Fatigue (medical) - Perception of Fatigue

Perception of Fatigue

The sense of fatigue is believed to originate in the reticular activating system of the lower brain. Musculoskeletal structures may have co-evolved with appropriate brain structures so that the complete unit functions together in a constructive and adaptive fashion. The entire systems of muscles, joints, and proprioceptive and kinesthetic functions plus parts of the brain evolve and function together in a unitary way.

Famous quotes containing the words perception of, perception and/or fatigue:

    The most evident difference between man and animals is this: the beast, in as much as it is largely motivated by the senses and with little perception of the past or future, lives only for the present. But man, because he is endowed with reason by which he is able to perceive relationships, sees the causes of things, understands the reciprocal nature of cause and effect, makes analogies, easily surveys the whole course of his life, and makes the necessary preparations for its conduct.
    Marcus Tullius Cicero (106–43 B.C.)

    The near explains the far. The drop is a small ocean. A man is related to all nature. This perception of the worth of the vulgar is fruitful in discoveries. Goethe, in this very thing the most modern of the moderns, has shown us, as none ever did, the genius of the ancients.
    Ralph Waldo Emerson (1803–1882)

    Croft had an instinctive knowledge of land, sensed the stresses and torsions that had first erupted it, the abrasions of wind and water. The platoon had long ceased to question any direction he took; they knew he would be right as infallibly as sun after darkness or fatigue after a long march.
    Norman Mailer (b. 1923)
