B)motor nerve $\rightarrow$  synaptic cleft $\rightarrow$ sarcolemma $\rightarrow$ sarcoplasmic reticulum $\rightarrow$ troponin
C)motor nerve $\rightarrow$  sarcoplasmic reticulum $\rightarrow$ synaptic cleft $\rightarrow$  sarcolemma $\rightarrow$  troponin
D)motor nerve $\rightarrow$  sarcolemma $\rightarrow$ sarcoplasmic reticulum $\rightarrow$  synaptic cleft $\rightarrow$  troponin
E)motor nerve $\rightarrow$  sarcolemma $\rightarrow$  synaptic cleft $\rightarrow$ sarcoplasmic reticulum $\rightarrow$  troponin

Quizplus · Accepted Answer

The correct order of structures that a motor nerve stimulation encounters when triggering a contraction is motor nerve ➞ synaptic cleft ➞ sarcolemma ➞ sarcoplasmic reticulum ➞ troponin. Choice B follows this sequence correctly.
