Accepted Answer

CT (Computed Tomography) scans and MRI (Magnetic Resonance Imaging) scans are imaging techniques used to create detailed images of the brain. They can show the location, shape, and size of brain structures, as well as identify abnormalities like tumors.

Question 7

Which of the following techniques produces the most detailed images of brain structures and allows any two-dimensional plane, or slice, of the body to be selected and displayed as an image on a computer screen?

Accepted Answer

MRI (Magnetic Resonance Imaging) scans produce the most detailed images of brain structures among the options listed. They use strong magnetic fields and radio waves to generate detailed images of the organs and tissues in the body. Unlike CT scans, which also produce detailed images but use X-rays, MRI can provide images in any two-dimensional plane without exposing the patient to ionizing radiation. ESB (Electrical Stimulation of the Brain) and EEG (Electroencephalography) are not imaging techniques; ESB is a method of stimulating brain regions electrically, and EEG measures electrical activity of the brain.

Question 8

Dissection reveals that the brain is made up of many anatomically distinct areas composed of clusters of neuron cell bodies interspersed by bundles of myelinated axons and pathways between those clusters. These clusters of neuron cell bodies are referred to as

Accepted Answer

Gray matter in the brain is composed of neuron cell bodies and is distinguished from white matter, which consists of myelinated axons. The limbic system and the subcortex are specific regions or structures within the brain, not terms describing clusters of neuron cell bodies.

Question 9

Clarence was in a car accident, and the doctor suspects that he may have suffered damage to his brain. He is put in a chamber with a strong magnetic field that will yield a three-dimensional picture of Clarence's brain. Which technique is being utilized?

Accepted Answer

MRI (Magnetic Resonance Imaging) uses a strong magnetic field and radio waves to create detailed images of the organs and tissues within the body, including the brain. This makes it suitable for detecting potential brain damage.

Question 10

Which of the following structural brain techniques may expose patients to unhealthy doses of radioactivity with repeated use?

Accepted Answer

CT scans expose patients to ionizing radiation, which can be harmful with repeated exposure. Ablations involve removing or destroying tissue, EEGs measure electrical activity, and MRI scans use magnetic fields and radio waves, none of which involve ionizing radiation.

Question 11

A specialized type of X-ray was used to show the area where a tumor was located within a patient's brain. This type of X-ray is known as

Accepted Answer

A computed tomographic scan (CT scan) uses X-rays to make detailed pictures of structures inside the body, including the brain, to locate tumors or other abnormalities.

Question 12

CT scans and MRI scans are considered __________ imaging techniques.

Accepted Answer

CT scans and MRI scans are primarily used to visualize the internal structures of the body, making them structural imaging techniques. They provide detailed images of bones, organs, and other tissues, but do not typically provide information about the function of these structures.

Question 13

The study of how biological processes, the brain, and the nervous system are related to behavior is called

Accepted Answer

Biopsychology is the field that examines the relationship between the brain, the nervous system, and behavior, focusing on how biological processes influence behaviors, thoughts, and feelings.

Question 14

Anatomists learned that the brain is made up of many distinct areas or "parts" by cutting apart autopsied human and animal brains and then examining them under a microscope. This procedure being used is known as

Accepted Answer

Dissection is the process of carefully cutting apart and separating the tissues of the body or parts of the body such as the brain, to study their structure and relationships. This method has been fundamental in understanding the distinct areas or parts of the brain through examination of autopsied human and animal brains.

Question 15

Dissection reveals that the brain is made up of many anatomically distinct areas composed of clusters of neuron cell bodies interspersed by bundles of myelinated axons and pathways between those clusters. These bundles of myelinated axons are referred to as

Accepted Answer

The bundles of myelinated axons in the brain are referred to as white matter, which contrasts with gray matter that consists primarily of neuron cell bodies. White matter is responsible for communication between different brain regions and between the brain and spinal cord.

Question 16

Using which brain tool is X-ray information collected by a computer from a number of different angles and then formed into an image of the brain to reveal the effects of strokes, injuries, tumors, and other brain disorders?
