Of the thirty descending *Dhamanîs*, ten (or five pairs) are conductors of blood, chyle, vital current, metabolic fluid, and lymph, and the remaining twenty are spinal nerves (specially the nerves of the sacro-coccygeal and sacral plexuses, if not also of the lumbar plexus). The obliquely branching *Dhamanîs*, so far as they are nerves, comprise the brachial and the lumbar plexus, and divide and sub-divide hundred-fold, thousand-fold, till they ramify into fibrillæ round the pores of the skin. They carry to the heart cutaneous sensations, external as well as internal. A fibril (सूक्ष्मनाड़ी) is said to be as minute as the thousandth part of a hair (लोम्नः सहस्रभागेन तुल्यासु प्रचरत्यणुः—*Panchadasî*).
