Nervous Flashcards
To understand a word that one hears, action potentials from the ear reach the auditory cortex, travel to the auditory association cortex, and are comprehended as meaningful words by:
Wernicke (sensory speech) area
An action potential occurs:
if the membrane potential
reaches a threshold value.

cortex.

Voltage-gated ion channels:
Both ‘'’open in response to changes in the membrane potential’’’ and ‘‘are responsible for the generation of the action potential in neurons’’’ are correct.
The numerous raised folds on the * surface of each cerebral hemisphere are called
gyri

Which of the following would be an expected symptom of damage to the temporal lobe?

Gaps between segments of oligodendrocytes or between individual Schwann cells are called
nodes of Ranvier
A group of nuclei scattered throughout the brainstem that play a role in arousing and maintaining consciousness are collectively called the
reticular formation
In a neuron, short, branching cytoplasmic extensions that receive information and carry it to the cell body are called
dendrites
