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.
Carpal tunnel syndrome is a painful progressive condition that occurs when the median nerve, which runs from the forearm into the palm of the hand and controls sensations to the palm side of the thumb and fingers, becomes compressed by a key nerve in the wrist to cause irritations and other swelling.
