Exam 4: The Brain and Nervous System

A neuron is also called a:

The myelin sheath in the central nervous system is made up of:

_______________ is a protein that picks up a neurotransmitter from the synaptic cleft after it has been released and transports it back to the sending neuron for recycling.

A brain without a peripheral nervous system would be like a radio without a receiver. Explain what is meant by this analogy.

The brain's ability to change and adapt in response to experience through neurogenesis or by reorganizing or growing new neural connections is called:

A nerve is a bundle of:

If you look straight ahead, then everything in the left side of the scene before you goes to the:

_______________ allow(s) scientists to see the neural activity associated with each of the series of steps associated with a thought in real time.

Although it is relatively small in rodents, the _______________ accounts for approximately one-third of the entire cortex in human beings.

Which is the only sense that completely bypasses the thalamus? How is memory related to this particular sense?

Which of the following regions in the brain is involved in language comprehension?

Which technique uses radio frequencies and a magnetic field to produce images of the brain?

Patients with _______________ hemisphere damage in the brain may have difficulty identifying faces, interpreting emotional expressions in a face or voice, or understanding music or art.

When an action potential reaches the end of the axon terminal:

Neuroscientists have found that _______________ can inhibit the process of neurogenesis.

When a neurotransmitter molecule binds briefly with a receptor site, changes occur in the receiving neuron's charge. If there is a voltage shift in a positive direction, then the effect is:

Many axons, especially the larger ones, are insulated by a surrounding layer of fatty material called the _______________.

A cell that conducts electrochemical signals and is the basic unit of the nervous system is called a:

The _______________, or "lesser brain," is involved in remembering simple skills and acquired reflexes.

As Molly is walking across campus, a car swerves toward her. Her heart races and sweat breaks out as she jumps out of harm's way. This mobilization of energy is due to the action of Molly's:
