It is characterized by Flexor retinaculum. It curves over the carpal bones of the hands, covering them and framing the carpal passage.
The curve of the carpus alludes to a furrow in the front of the carpal bones. The flexor retinaculum of the hand ignores this furrow, changing over it into the carpel burrow. The middle nerve and the flexor ligaments go through the carpel burrow.
