melisa1 [442]

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:

  1. The neurotransmitter molecules are stored in synaptic vesicles.
  2. If the neurotransmitter leak from the vesicles, they are destroyed by enzymes.
  3. During resting condition, they are placed randomly.
  4. 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.

How does ATP provide energy to your body?
olganol [36]
Energy is usually liberated from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate-oxygen groups, leaving adenosine diphosphate (ADT). When the ATP converts to ADP, the ATP is said to be spent.
