Exam 4: The Biological Mind the Physical Basis of Behavior

The _____ is the division of the autonomic nervous system associated with rest, repair, and energy storage.

Myelin, which insulates many neuronal axons, is formed by

The relationship between neurons and glia is similar to the relationship between

As part of the brainstem, the _____ is involved in maintaining balance and motor coordination; it is one of the first structures of the brain to be affected by alcohol .

The pons lies above the medulla and contains structures involved with the management of

Damage to the midbrain would most likely result in

Juan, a graduate student in an electrophysiology lab, stimulates an isolated neuron grown in a petri dish and measures its action potential. How will the neuron respond to the firing of the action potential?

Describe the functions of the sympathetic and parasympathetic nervous systems. Provide an example of an event (e.g., a close call on the highway, a relaxing evening in front of the fire, or deciding whether to take a new job), and describe how one or the other of the nervous systems is involved.

At the physical level, the brain is protected by all of the following EXCEPT

Elaine, a graduate student in a neuroscience department, is interested in understanding the effects of popular herbal remedies on neuronal communication. After growing neurons in a petri dish, she exposes the neurons to several common herbal supplements. After performing a series of electrophysiology experiments, she notes that one class of herbal supplements caused the neurons to become depolarized. What does this result mean?

Remarkably, Phineas Gage survived a horrific traumatic brain injury in 1848 but was not the same person as before his accident. Although outwardly normal in his intelligence, speech, and movement, Gage became prone to

The idea that a person's dominant hemisphere influences their creativity or ability to think logically is

Some individuals wash their hands repeatedly, unable to find relief from the thought that they are dirty or contaminated. This obsessive behavior may be related to a disorder of the

The depolarizing or hyperpolarizing current that results from neurotransmitter activity at the synapses of the receiving neuron drifts to the junction of the

Why is the primary motor cortex important for the control of movement?

Dave is asked a series of questions by a neuropsychologist such as, "Please describe the weather outside today." Speaking with ease Dave replies, "The traffic on the way to your office was awful, I could not use my airplane because it was stuck in the garage." In which area of his brain does Dave have damage?

Molly, a second-year neuroscience graduate student, treats neurons grown in a petri dish with drugs that "block" the function of neuronal receptors. What is a consequence of the drug treatment?

The endocrine system is comprised of a number of glands that release chemical messengers known as

Professor Freeman calls on his student Maya to describe how the presence of myelin affects an action potential. Maya should respond with which of the following statements?

_____ is a neurotransmitter that is found at the neuromuscular junction, in the autonomic nervous system, and in the central nervous system.
