Bristle
A bristle is a stiff hair or feather (natural or artificial), either on an animal, such as a pig, a plant, or on a tool such as a brush or broom. Synthetic types Synthetic materials such as nylon are also used to make bristles in items such as brooms and sweepers. Bristles are often used to make brushes for cleaning purposes, as they are strongly abrasive; common examples include the toothbrush and toilet brush. The bristle brush and the scrub brush are common household cleaning tools, often used to remove dirt or grease from pots and pans. Bristles are also used on brushes other than for cleaning, notably paintbrushes. Bristles are distinguished as ''wikt:flagged, flagged'' (split, bushy ends) or ''unflagged;'' these are also known as ''wikt:flocked, flocked'' or ''unflocked'' bristles. In cleaning applications, flagged bristles are suited for dry cleaning (due to picking up dust better than unflagged), and unflagged suited for wet cleaning (due to flagged ends becoming dirty an ...

Toothbrush
A toothbrush is a special type of brush used to clean the Human tooth, teeth, gingiva, gums, and tongue. It consists of a head of tightly clustered bristles, atop of which toothpaste can be applied, mounted on a handle (grip), handle which facilitates the cleaning of hard-to-reach areas of the mouth. They should be used in conjunction with something to clean between the teeth where the bristles of the toothbrush cannot reach - for example Dental floss, floss, tape, interdental brushes or toothpicks. They are available with different bristle textures, sizes, and forms. Most dentists recommend using a soft toothbrush since hard-bristled toothbrushes can damage tooth enamel and irritate the gums. Because many common and effective ingredients in toothpaste are harmful if swallowed in large doses, tooth paste should instead be spat out. The act of brushing teeth is most often done at a sink within the kitchen or bathroom, where the brush may be rinsed off afterwards to remove any deb ...

Bristle Sensilla
Bristle sensilla are a class of mechanoreceptors found in insects and other arthropods that respond to mechanical stimuli generated by the external world. As a result, they are considered exteroceptors. Bristle sensilla can be divided into two main types, macrochaete and microchaete, based on their size and physiology. The larger macrochaete are thicker and stouter than the smaller microchaete. Macrochaete are also more consistent in their number and distribution across individuals of the same species. Between species, the organization of macrochaete is more conserved among closely related species, whereas the organization of microchaete is more variable and less correlated with phylogenetic relatedness. Each bristle sensillum is composed of a hollow hair with its base fixed to the dendrite of a sensory neuron. The hair acts as a lever. When the hair is deflected, for example by dirt or parasites, force is exerted on the dendrite. This induces mechanotransduction channels to op ...

Bristlebird
The bristlebirds are a family of passerine birds, Dasyornithidae. There are three species in one genus, ''Dasyornis''. The family is endemic to the south-east coast and south-west corner of Australia.Del Hoyo, J.; Elliot, A. & Christie D. (editors). (2006). ''Handbook of the Birds of the World. Volume 12: Picathartes to Tits and Chickadees''. Lynx Edicions. The genus ''Dasyornis'' was sometimes placed in the Acanthizidae or, as a subfamily, Dasyornithinae, along with the Acanthizinae and Pardalotinae, within an expanded Pardalotidae, before being elevated to full family level by Christidis & Boles (2008).Higgins, P.J.; & Peter, J.M.

Paintbrush Closeup
A paintbrush is a brush used to apply paint or ink. A paintbrush is usually made by clamping bristles to a handle with a ferrule. They are available in various sizes, shapes, and materials. Thicker ones are used for filling in, and thinner ones are used for details. They may be subdivided into decorators' brushes used for painting and decorating and artists' brushes use for visual art. History Paintbrushes were used by humans as early as the Paleolithic era in around 2.5 million years ago in order to apply pigment. Old painting kits, estimated to be around 100,000 years old, were discovered in a cave in what is now modern South Africa. Ancient Egyptian paintbrushes were made of split palm leaves and used by ancestors to beautify their surroundings. The oldest brushes ever found were also made of animal hair. Parts * Bristles: Transfer paint onto the substrate surface * Ferrule: Retains the bristles and attaches them to the handle * Handle: The intended interface between ...

