An electroencephalogram (EEG) is a test used to evaluate the electrical activity in your brain. Brain cells communicate with each other through electrical impulses. An EEG can be used to help detect potential problems associated with this activity. An EEG tracks and records brain wave patterns.An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.An electrocardiogram — abbreviated as EKG or ECG — is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart.

Which diagnostic test records the electrical activity of the heart?
An electrocardiogram (ECG) is one of the simplest and fastest tests used to evaluate the heart. Electrodes (small, plastic patches that stick to the skin) are placed at certain spots on the chest, arms, and legs. The electrodes are connected to an ECG machine by lead wires.
Which diagnostic test produces a three dimensional cross sectional view of the brain with or without a contrast medium?
CT scan is a non-invasive exam that combines the principles of x-ray with advanced computer technology to produce precise cross-sectional views of the internal organs and structures of the body.
How do you test brain function?
- Blood and/or urine tests.
- Imaging tests such as an x-ray or MRI.
- A cerebrospinal fluid (CSF) test. …
- Biopsy. …
- Tests, such as electroencephalography (EEG) and electromyography (EMG), which use small electric sensors to measure brain activity and nerve function.
What is used in processing biopsy specimens for laboratory examination?
This paraffin wax block with the embedded tissue is cut into very thin slices using an instrument called a microtome. These thin slices of the specimen are placed on glass slides, and dipped into a series of stains or dyes to change the color of the tissue. The color makes cells easier to see under a microscope.
Which of the following means an instrument for recording the electrical activity of the heart?
Electrocardiogram: (EKG, ECG): instrument which records the heart’s electrical impulses.

What is an EKG machine called?
Tthe importance of an electrocardiograph was recognized as being essential in diagnosing cardiac from non cardiac pain and able to help diagnose a myocardial infarction or a heart attack. Today we use a 12 lead electrocardiogram as a major tool in diagnosing heart disease.
What instrument is used for recording activity of the heart?
An instrument used to record the electrical activity of the heart. (Referred to as both ECG & EKG) The graphic representation of the electrical activity of the heart. An electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your heart.
What does an ECG measure quizlet?
What does an ECG measure? It measures the electrical conductive impulses of the heart muscle, allowing the physician to see any disturbances or disruptions in normal heart activity.

Which of the following is used to assess the electrical activity of a patient’s heart over a 24 hour period of normal activity?
Holter monitor: The electrical activity of the heart is typically recorded over a period of 24 hours. Three or four electrodes are attached to your chest, and a small recording device is worn on a belt or hung around your neck.
What is an MRI scan used to diagnose?
MRI has proven valuable in diagnosing a broad range of conditions, including cancer, heart and vascular disease, and muscular and bone abnormalities. MRI can detect abnormalities that might be obscured by bone with other imaging methods.
Which is better MRI or CT scan for brain?
Both MRIs and CT scans can view internal body structures. However, a CT scan is faster and can provide pictures of tissues, organs, and skeletal structure. An MRI is highly adept at capturing images that help doctors determine if there are abnormal tissues within the body. MRIs are more detailed in their images.
What does an MRI of the brain show?
A brain MRI can help doctors look for conditions such as bleeding, swelling, problems with the way the brain developed, tumors, infections, inflammation, damage from an injury or a stroke, or problems with the blood vessels. The MRI also can help doctors look for causes of headaches or seizures.
What is EEG test?
EEG brain activity
EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other seizure disorders. An electroencephalogram (EEG) is a test that measures electrical activity in the brain using small, metal discs (electrodes) attached to the scalp.
What is Neurodiagnostic test?
Specialized testing helps differentiate neurological conditions from other conditions with similar symptoms. Data from these tests helps our physicians determine an accurate diagnosis to begin appropriate treatment.
What is an example of a cognitive test?
Montreal Cognitive Assessment (MoCA): This test involves memorizing a short list of words, naming objects shown in pictures, copying shapes and performing other tasks. This test takes about 15 minutes to complete.
What is the inking method in gross examination?
Gross specimen examination. When a malignancy is suspected, then the specimen is often covered with ink in order to mark the margins of the specimen. Different colored inks can be used to identify different areas if needed. When sections are made and processed, the ink will mark the actual margin on the slide.
Why histopathology test is done?
Histopathology is the examination of biological tissues in order to observe the appearance of diseased cells in microscopic detail. Histopathology typically involves a biopsy, which is a procedure involving taking a small sample of tissue, usually undertaken by a pathologist, who are experts in diagnoses of diseases.

What is the name of the device used to record the impulses from the patient’s heart on paper?
The machine that records the patient’s ECG is called an electrocardiograph. The electrocardiograph records the electrical activity of the heart muscle and displays this data as a trace on a screen or on paper. This data is then interpreted by a medical practitioner. ECGs from healthy hearts have a characteristic shape.
What is the medical term for process of recording blood vessels?
Angiography (an-jee-OG-rah- fee. ) is the process of producing a radiographic (x-ray) study of the blood vessels after the injection of a contrast medium to make these blood vessels visible (angi/o means blood vessel, and -graphy means the process of recording).
