Nerve impluse transmission at neuromuscular junction requires
Nerve impluse transmission at neuromuscular junction requires
Open in App
Solution
The correct option is B Ca
Synaptic transmission at the neuromuscular junction begins when an action potential reaches the presynaptic terminal of a motor neuron, which activates voltage-gated calcium channels to allow calcium ions to enter the neuron. Calcium ions bind to sensor proteins on synaptic vesicles, triggering vesicle fusion with the cell membrane and subsequent neurotransmitter release from the motor neuron into the synaptic cleft.Hence, the correct answer is (A)
