Question

1. an electroencephalogram records electrical activity in the:

○ brain
○ heart
○ muscles
○ skin

1. what is a sudden traction on a muscle, ligament, and joint capsule?

○ sprain
○ strain
○ dislocation
○ subluxation

Explanation:

Question 13

An electroencephalogram (EEG) is a test that measures electrical activity in the brain. The heart's electrical activity is recorded by an electrocardiogram (ECG), muscles have electromyograms (EMG) for their electrical activity, and the skin does not have this type of electrical activity recording related to EEG. So the correct option is the one related to the brain.

A strain is defined as a sudden traction (stretching or tearing) on a muscle, tendon (which connects muscle to bone), or in some definitions can involve ligaments and joint capsules due to overstretching. A sprain is an injury to a ligament (connecting bone to bone). Dislocation is the displacement of a bone from a joint, and subluxation is a partial dislocation. So the term for sudden traction on muscle, ligament, and joint capsule is strain.
