Ray Of Light [21]

Small, electron-lucent vesicles known as synaptic vesicles (SVs) are grouped at presynaptic terminals. They hold neurotransmitters and exocytosis, which is stimulated by calcium, releases them. After exocytosis, SVs are formed locally at the terminals.

  • From the presynaptic cell with synaptic vesicles to the postsynaptic cell with neurotransmitter receptors, a signal always moves in one direction across the chemical synapse.
  • The correct routing of nerve signals throughout the body is guaranteed by this one-way communication.
  • A signal is transmitted from one neuron—the presynaptic, or sending, neuron—to another neuron—the postsynaptic, or receiving, neuron—at the synapse, increasing or decreasing the likelihood that the postsynaptic neuron will fire its own action potential.
  • The stimulation causes a sensory neuron to go into an action potential, which alters the motor neuron's potential.
  • Excitatory because it tends to depolarize the cell, this potential is known as an excitatory postsynaptic potential (EPSP).

The answer is D) It will allow scientists to make personalized medicine.
