Question 1

Where would you expect to find myelin?

Accepted Answer

Myelin is a fatty substance that covers axons, which are the long, thin projections of neurons responsible for transmitting electrical signals to other neurons or cells. Therefore, the most likely place to find myelin is covering these axons to help speed up the transmission of signals. Myelin is not typically found in skin cells or inside the nucleus of either neurons or glia.

Question 4

A glial cell is

Accepted Answer

Glial cells, also known as neuroglia, are cells in the nervous system that support and protect the neurons but do not directly participate in conveying information between cells. Examples of glial cells include astrocytes, oligodendrocytes, and microglia.

Question 6

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

Accepted Answer

The structure of a neuron, in terms of the shape of its axon and dendrites, is flexible throughout life. Neurons are capable of creating new connections with other neurons and changing the strength of existing connections, which allows for the plasticity and adaptability of the brain.

Question 7

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

Accepted Answer

The two types of cells in the nervous system are neurons and glia. Neurons are responsible for transmitting information throughout the body, while glia support and protect the neurons. Therefore, option D, glia and neurons, is the correct answer.

Question 8

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 non-neuronal cells in the nervous system that provide support and protection to neurons. They also insulate neurons by forming myelin sheaths around the axons and help remove waste products from the brain. Mitochondria are organelles found in all cells that produce energy through cellular respiration. Support cells and cell bodies are not specific enough to describe the type of cells that support neurons in the nervous system.

Question 9

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).

Question 12

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

Accepted Answer

Dendrites are the branch-like structures on a neuron that receive input from other neurons. Somas (or cell bodies) contain the nucleus and other organelles, but do not receive input like dendrites. Axons are the long, singular projections from a neuron that transmit signals to other neurons or cells. Glia are non-neuronal cells that support and protect neurons.

Question 13

A neuron is

Accepted Answer

A neuron is a specialized cell in the nervous system that is responsible for transmitting information to other cells. It is composed of various parts including the cell body, dendrites, and axon, all of which work together to facilitate communication between different neurons and other cells such as muscles or glands.

Question 14

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

Accepted Answer

The cell body, also known as the soma, contains the nucleus and other organelles. Dendrites are the branching extensions that receive information from other cells. The axon is the long extension that sends information to other cells. Therefore, the three parts of a neuron are the cell body, dendrites, and axon.

Question 15

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

Accepted Answer

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

Question 16

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 definition provided matches the description of an axon, which is the long, straight fiber that extends from the cell body of a neuron and conducts impulses away from the cell body towards other neurons or muscle cells. The other options listed are incorrect: soma refers to the cell body of a neuron, synapse is the junction between two neurons or between a neuron and its target cell, and dendrites are the short extensions that receive input from other neurons.

Question 17

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.

Question 19

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

Accepted Answer

Neurons carry information to other cells and glia are more numerous.

Question 20

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

Accepted Answer

A single nerve cell that sends and receives information is called a neuron. Glia are supportive cells that surround and support neurons, myelin is a substance that covers and protects the axons of neurons, and the medulla is a part of the brainstem involved in regulating vital functions such as breathing and heart rate.
