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:
“The drama critic on your paper said my chablis-tinted hair was like a soft halo over wide set, inviting eyes, and my mouth, my mouth was a lush tunnel through which golden notes came.”
—Samuel Fuller (b. 1911)
