Bottle Sling
The bottle sling (also called a jug sling, a Hackamore knot, or a Scoutcraft knot) is a knot which can be used to create a handle for a glass or ceramic container with a slippery narrow neck, as long as the neck widens slightly near the top. While classed with binding knots, such as the reef knot and miller's knot, the bottle sling is able to perform a function for which most other binding knots are unsuited. The bottle sling's specific form allows it to grip a cylinder, assuming it has even a slight flare or collar, and lift it along its axis when the knot is loaded by all four strands. With appropriate size cord, most wine bottles can be reliably suspended with this knot. History The bottle sling was described in detail by the Greek physician Heraklas in his first century monograph on surgical knots and slings. It was included under the name ''diplous karkhesios brokhos'' ("double jug-sling noose"). Clearly familiar with the knot, Heraklas provided three distinct tying m ...

Jury Mast Knot
The jury mast knot (or masthead knot) is traditionally used for jury rigging a temporary mast on a sailboat or ship after the original one has been lost. The knot is placed at the top of a new mast with the mast projecting through the center of the knot. The loops of the knot are then used as anchor points for makeshift stays and shrouds. Usually small blocks of wood are affixed to, or a groove cut in, the new mast to prevent the knot from sliding downwards.Clifford W. Ashley, ''The Ashley Book of Knots'' (New York: Doubleday, 1944), 212. Due to a lack of hard historical evidence there is uncertainty whether this supposed rigging knot was ever commonly used for rigging jury masts.Charles Hamel, "Investigations on the Jury Mast Knot [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joint Dislocation
A joint dislocation, also called luxation, occurs when there is an abnormal separation in the joint, where two or more bones meet.Dislocations. Lucile Packard Children’s Hospital at Stanford. Retrieved 3 March 2013 A partial dislocation is referred to as a subluxation. Dislocations are often caused by sudden trauma on the joint like an impact or fall. A joint dislocation can cause damage to the surrounding ligaments, tendons, muscles, and nerves. Dislocations can occur in any major joint (shoulder, knees, etc.) or minor joint (toes, fingers, etc.). The most common joint dislocation is a shoulder dislocation. Treatment for joint dislocation is usually by closed reduction, that is, skilled manipulation to return the bones to their normal position. Reduction should only be performed by trained medical professionals, because it can cause injury to soft tissue and/or the nerves and vascular structures around the dislocation. Symptoms and signs The following symptoms are common with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trumpet Knot
The trumpet is a brass instrument commonly used in classical and jazz ensembles. The trumpet group ranges from the piccolo trumpet—with the highest register in the brass family—to the bass trumpet, pitched one octave below the standard B or C trumpet. Trumpet-like instruments have historically been used as signaling devices in battle or hunting, with examples dating back to at least 1500 BC. They began to be used as musical instruments only in the late 14th or early 15th century. Trumpets are used in art music styles, for instance in orchestras, concert bands, and jazz ensembles, as well as in popular music. They are played by blowing air through nearly-closed lips (called the player's embouchure), producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century, trumpets have primarily been constructed of brass tubing, usually bent twice into a rounded rectangular shape. There are many distinct ty ...

Physiology
Physiology (; ) is the scientific study of functions and mechanisms in a living system. As a sub-discipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out the chemical and physical functions in a living system. According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology. Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells. ''Physiological state'' is the condition of normal function. In contrast, ''pathological state'' refers to abnormal conditions, including human diseases. The Nobel Prize in Physiology or Medicine is awarded by the Royal Swedish Academy of Sciences for exceptional scientific achievements in physiology related to the field of medicine.

