24_25 basic physiology of the neuron

What is the function of dendrites?

• Control the metabolism of the neuron cell

• Transmitting the information to the soma

• Transmitting the information to the others cells

• Contain the DNA of neuron

What ion is higher in the extracellular than intracellular and affect the mechanism of action potential in neuron?

• Chloride ion

• Kalium (potassium) ion

• Natrium (sodium) ion

• Organic acid ion

What is the ion channel that affect the depolarization process?

• Voltage-gated sodium channel

• Voltage-gated potassium channel

• Ligand-gated sodium channel

• Ligand-gated potassium channel

What is the main function of myelin in neuron?

• It makes the axon thinner

• It makes the absolute refractory period longer

• It makes the sodium and potassium pump works

• It makes the velocity of conduction faster

What is the name of the synapse that can bring the postsynaptic membrane potential nearer to the threshold potential value?

• Tight junction

• Excitatory post synaptic potential

• Inhibitory post synaptic potential

• Active transport

What is the most affected part of the neuron in the Guillian Barre Syndrome (GBS)?

• Soma

• Dendrites

• Neuromuscular junction

• Myelinated axons
