Question

Determine the correct order for the transmission of a signal through the nervous system.

I. Nerve impulse is triggered
II. Neurotransmitters diffuse across synaptic cleft
III. Receptors bind neurotransmitters
IV. Synaptic vesicles release neurotransmitters
a) I, II, III, IV
b) I, III, IV, II
c) I, IV, II, III
d) II, IV, I, III

Answer 1

The correct order for nerve signal transmission is: nerve impulse is triggered, synaptic vesicles release neurotransmitters, neurotransmitters diffuse across the synaptic cleft, and receptors bind neurotransmitters.

Step-by-step explanation:

The correct order for the transmission of a signal through the nervous system is as follows:

1. Nerve impulse is triggered.
2. Synaptic vesicles release neurotransmitters.
3. Neurotransmitters diffuse across synaptic cleft.
4. Receptors bind neurotransmitters.

This sequence describes the process of synaptic transmission at a chemical synapse. A nerve impulse reaches the synaptic terminal, causing the release of neurotransmitters from synaptic vesicles. These neurotransmitters then diffuse across the synaptic cleft and bind to receptors on the postsynaptic neuron, which can initiate another nerve impulse.