Hackamore
A hackamore is a type of animal headgear which does not have a bit. Instead, it has a special type of noseband that works on pressure points on the face, nose, and chin. Hackamores are most often seen in western riding and other styles of riding derived from Spanish traditions, and are occasionally seen in some English riding disciplines such as show jumping and the stadium phase of eventing. Various hackamore designs are also popular for endurance riding. While usually used to start young horses, they are often seen on mature horses with dental issues that make bit use painful, and on horses with mouth or tongue injuries that would be aggravated by a bit. Some riders also like to use them in the winter to avoid putting a frozen metal bit into a horse's mouth. There are many styles, but the classic hackamore is a design featuring a ''bosal'' noseband, and sometimes itself called a "bosal" or a "bosal hackamore". It has a long rope rein called a mecate and may also add a ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bosal
A bosal (, , or ) is a type of noseband used on the classic hackamore of the ''vaquero'' tradition. It is usually made of braided rawhide and is fitted to the horse in a manner that allows it to rest quietly until the rider uses the reins to give a signal. It acts upon the horse's nose and jaw. Though seen in both the "Texas" and the "California" cowboy traditions, it is most closely associated with the "California" style of western riding.Price, Steven D. (ed.) ''The Whole Horse Catalog: Revised and Updated'' New York:Fireside 1998 p. 158-159 Sometimes the term ''bosal'' is used to describe the entire classic hackamore or ''jaquima.'' Technically, however, the term refers only to the noseband portion of the equipment. Bosals come in varying diameters and weights, allowing a more skilled horse to "graduate" into ever lighter equipment. Once a young horse is solidly trained with a bosal, a bit is added and the horse is gradually shifted from the hackamore to a bit. Descript ...

Fiador (tack)
A fiador () term of Spanish colonial origin referring to a hackamore component used principally in the Americas. In English-speaking North America, the fiador is known principally as a type of throatlatch used on the bosal-style hackamore. Its purpose is to stabilize a heavy noseband or bosal and prevent the bridle from shifting. It is not used for tying the horse. A fiador-like design and fiador knot is also used under the jaw on some rope halters, usually ending in a loop to which a lead rope can be attached. This, however, is not an independent "fiador", nor generally labeled as such; it is simply an integral part of the halter itself. Origins The origin of the word ''fiador'' in its equestrian sense is obscure but appears to be of South American origin. In Spanish, the word ''fiador'' has numerous senses, all related to safekeeping. For example, an 18th-century Spanish—English dictionary defines ''fiador'' as ''surety, bail; he that is bound for another. In falconry, ...

Equestrianism
Equestrianism (from Latin , , , 'horseman', 'horse'), commonly known as horse riding (Commonwealth English) or horseback riding (American English), includes the disciplines of riding, Driving (horse), driving, and Equestrian vaulting, vaulting. This broad description includes the use of horses for practical working animal, working purposes, transportation, recreational activities, artistic or cultural exercises, and animals in sport, competitive sport. Overview of equestrian activities Horses are horse training, trained and ridden for practical working purposes, such as in Mounted police, police work or for controlling herd animals on a ranch. They are also used in Horse#Sport, competitive sports including dressage, endurance riding, eventing, reining, show jumping, tent pegging, equestrian vaulting, vaulting, polo, horse racing, driving (horse), driving, and rodeo (see additional equestrian sports listed later in this article for more examples).

Rein
Reins are items of horse tack, used to direct a horse or other animal used for riding. They are long straps that can be made of leather, nylon, metal, or other materials, and attach to a bridle via either its bit or its noseband. Use for riding Reins are used to give subtle commands or cues, also known as rein aids. Various commands may signal a turn, ask for a slower speed, request a halt or rein back. Rein aids are used along with leg aids, shifting of body weight, and sometimes voice commands. Harness reins On some types of harnesses there might be supporting rings or "terrets" used to carry the reins over the animal's back. When pairs of equines are used in drawing a wagon or coach it is usual for the outer side of each pair to be connected to the reins and for the inside of the bits to be connected between the pair of horses by a short bridging strap or rope. The driver carries "four-in-hand" or "six-in-hand" being the number of reins connecting to the pairs. O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noseband
A noseband is the part of a horse's bridle that encircles the nose and jaw of the horse. In English riding, where the noseband is separately attached to its own headstall or crownpiece, held independently of the bit, it is often called a cavesson or caveson noseband. In other styles of riding, a simple noseband is sometimes attached directly to the same headstall as the bit. Development A noseband may have been one of the first tools used by humans to domesticate and ride horses. The bit developed later. The noseband was originally made of leather or rope. After the invention of the bit, the noseband was, in some cultures, demoted to a halter worn beneath the bridle that allowed the rider to remove the bit from the horse's mouth after work and leave a restraining halter on underneath, or to tie the horse by this halter, instead of by the bit, which could result in damage to the horse's mouth if it panicked. However, its ability to hold a horse's mouth shut over the bit was also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mandible
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower tooth, teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed prenatal development, in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from ''wikt:mandere ...
