Nasal Scale
In reptiles, the nasal scale refers to the scale that encloses the nostril.Mallow D, Ludwig D, Nilson G. 2003. True Vipers: Natural History and Toxinology of Old World Vipers. Malabar, Florida: Krieger Publishing Company. 359 pp. . Sometimes this scale is paired (divided). In such cases, the anterior half is referred to as the prenasal and the posterior half is referred to as the postnasal.Wright AH, Wright AA. 1957. Handbook of Snakes. Comstock Publishing Associates (7th printing, 1985). 1105 pp. . Supranasal scales are located above the nasal scale.

It may also be shorthand for the following uses in combination: * With reference to the human nose: ** Nasal administration, a method of pharmaceutical drug delivery * ...

AB126 Nasal Scales
AB1 ''(formally AB Channel 1 until 1995)'' is a French television channel aimed at young adults. History AB1 launched on Eutelsat's Hot Bird satellite and on cable on December 1, 1995 as AB Channel 1 nearly a year before the launch of the AB Sat digital satellite package as that package's premium mini-generalist channel. The first line-up is made up of sitcoms, series and animes from Club Dorothée, of which AB Groupe is a producer. In 1997, the word Channel disappears and the channel takes its current name AB1, including a change of look. In its early days, the channel broadcast American series (new to France) in their original version such as Caroline in the City and Malcolm & Eddie. Among the channel's innovations, it offered a window for African-American sitcoms such as Malcolm & Eddie or the Steve Harvey Show and aired certain seasons of the American talk show, The Jerry Springer Show. In 2000, the channel set up new French programs produced by AB Productions and leavi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nostril
A nostril (or naris , plural ''nares'' ) is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove moisture on exhalation. Fish do not breathe through noses, but they do have two (but cyclostomes have merged into one) small holes used for smelling, which can also be referred to as nostrils. In humans, the nasal cycle is the normal ultradian cycle of each nostril's blood vessels becoming engorged in swelling, then shrinking. The nostrils are separated by the septum. The septum can sometimes be deviated, causing one nostril to appear larger than the other. With extreme damage to the septum and columella, the two nostrils are no longer separated and form a single larger external opening. Like other tetrapods, humans have two external nostrils (anterior nares) and two additi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snake Scales
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, Dibamida ...

Anatomical Terms Of Location
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Nasal (other)
Nasal is an adjective referring to the nose, part of human or animal anatomy. It may also be shorthand for the following uses in combination: * With reference to the human nose: ** Nasal administration, a method of pharmaceutical drug delivery ** Nasal emission, the abnormal passing of oral air through a palatal cleft, or from some other type of pharyngeal inadequacy ** Nasal hair, the hair in the nose * With reference to phonetics: ** Nasalization, the production of a sound with a lowered velum, allowing some of the air to escape through the nose; the resulting being either: *** a nasal consonant, or *** a nasal vowel * With reference to the nose of humans or other animals: ** Nasal bone, two small oblong bones placed side by side at the middle and upper part of the face, and form, by their junction, "the bridge" of the nose ** Nasal cavity, a large air filled space above and behind the nose in the middle of the face ** Nasal concha, a long, narrow and curled bone shelf which prot ...
