Role of Myelin Sheath in Neural Communication

Hard Unit 2: Biological Bases Neural Communication

Neural communication is a complex process that involves various structures and functions within the nervous system. When a neuron receives enough stimulation, it reaches a threshold and generates an action potential. This electrical impulse travels down the axon to reach the axon terminals, where neurotransmitters are released into the synaptic cleft to communicate with the next neuron. Unders\tanding the role of the myelin sheath in this process is crucial.

Which of the following statements best describes the primary role of the myelin sheath in neural communication?

It increases the overall intensity of the neural signal.

It facilitates rapid conduction of action potentials along the axon.

It prevents neurotransmitter release from the presynaptic neuron.

It allows for multiple action potentials to occur simultaneously.

It increases the threshold level needed to trigger an action potential.
