Laterality
The term laterality refers to the preference most humans show for one side of their body over the other. Examples include left-handedness/right-handedness and left/right-footedness; it may also refer to the primary use of the left or right hemisphere in the brain. It may also apply to animals or plants. The majority of tests have been conducted on humans, specifically to determine the effects on language. Human The majority of humans are right-handed. Many are also right-sided in general (that is, they prefer to use their right eye, right foot and right ear if forced to make a choice between the two). The reasons for this are not fully understood, but it is thought that because the left cerebral hemisphere of the brain controls the right side of the body, the right side is generally stronger; it is suggested that the left cerebral hemisphere is dominant over the right in most humans because in 90-92% of all humans, the left hemisphere is the language hemisphere.

Ambidexterity
Ambidexterity is the ability to use both the right and left hand equally well. When referring to objects, the term indicates that the object is equally suitable for right-handed and left-handed people. When referring to humans, it indicates that a person has no marked preference for the use of the right or left hand. Only about one percent of people are naturally ambidextrous, which equates to about 70,000,000 people in the world. In modern times, it is common to find some people considered ambidextrous who were originally left-handed and who learned to be ambidextrous, either deliberately or as a result of training in schools or in jobs where right-handed habits are often emphasized or required. Since many everyday devices (such as can openers and scissors) are asymmetrical and designed for right-handed people, many left-handers learn to use them right-handedly due to the rarity or lack of left-handed models. Thus, left-handed people are more likely to develop motor skills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Right-handed
In human biology, handedness is an individual's preferential use of one hand, known as the dominant hand, due to it being stronger, faster or more dextrous. The other hand, comparatively often the weaker, less dextrous or simply less subjectively preferred, is called the non-dominant hand. In a study from 1975 on 7688 children in US grades 1-6, Left handers comprised 9.6% of the sample, with 10.5% of male children and 8.7% of female children being left-handed. Handedness is often defined by one's writing hand, as it is fairly common for people to prefer to do some tasks with each hand. There are examples of true ambidexterity (equal preference of either hand), but it is rare—most people prefer using one hand for most purposes. Most of the current research suggests that left-handedness has an epigenetic marker—a combination of genetics, biology and the environment. Because the vast majority of the population is right-handed, many devices are designed for use by right-hand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lateralization Of Brain Function
The lateralization of brain function is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum. Although the macrostructure of the two hemispheres appears to be almost identical, different composition of neuronal networks allows for specialized function that is different in each hemisphere. Lateralization of brain structures is based on general trends expressed in healthy patients; however, there are numerous counterexamples to each generalization. Each human's brain develops differently, leading to unique lateralization in individuals. This is different from specialization, as lateralization refers only to the function of one structure divided between two hemispheres. Specialization is much easier to observe as a trend, since it has a stronger anthropological history. The best examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Footedness
Footedness is the natural preference of one's left or right foot for various purposes. It is the foot equivalent of handedness. While purposes vary, such as applying the greatest force in a certain foot to complete the action of kick as opposed to stomping, footedness is most commonly associated with the preference of a particular foot in the leading position while engaging in foot- or kicking-related sports, such as association football and kickboxing. A person may thus be left-footed, right-footed or ambipedal (able to use both feet equally well). Ball games In association football, the ball is predominantly struck by the foot. Footedness may refer to the foot a player uses to kick with the greatest force and skill. Most people are right-footed, kicking with the right leg. Capable left-footed footballers are rare and therefore quite sought after. As rare are "two-footed" players, who are equally capable with both feet. Such players make up only one sixth of players in the top prof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cross-dominance
Cross-dominance, also known as mixed-handedness, hand confusion, or mixed dominance, is a motor skill manifestation in which a person favors one hand for some tasks and the other hand for others, or a hand and the contralateral leg. For example, a cross-dominant person might write with the right hand and do everything else with the left one, or manage and kick a ball preferentially with the left leg. It can also refer to mixed laterality, which refers to a person favoring eyes, ears, feet, or hands on one side of the body. A person who is cross-dominant can also be stronger on the opposite side of the body that they favor; for example, a right-handed person can be stronger on the left side. Cross-dominance can often be a problem when shooting or in activities that require aim, although athletes can still achieve success in sports that require accuracy, like passing in American football and shooting in basketball.

Cricket
Cricket is a bat-and-ball game played between two teams of eleven players on a field at the centre of which is a pitch with a wicket at each end, each comprising two bails balanced on three stumps. The batting side scores runs by striking the ball bowled at one of the wickets with the bat and then running between the wickets, while the bowling and fielding side tries to prevent this (by preventing the ball from leaving the field, and getting the ball to either wicket) and dismiss each batter (so they are "out"). Means of dismissal include being bowled, when the ball hits the stumps and dislodges the bails, and by the fielding side either catching the ball after it is hit by the bat, but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease in front of the wicket. When ten batters have been dismissed, the innings ends and the teams swap roles. The game is adjudicated by two umpires, aided by a third umpire and match referee ...

North Staffordshire Royal Infirmary
The North Staffordshire Royal Infirmary was a hospital at Hartshill in the English county of Staffordshire. It was located half a mile east of the site of the Royal Stoke University Hospital. It was run by the University Hospitals of North Midlands NHS Trust. History The original hospital in the area was established at Etruria in 1804 but was completely rebuilt on a much larger basis in 1814. The hospital then relocated to Hartshill as the North Staffordshire Royal Infirmary in 1869. It became the North Staffordshire Infirmary and Eye Hospital in 1890 and the North Staffordshire Royal Infirmary in 1925. The facility joined the National Health Service in 1948 and, after services were transferred to the Royal Stoke University Hospital Royal Stoke University Hospital (formerly the University Hospital of North Staffordshire) is a teaching and research hospital at Hartshill in the English county of Staffordshire.

Bowling (cricket)
Bowling, in cricket, is the action of propelling the ball toward the wicket defended by a batter. A player skilled at bowling is called a ''bowler''; a bowler who is also a competent batter is known as an all-rounder. Bowling the ball is distinguished from ''throwing'' the ball by a strictly specified biomechanical definition, which restricts the angle of extension of the elbow. A single act of bowling the ball towards the batsman is called a ''ball'' or a '' delivery''. Bowlers bowl deliveries in sets of six, called an ''over''. Once a bowler has bowled an over, a teammate will bowl an over from the other end of the pitch. The Laws of Cricket govern how a ball must be bowled. If a ball is bowled illegally, an umpire will rule it a ''no-ball''. If a ball is bowled too wide of the striker for the batsman to be able to play at it with a proper cricket shot, the bowler's end umpire will rule it a ''wide''. There are different types of bowlers, from fast bowlers, whose primary w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
