Cat Anatomy
Cat anatomy comprises the anatomical studies of the visible parts of the body of a domestic cat, which are similar to those of other members of the genus ''Felis''. Mouth Permanent teeth Cats are carnivores that have highly specialized teeth. There are four types of permanent teeth that structure the mouth: twelve ''incisors'', four ''Canine tooth, canines, ''ten ''premolars'' and four ''molar (tooth), molars.'' The premolar and first molar are located on each side of the mouth that together are called the carnassial pair. The carnassial pair specialize in cutting food and are parallel to the jaw. The incisors located in the front section of the lower and upper mouth are small, narrow, and have a single root. They are used for grasping and biting food. Deciduous teeth A cat also has a deciduous dentition prior to the formation of the permanent one. This dentition emerges seven days after birth and it is composed of 26 teeth with slight differences. The mouth will have sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Felis Silvestris Restoration & Skeleton
''Felis'' is a genus of small and medium-sized cat species native to most of Africa and south of 60° latitude in Europe and Asia to Indochina. The genus includes the domestic cat. The smallest of the seven ''Felis'' species is the black-footed cat with a head and body length from . The largest is the jungle cat with a head and body length from . Genetic studies indicate that the Felinae genera ''Felis'', ''Pallas's cat, Otocolobus'' and ''Prionailurus'' diverged from a Eurasian progenitor of the Felidae about 6.2 million years ago, and that ''Felis'' species split off 3.04 to 0.99 million years ago. Etymology The generic name ''Felis'' is derived from Classical Latin meaning 'cat, ferret'. Taxonomy Carl Linnaeus considered ''Felis'' to comprise all cat species known until 1758. Later taxonomists split the Felidae, cat family into different genera. In 1917, the British zoologist Reginald Innes Pocock revised the genus ''Felis'' as comprising only the ones listed in the follow ...

Henry's Pocket
In animal anatomy, Henry's pocket, more formally known as a cutaneous marginal pouch, is a fold of skin forming an open pouch on the lower posterior part of the external ear. The pocket is situated in the approximate location of the antitragus in the human ear. It occurs in a number of mammalian species, including weasels and bats, but is particularly noticeable on the domestic cat, as well as some dog breeds. The pocket is of unknown function, and it is unclear if it has any at all. However, one hypothesis is that it aids in the detection of high-pitched sounds by attenuating lower pitches, especially when the ear is angled, common for a predator when hunting. Since the pocket occurs in a wide variety of mammalian species, it is likely a conserved feature from their common ancestor. The pocket is a common area for parasite Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside anot ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Cat Claw Closeup
The cat (''Felis catus''), also referred to as the domestic cat or house cat, is a small Domestication, domesticated carnivorous mammal. It is the only domesticated species of the family Felidae. Advances in archaeology and genetics have shown that the domestication of the cat occurred in the Near East around 7500 BC. It is commonly kept as a pet and working cat, but also ranges freely as a feral cat avoiding human contact. It is valued by humans for companionship and its ability to kill vermin. Its retractable claws are adapted to killing small prey species such as mice and rats. It has a strong, flexible body, quick reflexes, and sharp teeth, and its night vision and sense of smell are well developed. It is a social species, but a solitary hunter and a crepuscular predator. Cat intelligence is evident in their ability to adapt, learn through observation, and solve problems. Research has shown they possess strong memories, exhibit neuroplasticity, and display cognitive skil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weight-bearing
In orthopedics, weight-bearing is the amount of weight a patient puts on an injured body part. Generally, it refers to a leg, ankle or foot that has been Bone fracture, fractured or upon which surgery has been performed, but the term can also be used to refer to resting on an arm or a wrist. In general, it is described as a percentage of the body weight, because each leg of a healthy person carries the full body weight when walking, in an alternating fashion. After surgery of the hip, or of the bones of the leg, ankle, or foot, it is of the utmost importance for recovery to get the right amount of weight-bearing when moving around with Crutch, crutches or frames. The grades of weight bearing for each phase of recovery will be determined by the surgeon. The Anti-Gravity Treadmill can allow testing of weight bearing by lowering effective body weight in 1% increments from 100 to 20% of body weight.{{Cite journal , last=Henkelmann , first=Ralf , last2=Palke , first2=Lisa , last3=Schnei ...

