Explanation:

• For question 17:
• EKG (electrocardiogram) or ECG (electrocardiography) is a test that records the electrical activity of the heart.
• The electrical activity in the brain is recorded by an EEG (electroencephalogram).
• The electrical activity in the spinal nerves and skeletal muscle is not what EKG/ECG records.
• For question 18:
• Sub/luxation is defined as a partial joint dislocation.
• Vertebral rupture is a break in the vertebrae.
• Joint compression is the squeezing of a joint.
