The subcellular structures of neuron that forms the basis for transmission of nerve impulses are the synaptic vesicles.
What are the steps in impulse transmission between neurons?
- The action potential or nerve impulse reaches the <u>axon</u> of neuron and depolarises the membrane.
- Voltage gated Calcium channels open .
- Arrival of action potential causes the synaptic vesicle to attach to presynaptic membrane.
- Calcium influx triggers release of neurotransmitter.
- This neurotransmitters bind to postsynaptic membrane and new impulses are created.
Synaptic vesicle under resting condition:
- The neurotransmitter molecules are stored in synaptic vesicles.
- If the neurotransmitter leak from the vesicles, they are destroyed by enzymes.
- During resting condition, they are placed randomly.
- When an impulse reaches the axon, vesicles are arranged in the presynaptic membrane.
Thus from the above we can conclude that, synaptic vesicles are the subcellular structures in transmission of nerve impulses and , under resting condition they are placed randomly.

Habitat loss..The most harmful threat to biodiversity is the D. Habitat loss.
It's not easy to live in a place that you no longer have any means of living. If ones organism loss his habitat, chances are they will extinct because of the absence of their basic needs.
Answer: 77.0J
Explanation:
The magnetic field is given as 4.40T
Since the volume is not given, we assume that the volume is 10.0cm³
We need to find the magnetic field energy in this volume.
The energy density is:
u = B²/2u•
u• is given as 4π × 10^-7 T.m/A
Using this formula we substitute
u = B²/2u• = (4.40 T)²/ 2(4π × 10^-7 T.m/A) = 7.704 × 10^6 J/m³
The energy is equal to the energy density multiply by the volume. You get;
U= uV = (7.704 × 10^6 J/m³) × (10.0 × 10^6m³) = 77.0J