Broom
A broom (also known as a broomstick) is a cleaning tool, consisting of usually stiff fibers (often made of materials such as plastic, hair, or corn husks) attached to, and roughly parallel to, a cylindrical handle, the broomstick. It is thus a variety of brush with a long handle. It is commonly used in combination with a dustpan. A distinction is made between a "hard broom" and a "soft broom" and a spectrum in between. Soft brooms are used in some cultures chiefly for sweeping walls of cobwebs and spiders, like a " feather duster", while hard brooms are for rougher tasks like sweeping dirt off sidewalks or concrete floors, or even smoothing and texturing wet concrete. The majority of brooms are somewhere in between, suitable for sweeping the floors of homes and businesses, soft enough to be flexible and to move even light dust, but stiff enough to achieve a firm sweeping action. The broom is also a symbolic object associated with witchcraft and ceremonial magic. Etymology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristle-thighed Curlew
The bristle-thighed curlew (''Numenius tahitiensis'') is a medium-sized shorebird that breeds in Alaska and winters on tropical Pacific islands. It is known in Mangareva as ''kivi'' or ''kivikivi'' and in Rakahanga as ''kihi''; it is said to be the origin of the name for the New Zealand flightless bird kiwi although some linguists like Robert Blust has proposed an alternate origin from Proto-Oceanic *''kiwiwi'', the Pacific golden plover, instead. Taxonomy The bristle-thighed curlew was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it in the genus '' Scolopax'' and coined the binomial name ''Scolopax tahitiensis''. Gmelin based his description on the "Otaheite curlew" that had been described in 1785 by the English ornithologist John Latham in his ''A General Synopsis of Birds''. "Otaheite" is a former name of Tahiti. The specimen used by Latham was supplied by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feather
Feathers are epidermal growths that form a distinctive outer covering, or plumage, on both avian (bird) and some non-avian dinosaurs and other archosaurs. They are the most complex integumentary structures found in vertebrates and an example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant birds from other living groups. Although feathers cover most of the bird's body, they arise only from certain well-defined tracts on the skin. They aid in flight, thermal insulation, and waterproofing. In addition, coloration helps in communication and protection. The study of feathers is called plumology (or plumage science). People use feathers in many ways that are practical, cultural, and religious. Feathers are both soft and excellent at trapping heat; thus, they are sometimes used in high-class bedding, especially pillows, blankets, and mattresses. They are also used as filling for winter clothing and outdoor bedding, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brush
A brush is a common tool with bristles, wire or other filaments. It generally consists of a handle or block to which filaments are affixed in either a parallel or perpendicular orientation, depending on the way the brush is to be gripped during use. The material of both the block and bristles or filaments is chosen to withstand hazards of its intended use, such as corrosive chemicals, heat or abrasion. It is used for cleaning, grooming hair, make up, painting, surface finishing and for many other purposes. It is one of the most basic and versatile tools in use today, and the average household may contain several dozen varieties. History When houses were first inhabited, homeowners used branches taken from shrubs to sweep up dirt, hence using the first brushes. In 1859, the first brush factory in America was set up in New York. Manufacture A common way of setting the bristles, brush filaments, in the brush is the staple or anchor set brush in which the filament is forced w ...

Toilet Brush
A toilet brush is a tool for cleaning a toilet bowl. Generally the toilet brush is used with toilet cleaner or bleach. The toilet brush can be used to clean the upper area of the toilet, around the bowl. However, it cannot be used to clean very far into the toilet's Trap (plumbing), U-bend and should absolutely not be used to clean the toilet seat. In many cultures it is considered impolite to clean away biological debris without the use of chemical toilet cleaning products, as this can leave residue on the bristles. By contrast, others consider it impolite not to clean away biological debris immediately using the toilet brush. A typical toilet brush consists of a hard bristled end, usually with a rounded shape and a long handle. Today toilet brushes are commonly made of plastic, but were originally made of wood with pig bristles or from the hair of horses, oxen, squirrels and badgers. The brush is typically stored in a holder, but in some cases completely hidden in a tube. An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trinity Bristle Snail
The Trinity bristle snail (''Monadenia setosa'') is a species of medium-sized land snail, a terrestrial pulmonate gastropod mollusc in the family Monadeniidae. Description The Trinity bristle snail attains a body length of approximately 2.5 cm. It is brown or chestnut-colored and covered with minuscule, translucent bristles, which give the species its common name. Distribution and habitat This species is endemic to California. This snail is found in northwestern Trinity County, along the Trinity River, up some of its tributaries and into the Corral Bottom area. It has a healthy population within its territory. It likes cool, wet, shady riparian zones, and prefers areas with a deciduous understory. Ecology The Trinity bristle snail is dependent on cool, moist conditions, and therefore it is only active at night. It spends warmer parts of the day stuck to shady areas on tree trunks, and in especially warm parts of the summer it may not move for days. When conditions are coo ...
