How to do core update with drush With which drush command can I update my Drupal 7.36 to 7.41?

I have tried so far the followings:


drush up drupal
drush pm-updatecode


But nothings has changed in either the code nor when I look at the currently pending updates.
Adi provided a good answer. So update the code with:

drush up drupal


But after that always preform database updates (if required):

drush updb
