In the asthi vaha srotas framework, Mula refers to which anatomical region?

• A. Hair and nails
• B. Skeletal system
• C. Cartilage and teeth
• D. Pelvic girdle and sacrum

Answer: (D)

In this framework, mula means the origin or root location of the channel governing that tissue. For asthi vaha srotas, which carry bone tissue, the foundational region is the bones that provide the central support of the skeleton—the pelvic girdle and the sacrum. This area serves as the structural base from which the bone-related channels arise and function, so it is identified as the mula. Hair and nails are peripheral manifestations linked to bone activity but not the primary root site of the bone-carrying channels. Cartilage and teeth are parts of the skeletal system, but they do not represent the root region for asthi vaha srotas in this framework. Pelvic girdle and sacrum best fit as the mula.
