Exam 4: Cells of Thought

The neuropathology of multiple sclerosis is primarily characterized by:

The resting membrane potential of most neurons is approximately ____________________ millivolts.

A large collection of axonal fibers that connect regions within one hemisphere are called commissural fibers.

Neurotransmitters are stored within ____________________ in the presynaptic neuron.

In the peripheral nervous system clusters of gray cell bodies are called nuclei.

The change in membrane polarity that occurs prior to an action potential is called ____________________.

Which of the following statements is true?

The primary role of acetylcholine in the nervous system is at the neuromuscular junction.

The interaction of electrical and ____________________ processes is the basis of brain communication.

If substance X is a cholinergic antagonist,which of the following might you expect?

"Grey matter" refers to:

The communication of neurons is dependent on the passage of ions through the cell membrane.The four primary types of ions involved in this process are:

Norepinephrine is the most prominent neurotransmitter implicated in schizophrenia.

In the central nervous system clusters of gray cell bodies are called ____________________.

Collections of axons in the peripheral nervous system are referred to as:

Neurons communicate with one another by the action of neurotransmitters working within the space between neurons called ____________________.

The suggestion that all neural function is reflected in behavior and all behaviors have an underlying neural correlate has been called the cell hypothesis.

Can neurons heal or regrow if they die or are damaged? What has recent research shown about this?

Association fibers that connect regions within one cerebral hemisphere are:

Describe the resting potential and the process of the action potential.
