Median Nerve: What Is It, Anatomy, Function and Common Conditions

Q: What is the function of the median nerve?

The median nerve performs both motor and sensory functions in the upper limb. It innervates muscles responsible for flexing the wrist, fingers, and thumb, allowing us to perform gripping and grasping movements. Additionally, it provides sensory innervation to the thumb, index finger, middle finger, and half of the ring finger, allowing us to perceive touch, pressure, and temperature in those areas.

Q: What conditions affect the median nerve?

The median nerve can be affected by various conditions, including: Carpal tunnel syndrome Pronator teres syndrome Anterior interosseous nerve syndrome

Q: How is carpal tunnel syndrome diagnosed?

Carpal tunnel syndrome is diagnosed through a combination of clinical evaluation and tests. A healthcare professional will examine the hand, wrist, and arm, assessing for symptoms and performing specific tests to evaluate the median nerve's function.

Q: What are the treatment options for median nerve-related conditions?

The treatment options depend on the specific condition and its severity. Conservative approaches may include rest, immobilisation, splinting, physical therapy, and anti-inflammatory medications. In more severe cases, corticosteroid injections or surgical intervention, such as carpal tunnel release, may be necessary to relieve pressure on the median nerve.
