During neural signaling in mammals, a neuron resting at approximately –70 mV begins to depolarize due to graded potentials from dendrites. Once the membrane reaches about –55 mV at the axon hillock, a rapid spike to +30 mV occurs. This explosive event is best described as:

​________ is the use of emergent social software platforms within companies.

In diseases such as multiple sclerosis (an example of demyelination in the CNS), the loss of myelin disrupts neural signaling. Based on membrane physiology, what is the most direct consequence of myelin loss?

In vertebrate neurons, the axon hillock serves as the trigger zone for action potential initiation. What structural feature makes this region especially suited for this function?

A sensory neuron in a mammal receives input from multiple upstream neurons before sending a signal toward the spinal cord. Which structural region of the neuron is primarily responsible for increasing surface area to receive these incoming signals and integrate graded potentials?

During an action potential in a vertebrate neuron, the membrane potential rises to approximately +30 mV before beginning to return toward the resting potential of –70 mV. Which ionic movement is primarily responsible for repolarization of the membrane?
