Which one of the following divisions of the nervous system predominates during the relaxed state?

The absolute refractory period characteristic of neurons is important in ensuring that action potentials travel in only one direction.

Recordings of the brain's activities can be made using a(n) ________; this information is used to study the functioning of the brain.

The first step of an action potential, when the membrane potential of a neuron shifts from negative to positive due to inward movement of sodium ions, is referred to as ________.

Cells that provide direct protection and physical support to neurons are

Depicted in the figure above, ________ is a type of neural information processing where an action potential is transmitted from one cell to many cells.

From an evolutionary standpoint, which of the following structures is considered the oldest, most primitive division of the brain?
