The width of a proximal carpal rarely exceeds two inches, and that of a distal carpal is about an inch and three-quarters.
One specimen shows by an indication of sutures the original division of the distalcarpal into three bones; and the separated constituent bones are very rarely met with.
In all the Cretaceous genera the carpal bones of each row are blended into a single bone, so that two bones are superimposed, which may be termed the proximal and distal carpals.
In the German fossils the pteroid articulated with a separate carpal or metacarpal bone, placed on the side of the arm adjacent to the radius, and the radius is always more inward than the ulna.
Rosenberg, of Dorpat, showed that there is in the bird a proximalcarpal formed of two elements, and a distal carpal also formed of two elements.
At the carpal end it is oblong and truncated, with a short middle process, which may have extended into the pit in the base of the carpal bone; while the distal terminal end is rounded exactly like a pulley.
There is no indication of division of the proximal carpal in these genera into constituent bones.
Therefore the two constituents of the distalcarpal in the bird which blends in the mature animal with the metacarpus, forming the rounded pulley joint, may correspond with two of the three bones in the Cretaceous Pterodactyle Ornithocheirus.
It involves the interpretation of what has been termed the lateral carpalas the first metacarpal bone, which would be as short as that of a bird, but turned in the opposite direction backward.
Humerus with a perforation on the inner side of the lower end; a very large extra radial carpal bone.
The regular number of the toes or tarsal joints is five, so that they correspond to our digital phalanges, to the metacarpal, and the anterior carpal bone.
If what has been called the metacarpal bone of the thumb be numbered, which it must, as a digital articulation or phalanx, every finger has thus one carpal bone, and each bone of the fore arm also one.
When the infection spreads into the common flexor sheath under the transverse carpal (anterior annular) ligament, it is not uncommon for the intercarpal and wrist joints to become implicated.
If pus has spread under the transverse carpal ligament, the incision must be made above the wrist.
Below the carpal and tarsal joints, the fore and hind limbs correspond almost exactly in structure as well as function.
This results from the fact that the tendons of the flexors, too firmly bound by the carpal sheath, gradually separate as they pass from the metacarpus, going to join the fetlock; hence the obliquity pointed out above.
The carpal bones are seven in number--four in the superior row, and three in the inferior.
Indeed, in this animal the groove in question is found on the external surface of the carpal extremity of the radius.
It is reinforced at the lower end of the radius by the superior carpal ligament, passes through the carpal and metacarpo-phalangeal sheaths, and, arriving behind the fetlock, forms a ring for the passage of the flexor perforans.
These portions are continued by a common tendon which enters the carpal sheath with the tendon of the perforatus, and continues with it through the synovial sheath of the metacarpo-phalangeal region.
The two rows of carpal bones may be separated from one another, or any one of the individual bones may be displaced.
In a considerable proportion of cases it is impacted, and not infrequently the lower fragment is comminuted, the fracture extending into the radio-carpal joint.
Sometimes the carpal bones are so soft that the needle can be made to penetrate them in different directions.
Dorsal Dislocation of Wrist at Radio-carpal Articulation, in a man, æt.
In the majority of cases the styloid process of the ulna is torn off by traction exerted through the medial ulno-carpal (internal lateral) ligament, and in a considerable proportion there is also a fracture of one of the carpal bones.
A fracture of the lower end of the radius with forward displacement of the carpal fragment, was first described by R.
An interesting feature, sometimes met with in arthritis deformans, consists in eburnation of the articular surfaces of the carpal bones, although the range of movement is almost nil.
Scaphoid bone (a) One of the carpal bones, which articulates with the radius; the radiale.
In the horse and allied animals, the carpal joint, corresponding to the wrist in man.
Longest facial vibrissae brownish, like dark color of head and extending beyond ear; carpal vibrissae mostly color of underparts and extending to apical pad of fifth digit; hairiness of foot-soles slightly more than shown in figure 20.
Longest facial vibrissae dark brown or white and extending beyond ear; carpal vibrissae same color as underparts and extending to apical pad of fifth digit; hairiness of foot-soles (in summer pelage) as shown in figure 20.
Longest facial vibrissae black and reaching beyond ear; carpal vibrissae same color as underparts and extending to apical pad of fifth digit; hairiness of foot-soles as shown in figure 20.
The maximum length of facial and carpal vibrissae is attained in M.
Longest facial vibrissae black and extending beyond ear; carpal vibrissae same color as upper parts and extending to apical pad of fifth digit; hairiness of foot-soles as shown in figure 20.
The carpalplate itself becomes segmented from the radius and ulna, and divided up into the carpal bones.
The centrale and intermedium are the middle and proximal products of the segmentation of the ulnar column of the primitive carpus, the distal second carpal being common both to this column and to the radial column.
In the further growth the third and fourth digits, and in the foot the fifth digit also, gradually sprout out in succession from the ulnar side of the continuous carpal plate.
In this way a continuous carpal plate of cartilage is established, which is on the one hand continuous with the cartilage of the two metacarpals, and on the other with the radius and ulna.
The original radial column is divided into three elements, a proximal the radiale, a middle element the first carpal, and a distal the second carpal already spoken of.
The carpal bones of the Artiodactyla alternate in their articulation; the primitive state of affairs[180] is not retained even in the earliest types.
An accessory carpal ossicle in front of the pisiform, which is not seen in the figure.
Radial and ulnar carpal bones; with the three digits I.
The ulna is curved and rather stout; it articulates with both carpal bones; the cubital quills often cause rugosities on its dorsal surface.
The wing is at all ages striped with two greyish-white bands that run in the direction of the carpal joint.
The fifth bone of the same character is articulated in a much more free and moveable manner than the others, with its carpal bone, and forms the base of the thumb.
The bony basis may be the humerus, from which diverge radius and ulna, the carpal bones being formed of the intervening cartilage.
The accessory carpalbone (trapezium) is said to be fractured at times without being subjected to blows or like injuries, but this is exceptional.
Inflammation and Contraction of the Carpal Flexors.
Recognition of fracture of any other single carpal bone must be done by detecting crepitation unless it be a compound fracture, whereupon probing is of aid in establishing a diagnosis.
The accessory carpalbone may be readily manipulated and when fractured, its parts are more or less displaced.
In thecarpal region, the flexors of the phalanges are contained together in the carpal sheath, and this is the principal theca in the carpal region.
Radial artery turning round the carpal end of the metacarpal bone of the thumb.
Is one of the front legs bent forward at the carpal joint?
In skinning, disjoint the leg bones at the carpal joint,[10] which leaves only the bones of the foot attached to the skin.
Total length; distance from angle of wing at the carpal joint to the eye; distance from the end of the closed wing to the tip of the tail; distance from the base of the middle toe to the carpal joint of the wing.
Lift up the wing and put two or three thicknesses of wet cloth, or else thoroughly wet cotton batting, around the carpal joints, and also between the wing and the body.
Carpal bones: Middle carpal bone not extending farther proximally than those on either side of it.
Radius: Broader proximally and rounded at distal end, where it extends outward beyond the carpal bones.
The pectoral fins are small, and have been carefully preserved, with the various carpal and phalangeal bones kept together by their natural ligaments.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "carpal" in a variety of sentences. We hope that you will now be able to make sentences using this word.