Locomotion In Animals
In ethology, animal locomotion is any of a variety of methods that animals use to move from one place to another. Some modes of locomotion are (initially) self-propelled, e.g., running, swimming, jumping, flight, flying, hopping, soaring and gliding. There are also many animal species that depend on their environment for transportation, a type of mobility called passive locomotion, e.g., sailing (some jellyfish), ballooning (spider), kiting (spiders), rolling (some beetles and spiders) or riding other animals (phoresis). Animals move for a variety of reasons, such as to foraging, find food, a mating system, mate, a suitable microhabitat, or to escape response, escape predators. For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms. For example, animal migration, migratory animals that travel vast distances (such as the Arctic tern) typically have a locomotion me ...

Gait
Gait is the pattern of Motion (physics), movement of the limb (anatomy), limbs of animals, including Gait (human), humans, during Animal locomotion, locomotion over a solid substrate. Most animals use a variety of gaits, selecting gait based on speed, terrain, the need to wikt:maneuver, maneuver, and energetic efficiency. Different animal species may use different gaits due to differences in anatomy that prevent use of certain gaits, or simply due to evolved innate preferences as a result of habitat differences. While various gaits are given specific names, the complexity of biological systems and interacting with the environment make these distinctions "fuzzy" at best. Gaits are typically classified according to footfall patterns, but recent studies often prefer definitions based on mechanics. The term typically does not refer to limb-based propulsion through fluid mediums such as water or air, but rather to propulsion across a solid substrate by generating reactive forces against ...

Ground Reaction Force
In physics, and in particular in biomechanics, the ground reaction force (GRF) is the force exerted by the ground on a body in contact with it. For example, a person standing motionless on the ground exerts a contact force on it (equal to the person's weight) and at the same time an equal and opposite ground reaction force is exerted by the ground on the person. In the above example, the ground reaction force coincides with the notion of a normal force. However, in a more general case, the GRF will also have a component parallel to the ground, for example when the person is walking – a motion that requires the exchange of horizontal (frictional) forces with the ground. The use of the word reaction Reaction may refer to a process or to a response to an action, event, or exposure.

Digitigrade
In terrestrial vertebrates, digitigrade ( ) locomotion is walking or running on the toes (from the Latin ''digitus'', 'finger', and ''gradior'', 'walk'). A digitigrade animal is one that stands or walks with its toes (phalanges) on the ground, and the rest of its foot lifted. Digitigrades include birds (what many see as bird's knees are actually ankles), cats, dogs, and many other mammals, but not plantigrades (such as humans) or Ungulate, unguligrades (such as horses). Digitigrades generally move more quickly than other animals. There are structural differences between the Limb (anatomy), limb anatomy of plantigrades, unguligrades, and digitigrades. Digitigrade and unguligrade animals have relatively long carpals and tarsus (skeleton), tarsals, and the bones which correspond to the human ankle are thus set much higher in the limb than in a human. In a digitigrade animal, this effectively lengthens the foot, so much so that what are often thought of as a digitigrade animal's "hands ...

Ultraviolet Light
Ultraviolet radiation, also known as simply UV, is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs, Cherenkov radiation, and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. The photons of ultraviolet have greater energy than those of visible light, from about 3.1 to 12 electron volts, around the minimum energy required to ionize atoms. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack sufficient energy, it can induce chemical reactions and cause many substances to glow or fluoresce. Many practical applications, including chemical and biological effects, are derived from the way that UV radiation can interact with organic molecules. These int ...
