Question

You are attempting question 4 out of 10
1. Isotropic band are elongated during a muscle contraction.
2. Lactic acid accumulation can be caused by repeated activation of the musdes.
3. When a neural signal reaches the motor and plate, acetylcholine is released.
4. A signal sent by CNS through a sensory neuron initiates musde contraction.
Valid statements reated to the mechanism of muscle contraction, form the above are:
4. 1. 2 ad 3 are correct
B. 1 and 3 are correct
C.2 and 3 are correct
D. 1 and 4 are correct​
