Question

Activation of the Golgi tendon organs in the extensors of the right leg would produce what response? A. contraction of the extensors B. contraction of the flexors C. relaxation of the extensors D. relaxation of the flexors Most reflexes are regulated by what type of control? A. Feedforward B. Intupi C. negative feedback D. positive feedback when Ach is released at the motor endplate, which of the following events will occur immediately after? A. Contraction of the muscle B. Opening of Nat ion channels C. Release of Ca++ from sarcoplasmic reticulum D. Movement of troponin and tropomyosin

Explanation / Answer

golgi tendon in the extensor of right leg will produce

B-contraction of the flexors

also followed by relaxation of the extensors of your right leg

most reflex regulated by B-Inhibition

reflexes initiated by giant brainstem cells can be suppressed or facilitated in a number of animals according to moment-to-moment functional requirements.

When ach is released at the motor endplate B opening of Na+ ion channels occur immediately.

After that it release Ca++ from sarcoplasm which lead to movement of troponin and tropomyosin and cause muscle contraction.
