The nerves in your wrist, specifically the median and ulnar nerves, are located in specific areas that are crucial for hand and finger function.
Here's a breakdown of their locations:
-
Median Nerve: This nerve travels through the carpal tunnel, a narrow passageway formed by bones and ligaments on the palm side of your wrist. It provides sensation to the thumb, index finger, middle finger, and part of the ring finger.
-
Ulnar Nerve: This nerve passes through Guyon's canal (also known as the ulnar canal), located on the pinky finger side of the wrist. It provides sensation to the little finger and half of the ring finger.
Understanding the location of these nerves is important because compression or damage to them can lead to conditions like carpal tunnel syndrome (affecting the median nerve) or ulnar nerve entrapment (affecting the ulnar nerve), causing pain, numbness, and weakness in the hand and fingers.
