Question 1

The structure of a neuron,in terms of the shape of its axon and dendrites,

Accepted Answer

The structure of a neuron, including the shape of its axon and dendrites, remains flexible throughout life. This allows for neural plasticity, or the ability of the brain to reorganize itself by forming new neural connections in response to learning, experience, injury, or disease. Therefore, option D is the correct answer.

Question 2

Comparing neurons and glia,we find that __________ carry information to other cells;__________ are more numerous.

Accepted Answer

Neurons carry information to other cells, while glia provide support and protection to neurons. Neurons are actually more numerous than glia in the brain, but glia are more numerous in the entire nervous system.

Question 3

The single,long,straight fiber that extends from the cell body of a neuron and conducts impulses toward another neuron is called the

Accepted Answer

The axon is the long, straight fiber that extends from the cell body of a neuron and conducts impulses away from the cell body and toward other neurons, muscles, or glands. Dendrites, on the other hand, are short, branched fibers that receive signals from other neurons and transmit them to the cell body. Soma refers to the cell body of a neuron, and synapse is a junction between two neurons where signals are transmitted via chemical messengers called neurotransmitters.

Question 4

Question 5

Janet suffers from severe epileptic seizures that are untreatable with medicine.Her doctor decides to perform a callostomy (severing of the corpus callosum).Following surgery,her neuropsychologist conducts some tests to assess the effects of the surgery.During a divided visual field study,Janet is flashed words to both of her visual fields and asked to read the words.When some of the images are flashed,Janet experiences difficulty stating the word that was flashed.Explain which visual field presentation likely causes Janet the most difficulty when asked to state the word that was flashed and why.

Accepted Answer

The answer of Janet suffers from severe epileptic seizures that...

Question 6

The numerous short,widely branching fibers of a neuron that receive input from other neurons are known as

Accepted Answer

Dendrites are the numerous short, widely branching fibers of a neuron that receive input from other neurons.

Question 7

A/An __________ explanation would attempt to understand migration by examining mechanisms that produce migratory behavior whereas a/an __________ explanation would attempt to explain migratory behavior by understanding how that behavior has survived in the species over time.

Accepted Answer

A physiological explanation would attempt to understand migration by examining mechanisms that produce migratory behavior, such as hormonal changes or biological rhythms. An evolutionary explanation would attempt to explain migratory behavior by understanding how that behavior has survived in the species over time through natural selection and genetic changes.

Question 8

Neurons are cells in the nervous system that function to process information.Each neuron consists of three parts.Name and describe each of the three parts.

Accepted Answer

The answer of Neurons are cells in the nervous system...

Question 9

A glial cell is

Accepted Answer

Glial cells, also called neuroglia, are non-neuronal cells of the nervous system that provide support and insulation to neurons. They do not convey information like neurons do.

Question 10

A neuron is

Accepted Answer

A neuron is a specialized cell in the nervous system that transmits information to other cells in the body. Neurons are responsible for everything from simple reflexes like pulling your hand away from a hot surface to complex processes like learning, memory, and behavior.

Question 11

Cells in the nervous system that support neurons by insulating them and removing waste products are called

Accepted Answer

Glia cells, also known as neuroglia, are supportive cells found in the nervous system that perform a variety of functions including insulating neurons, providing structural support, and removing waste products. Mitochondria are organelles found within cells that are responsible for generating energy. Support cells and cell bodies do not accurately describe the specific type of cells being referenced.

Question 12

Where would you expect to find myelin?

Accepted Answer

Myelin is a fatty substance that covers and insulates the axon of a neuron. It helps to speed up the transmission of nerve impulses along the axon. Therefore, myelin is found covering an axon.

Question 13

The three parts of a neuron are the cell body,the __________,and the __________.

Accepted Answer

The cell body, dendrites, and axon are the three main parts of a neuron. The cell body contains the nucleus and other organelles necessary for the neuron's functioning. Dendrites receive information from other neurons and transmit it towards the cell body. The axon carries information away from the cell body towards other neurons or muscles. Glia refers to a type of supportive cells in the nervous system and is not one of the three main parts of a neuron. Action potential and membrane are not parts of a neuron, but rather processes and structures involved in the functioning of neurons.

Question 14

If a researcher wants to measure the electrical activity of the brain on a millisecond-by-millisecond basis,the best available technique would be ____________________.
or

Accepted Answer

The answer of If a researcher wants to measure the...

Question 15

The nervous system is made up of two types of cells called __________ and __________.

Accepted Answer

The nervous system is made up of two main types of cells: neurons (which transmit electrical signals) and glia (which provide support and nourishment to neurons). Therefore, option D is the correct choice as it includes these two types of cells.

Question 16

Question 19

Stimulants,depressants and narcotics are types of drugs that have varied effects on an individual.Briefly describe the effects associated with each class of drugs and give a specific example of a drug in each class (e.g.opiates).

Accepted Answer

The answer of Stimulants,depressants and narcotics are types of drugs...

Question 20

A single nerve cell,which sends and receives information,is called a

Accepted Answer

A neuron is the fundamental unit of the nervous system that sends and receives information. Glia refers to a group of non-neuronal cells that support and protect neurons, myelin is a fatty substance that coats some neurons to increase the speed of signal transmission, and the medulla is a part of the brainstem.
