Unit 3 Flashcards
What is an EEG?
An EEG is an electrophysiological monitoring method to record electrical activity of the brain.
What is an EEG used for?
Used to help diagnose conditions such as seizures, epilepsy, head injuries, dizziness, headaches, brain tumors and sleeping problems. It can also be used to confirm brain death.
How are EEGs carried out?
Electrodes will be attached to your head and these wires are connected to an EEG recording machine. These tests last 20 to 40 minutes.
What can EEGs be used for?
They can be used to find diseases in your brain and confirm brain death.
What’s the difference between an EEG and an ECG

What is parkinson’s disease?

How can Parkinson’s disease be treated?
Treatments can be supportive therapies, medication or surgery for some people. you may not need any treatment during early stages but will during late stages.
What are lysosomes?
membrane-enclosed organelles that contain an different enzymes capable of breaking down different polymers.
How is action potential generated?
It is generated by a change in the ion concentrations across the cell membrane. The resting membrane potential is -60mV and the membrane potential is +40mV.
What are the three types of epithelial tissue?
squamous epithelium, cuboidal epithelium, and columnar epithelium.
