannon-bones for the greater part of their length, but diverging inferiorly (fig.
There is no fracture of the bones, although a shrapnel ball has passed transversely through the foot, striking the heads of the second and third metatarsals with only slight injury and leaving a few metal particles at points of contact.
The fragments of metal lying near the fourth and fifth metatarsals lie either in the same relation or on the plantar side of the metatarsus.
Having fixed the position of the articulations of the first and fifth metatarsals with the tarsus, the operator unites them by a curved incision across the dorsum of the foot, with its convexity downwards.
The plantar cicatrix is almost a fatal objection to a plan of removing the first and fifth toes and their metatarsals which has much otherwise in rapidity and elegance to recommend it.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "metatarsals" in a variety of sentences. We hope that you will now be able to make sentences using this word.
