Contrast To Stretch Reflex
The stretch reflex operates as a feedback mechanism to control muscle length by causing muscle contraction. In contrast, the tendon reflex operates as a feedback mechanism to control muscle tension by causing muscle relaxation before muscle force becomes so great that tendons might be torn. Although the tendon reflex is less sensitive than the stretch reflex, it can override the stretch reflex when tension is great, making you drop a very heavy weight, for example. Like the stretch reflex, the tendon reflex is ipsilateral. The sensory receptors for this reflex are called tendon Golgi receptors, which lie within a tendon near its junction with a muscle. In contrast to muscle spindles, which are sensitive to changes in muscle length, tendon organs detect and respond to changes in muscle tension that are caused by muscular contraction, but not passive stretch.

Famous quotes containing the words contrast to, contrast, stretch and/or reflex:
“At this age [9–12], in contrast to adolescence, girls still want to know their parents and hear what they think. You are the influential ones if you want to be. Girls, now, want to hear your point of view and find out how you got to be what you are and what you are doing. They like their fathers and mothers to be interested in what they’re doing and planning. They like to know what you think of their thoughts.”
—Stella Chess (20th century)
“Flowers and fruits are always fit presents; flowers, because they are a proud assertion that a ray of beauty outvalues all of the utilities of the world. These gay natures contrast with the somewhat stern countenance of ordinary nature: they are like music heard out of a work-house.”
—Ralph Waldo Emerson (1803–1882)
“Idleness and constancy fix the mind to what it finds easy and agreeable. This habit always confines and cramps up our knowledge; and no one has ever taken the trouble to stretch and carry his understanding as far as it could go.”
—François, Duc De La Rochefoucauld (1613–1680)
“No sooner does a great man depart, and leave his character as public property, than a crowd of little men rushes towards it. There they are gathered together, blinking up to it with such vision as they have, scanning it from afar, hovering round it this way and that, each cunningly endeavouring, by all arts, to catch some reflex of it in the little mirror of himself.”
—Thomas Carlyle (1795–1881)
