Exam 4: The Biological Mind the Physical Basis of Behavior

Compare and contrast the function and source of neurotransmitters and hormones.

Which of the following is an accurate match between a division of the autonomic nervous system and a bodily function or state?

A well-known local herbalist sells the neurotransmitter gamma-aminobutyric acid (GABA)as "the body's natural tranquilizer," stating that it helps to calm the central nervous system and prevent anxiety and stress-related messages from reaching the motor centers of the brain.This portrayal reflects GABA's ____.

Lower than normal levels of hormones released from the ____,which raises or lowers metabolism,can mimic the symptoms of ____.

The brain and the spinal cord form the ____.

Which of the following is an example of the autonomic nervous system at work?

Psychologists have described the human nervous system as the communication and control center for the body.The nervous system allows us to take in information from the environment,communicate the information to different parts of the body,and coordinate the body's response.The nervous system itself is made up of neurons,or nerve cells,that communicate with each other by receiving and transmitting electrochemical signals,called neurotransmission.All human behavior is made possible by the activity of individual neurons working together in the nervous system.Think about a simple action you do every day,like answering your phone.When you perform this routine act,what are the individual neurons in your nervous system doing to make it possible? In a multiparagraph essay,explain how the activity of individual neurons enables you to perform a simple action like answering your phone.Be sure to describe the main parts of a neuron,explain the unique function of each part,and describe how neurons use electrochemical signals for neurotransmission.Include details from class materials,readings,and research on the nervous system to support your discussion.

The ____ is a part of the prefrontal cortex located right behind the eyes that participates in our emotional lives.

Abby,a graduate student working in a neuroscience lab,grows neurons in a petri dish to study the effects of environmental toxins on neuronal communication.During one of Abby's experiments,she accidentally damages the axon of a neuron.What will be an immediate consequence of this mishap?

The ____ lobe is the most forward of the four lobes of the cerebral cortex.It is the location of the primary motor cortex and some of the most complex cognitive processes.

Marcus,who works in the laboratory of Dr.Flores,a prominent electrophysiologist,takes readings with a recording electrode placed within a squid axon.He reports to Dr.Flores that the cell is firing an action potential.What measurement did Marcus take with the recording electrode?

Stefan is ____;therefore,he is nearly certain to lateralize language to his left hemisphere.

Tomas,age 15,experienced a severe head injury and his prefrontal cortex was damaged by the trauma.Tomas now has difficulty with

What is the major function of the spinal cord?

How do drugs classified as "SSRIs," such as Prozac,alter neuronal communication?

A rare health condition caused damage to the amygdala on both sides of Nina's brain.She is now more likely than most people to ____.

When a specialized function of the cerebral cortex occurs on either the right or the left hemisphere,this is referred to as ____.

Damage to which part of the brain would result in death due to the loss of heart function and blood pressure regulation?

How do dendrites facilitate neuronal communication?

The ____ lobe in the cerebral cortex curves around the side of each hemisphere and is the location of the primary ____ cortex.
