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 middle compartment of the deep plane of the palm. The tunnel consists of bones and connective tissue. Several tendons and a nerve pass through it.
The canal is narrow and when any of the nine long flexor tendons passing through it swells or degenerates, the narrowing of the canal often results in the median nerve becoming entrapped or compressed, a medical condition known as carpal tunnel syndrome.
Famous quotes containing the word tunnel:
“You may raise enough money to tunnel a mountain, but you cannot raise money enough to hire a man who is minding his own business.”
—Henry David Thoreau (1817–1862)
