Counting the vessels (dhamanī) and related structures

Twenty vessels (dhamanī) run from the navel, ten upward and ten downward, and four run crosswise, making twenty-four; there are sixteen kaṇḍarās (thick tendons) and six kūrcas. A footnote cites Suśruta for the same twenty-four and explains that 'all around' in the verse should be read as upward and downward only, since the four crosswise vessels are named separately.
