Which of the following is an incorrect statement concerning excitation-coupling

Question

Which of the following is an incorrect statement concerning excitation-coupling contraction?
A. Upon binding with ACH, the receptor channel opens allowing Ca2+ to enter the cell. B. The soma gathers input stimuli and then propagates the action potential to the axon. C. Ca2+ serves as a second messenger inside the alpha motor neuron. D. ACH vesicles are stored in the sypnatic terminal of the alpha motor neuron.

Explanation / Answer

Answer-

B is In correct-

B. The soma gathers input stimuli and then propagates the action potential to the axon.

Explaination- All given points are involve in excitation-coupling contraction.

where Soma is non-process portion of a neuron or other brain cell type, containing the cell nucleus. Not involving in input stimuli and propagation of action potential to the axon.
