As he spoke, his incisors grew.
They were even with the teeth around them, as if his incisors had just …grown.
Jule had zoomed it in on Xander, the look of predatory cunning – and her blood on his incisors – irritating her as much as it turned her on.
In all cases a more or less full series of teeth is developed, these being differentiated into incisors, canines, premolars and molars, when all are present; but only a single pair of teeth in each jaw has deciduous predecessors.
As regards the teeth, in all cases except the wombats the number of upper incisors differs from that of the corresponding lower teeth.
The first family is that of the true or American opossums- Didelphyidae, in which there are five pairs of upper incisors, while the feet are of the presumed primitive arboreal type, the hind foot having the four outer toes subequal and separate, with the first opposable to them all.
S = 46; with the incisors small and vertical, the outer one in the upper jaw being larger than the others.
Summits of the lower incisors, before they are worn, with a deep transverse groove, dividing it into an anterior and a posterior cusp. Canines long, strong and conical.
The upper incisors are nearly equal and vertical, with the first slightly longer, narrower, and separated from the rest.
Lower incisors sloping forward and upward.
Total 46 - and in having the teeth generally developed upon an insectivorous rather than a carnivorous pattern, the upper middle incisors being larger and inclined forward, the canines relatively smaller, and the molars with broad crowns, armed with prickly tubercles.
There are no external ear-conchs; and the dentition includes four pairs of upper, and three of lower, incisors, and distinctly tritubercular cheek-teeth.
8) has four pairs of upper incisors and long upper canines, while in the lower jaw there is a single pair of procumbent incisors, After Thomas.
As a sub-order, the Paucituberculata are characterized by the presence of four pairs of upper and three of lower incisor teeth; the enlargement and forward inclination of the first pair of lower incisors, and the presence of four or five sharp cusps on the cheek-teeth, coupled with the absence of "syndactylism" in the hind limbs.
The tail is rudimentary, the first hind-toe opposable, the first pair of upper incisors very large, but the second and third either absent or small and placed partially behind the larger pair; and only five pairs of cheek-teeth in each jaw.
The lower incisors are partially inclined forwards, compressed and tapering, bevelled at the ends.
On the other hand, the considerably smaller Nototherium, characterized by its sharp and broad skull and smaller incisors, seems to have been much more wombat-like, and may perhaps have possessed similar burrowing habits.
Pair of large cutting incisors situated close to the middle line, and one great, cutting, compressed premolar, on each side above and below.
The tail is long and in some cases prehensile; the first hind-toe may be either large, small or absent; the dentition usually includes three pairs of upper and one of lower incisors, and six or seven pairs of cheekteeth in each jaw; the stomach is either simple or sadculated, without a cardiac gland; and there are four teats.
With the exception of the aberrant long-snouted phalanger, the members of the family Phalangeridae have the normal number of functional incisors, in addition to which there may be one or two rudimentary pairs in the lower jaw.
The two lower incisors are long, very slender, sharp-pointed and horizontally placed.
3; the incisors being sharp and cutting, o, 3, 3 and those of the lower jaw frequently having a scissor-like action against one another.
In the lower jaw the incisors and canines are directed straight forwards, and are of small size and nearly similar form; the function of the canine being discharged by the first premolar, which is larger than the other teeth of the same series.
The maximum number of teeth is 36, there being typically two pairs of incisors and three of premolars in each jaw.
The incisors are chisel-shaped, and the canines tend to become isolated, so as in the more specialized forms to occupy a more or less midway position in a longer or shorter gap between the incisors and premolars.
The incisors are chisel-shaped; and (unlike the early Hippoidea) there is no gap between the first premolar, when present, and the second.
Of the upper incisors the first and second are nearly equal, with short, broad crowns, the third is large and conical, considerably larger than the canine, which is separated from it by an interval.
Lower incisors diminishing in size from the first to the third; the canine, which is in contact with the third incisor, large and conical, working against (and behind) the canine-like third upper incisor.
Finally, in the Oligocene Colodon the last three upper premolars are like the molars, and the first pair of lower incisors is lost.
In this group the incisors and canines are very variable in number and form; the lower canine being separated by only a short gap from the outer incisor (when present), but by a long one from the first premolar, which is in contact with the second.
