Carpal tunnel. In the human body, the carpal tunnel or carpal canal is the passageway on the palmar side of the wrist that connects the forearm to the hand. The tunnel is bounded by the bones of the wrist and flexor retinaculum from connective tissue. Normally several tendons from the flexor group of forearm muscles and the median nerve pass through it. There are described cases of variable median artery occurrence.
T o understand where the carpal tunnel is, look at your wrist with the palm of your hand facing up; as you flex your wrist toward yourself, the area beneath the wrinkles is the carpal tunnel. Through this tunnel are blood vessels, nerves and tendons.
