(1 point)
bone densitometry
arthroscopy
electromyography
myelography

Explanation:

• Bone densitometry: Measures bone density, not muscle signals.
• Arthroscopy: Examines joints, not muscle - nerve communication.
• Electromyography (EMG): Records electrical activity of muscles to assess muscle function and nerve - muscle communication.
• Myelography: Visualizes spinal cord and nerve roots, not directly muscle strength in the arm related to signal reception.

Answer:

electromyography
