Golgi Tendon organs do all of the following except Group of answer choices cause the agonist muscle to contract increase firing
Andre45 [30]

Answer:

None of the listed answers

Explanation:

During muscle contraction, the strands of collagen stretch and the muscle shortens. The Golgi tendon organ sends impulses when the muscle lengthens. This distension deforms the terminals of the sensory fiber of type Ib, whereby the cationic channels sensitive to distension are opened. As a result, the axon becomes depolarized and action potentials are triggered that trigger the nervous impulse towards the central nervous system, through the spinal cord. The frequency of the action potential indicates the force that is converted within the muscle.
