In your study material you have given this wrong information. (spinal cord is about 43 cm long in adult women and 25 cm long in adult men), its actually 45 cm for men and 43 cm for women. i could find so many wrong information next one i noticed there are 3 bones each in both legs and hands , if you mention long bones , then it will be correct .... how can you make such silly mistakes. ? please provide correct information , dont mislead kids.
