Coordination of Fine Motricity - Monograph and TCC Subject
To Coordinate literally means to order. Under the motricity concept it could be said that: "the motor coordination is the sort of driving units involved in a movement" to "order the phases of movement in its structure and biomechanics in the pace of movement."
The Monograph AC took this article as a way to explain a theme for both a monograph of Medicine as of Psychoeducational or Physical Education.
Motor coordination is the planning, organization of actions driven towards a determined goal. The fine motricity is organised by the same units.
The study of neurological motor units was conducted by Fernstein and collaborators, and Christensen found that large differences in the average number of fibre per mobility unit: from the opponent to the thumb with thirteen neuron cells by the skin of the neck with twenty-two and smaller units , Or the twin which have over thousand neuronal fibres.
These figures confirm that the muscles with delicate movements, such as motor skills, have smaller units than the postural muscles of activities and charged by strong impulses that have units with large number of muscle cells, (Linch 1970).
All movements are composed by combinations of contractions of motor units ordered in its action to produce the momentum created.
Every muscle is composed by a number of muscle cells which, in turn, are innervated by several motor neurons. In each muscle there are several hundred mobility units in perfect organization to its contraction.
According to the function of each muscle, the mobility units are formed by a greater or lesser number of muscle cells by motoneuron. (Fox, E. 1984).
Thus, the muscles of motor skills have smaller units than the postural muscles that present a greater number of units. (Morehouse 1974).
Many bibliographies were launched on the subject, allowing a detailed analysis to a monograph or a TCC
With this organization, where each mobility unit intervenes at the right time, as often necessary and in line with the order of the brain that comes to it, this system produces a rich and varied form of a symphony movement, related to any other artistic form.
This mobility is regulated by units responsible for these movements. The radial, ulnar and median nerves are responsible for bringing the orders of contraction and regulate the movements of the hand and fingers.
The muscles of the forearm, hand and fingers form a masterful combination with an order and perfection of biomechanical functions, allowing the richness of movements that hold our hands. (Kendall 1974).
Describing all muscles would be excessive for this work, so we describe as a whole according to the office. Thus, teachers of Monograph AD chose to focus efforts
The flexor are those who are responsible for flexing the hand and fingers.
Since the Palms to greater and lesser flexor fingers have specific functions.
In the analysis kinematics are responsible for establishing the vertical tracks. The first is that dominates. The expanders are antagonists of the flexor and so their function and movements are directed towards to the extension of the hand and fingers.
The abductors (those that fall outside the zone of fat finger) the abductor long and short of thumb, are those who are responsible for separating the thumb fingers of the other fingers.
This neuromuscular regulation has a dual function. While mobility units are activated, there are other operating units of perception.
