Which of the following is found in the PNS and NOT in the CNS?
Efficient transmission of the electrochemical signal requires multiple breaks along the myelinated axon.
What are these "breaks" called?
nodes of ranvier
What type of neuron is responsible for sending signals to muscles?
Which statement about the functions of glial cells is FALSE?
Schwann cells cushion the brain against injury CorrectCorrect. This statement is FALSE. Schwann cells myelinate axons in the PNS; they don't protect against brain injury.
The action potential is a spike of electrical activity that starts when ___________ ions rush into the neuron and cause its voltage to ____________.
Sodium (NA+); rise
Which types of cells play important supporting roles within the nervous system?
____________________ are the first regions of the neuron to receive electrochemical signals.
Which is NOT an important function of the nervous system?
To transport nutrients throughout our bodies. CorrectCorrect. The nervous system sends signals, but not nutrients.
A type of neuron that is important for hearing is located in the PNS. In this type of neuron, signals are received by one dendrite, travel to the cell body, and then through the axon towards the brain.
What type of neuron is this?
Which of the following terms refers to gray matter?
When an excitatory neurotransmitter binds to the dendrites of a neuron, it makes the neuron more likely to fire a(n) ______________________ in the axon.
The brainstem is __________________ to the cerebrum.
Action potentials are characterized by which of the following?
A spike in membrane potential in the axon.
Which gyrus is located on the surface of the posterior frontal lobe and is responsible for control of voluntary movements?
Identify the lobe in which the following structures are found: Heschl's gyrus and Wernicke's area.
This part of the brain is responsible for the perception of stimuli like touch, pressure, temperature and pain.
What speech and language region is found in the left inferior frontal gyrus?
The corpus callosum ___________
Transmits neural signals between the two cerebral hemispheres.
What are all of these: inferior frontal gyrus, Heschl's gyrus, supramarginal gyrus?
What role does the anterior temporal lobe play in speech, language, or hearing?