With the exception of the first lower premolar, the dentit i on is complete; the incisors being normal, but the canine rudimentary, and the last upper molar distinctly triangular.
The incisors tend to become latera l, the canines are enlarged, and the last upper molar is sub-quadrangular.
Platyrhinus, in which two horns are combined with the presence of upper incisors and lower canines.
It differs from typical rats of the genus Mus by its broader incisors, and the less distinct cusps on the molars.
The tail is short or rudimentary, the incisors are short, and the outer surface of the lower jaw is marked by a distinct ridge.
Other modifications are the loss of the upper incisors; the development of the canines into projecting tusks; and the loss of the anterior premolars.
As regards classification, the first group is that of the Pecora, or Cotylophora, in which the cheek-teeth are selenodont, but there are no upper incisors or canine-like premolars, Pecora.
Inferior incisors, three on each side with an incisiform canine in contact with them.
The cheek-teeth are selenodont, and one pair of upper incisors is retained, while some of the anterior premolars assume a canine-like shape, and are separated from the rest of the cheekseries.
The cheek-teeth are selenodont, as in the two preceding groups; there are no upper incisors, but there are long, narrow and pointed upper canines, which attain a large size in the males; the lower canines are incisor-like, as in the Pecora, and there are no caniniform premolars in either jaw.
There is at least one pair of upper incisors, while the full series of 44 teeth may be present.
Both incisors and canines are devoid of roots and grow throughout life, the canines, and in the typical species one pair of lower incisors, growing to an immense size.
They agree, for instance, with that family in the presence of a descending flange at the hinder end of each side of the lower jaw; but their dentition is of a more generalized type, comprising the full series of 44 teeth, among which the incisors and canines are of normal form, but specially enlarged, and developing roots in the usual manner.
With the single exception of the Indian sloth-bear, all the species have forty-two teeth, of which the incisors and canines closely resemble those of purely carnivorous mammals; while the molars, and especially the one known as the " sectorial " or " carnassial," have their surfaces tuberculated so as to adapt.
By the absence of one pair of upper incisors, the small size of the cheek-teeth and the very extensile character of the lips.
The teeth are usually differentiated into incisors, canines and molars.
-, c.i, p. i, m.; total 44; the upper incisors diminishing rapidly in size from the first to the third, and the lower incisors long, narrow, closely approximated, and almost horizontal in position, their tips inclining towards the middle line, the second slightly larger than the first, the third much smaller.
On the other hand, resemblance to that genus is shown by the reduction of the upper incisors to a single pair.
Even in this the forward direction of the lower incisors is noticeable.
The front surface of the incisors has a broad, shallow groove.
Rodents may be characterized as terrestrial, or in some cases arboreal or aquatic, placental mammals of small or medium size, with a milk and a permanent series of teeth, plantigrade or partially plantigrade, and generally five-toed, clawed (rarely nailed or semi hoofed) feet, clavicles or collar-bones (occasionally imperfect or rudimentary), no canine teeth, and a single pair of lower incisors, opposed by only one similar and functional pair in the upper jaw.
In all rodents the upper incisors resemble the lower ones in growing uninterruptedly from persistent pulps, and (except in the hare group, Duplicidentata) agree with them in number.
- The rodent skull is characterized by the great size of the premaxillae, which completely separate the nasals from the maxillae; by the presence of zygomatic arches; and by the wide unoccupied space existing between the incisors and the cheek-teeth; and (except in the Duplicidentata) by the antero-posteriorly elongated glenoid cavity for the articulation of the lower jaw.
In t he Duplicidentata only is there more than a single pair of incisors, and in these the additional pair is small and placed behind the middle pair.
In this group the enamel extends partially to the back of the incisors, but in all the rest it is restricted to the front surface, so that, by the more rapid wearing-away of the softer structures behind, a chisel-shaped edge is maintained.
Normally, he didn't dampen the pain for the Guardians, who felt the full length of his four inch incisors enter their necks.
It struck her that the red eyes weren't contacts and the four inch incisors weren't implants.
His incisors grew unbidden; he didn't stop them this time.
