The terminal or ungual phalanges of the digits are commonly specially modified to support nails, claws, or hoofs.
In the Manidae the scaphoid and lunar are united; five digits are present, the third and fourth being very large, and all being terminated by deeply cleft ungual phalanges.
In the Frugivorous bats the second digit is clawed as well as the pollex, in other bats this claw is always absent, and so is often the ungual phalanx, the middle phalanx then tapering gradually to its termination.
In the Tillodontia the manus is plantigrade and has pointed ungual phalanges, in this respect approaching the Carnivora.
In Pinnipedia the manus is large and flat and the digits are terminated by ungual phalanges which are blunt (sea lions and walrus), or slightly curved and pointed (seals).
In Chalicotherium and Agriochoerus the pes has the same abnormal characters as the manus, the digits being clawed and the ungual phalanges in Chalicotherium deeply cleft.
The digits of both manus and pes are terminated by pointed ungualphalanges which must have borne claws.
The ungual phalanges are large and pointed, and in forms like the Cats, whose claws are retractile, they can be folded back into a deep hollow on the ulnar side of the middle phalanx; a small radial sesamoid is often present.
The ungual phalanx progressively decreases in size from the first to the fourth.
The most reduced manus in the whole of the mammalia is found in the Horse and its allies, in which the third digit, terminated by a very wide ungual phalanx, is the only one functional.
Megatherium has a greatly modified pes, the hallux is absent, and the second digit vestigial, while the third is very large, having an enormous ungual phalanx.
In the Armadillos the manus is broad, and has strongly developed ungual phalanges.
Just as in the manus, the third and fourth digits are well and subequally developed; their ungual phalanges have the contiguous sides flat, and the axis of the limb passes between them, and between the cuboid and navicular.
It is probable that in these cases the soft parts of the 3d phalanx, and especially the ungual matrix, had not been wholly destroyed.
In some few cases the metatarso-phalangeal joint is affected; but no case has been seen at the base of the ungual phalanx.
The singleungual phalanx is marked by a large subungual process, which is pierced by a considerable foramen.
The branch to digit IV inserts on the base of the ungual phalanx, with one tendinous slip to the distal end of the third phalanx and another to the distal end of the fourth.
The tendon continues along the posterior surface of the hallux and has a double insertion; the main tendon attaches to the base of the ungual phalanx and a smaller branch inserts on the distal end of the proximal phalanx.
The insertion is on the base of the ungual phalanx.
Near the distal end of the proximal phalanx, the tendon passes between two thick bands of fibro-elastic tissue which insert also on the ungual phalanx.
The ungual phalanges are peculiarly long, narrow and curved, instead of being comparatively short and broad, as in most other Moas.
On digit III the lateralmost tendon bifurcates, with one branch attaching to the ungual phalanx and the other to the proximal end of the third phalanx; the medial tendon attaches to the proximal end of the second phalanx.
On digit II the originally medial tendon passes underneath and then lateral to the other tendon and attaches to the ungual phalanx; the other tendon attaches to the proximal end of the second phalanx.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "ungual" in a variety of sentences. We hope that you will now be able to make sentences using this word.
