question on sign notation, small arrow heads

[Anne-Claude Prélaz Girod]

dear Val,

I' m not sure about how to write the movement of the sign /ESTOMAC/
  http://www.pisourd.ch/index.php?theme=dicocomplet          --->  
estomac (stomach)....

how should one position the small arrows heads... in the lessons (on  
the net)  the arrow pointing down means closing... and the arrow  
pointing up means opening..... but I'm not sure it's used this way !!

can you tell me if the way I wrote this sign is correct.... (if I  
follow the lessons... the small arrow heads on top point down for  
closing) but i'd rather write it
and

could you explain the arrow heads... and give some example on when to  
use which...
Thanks

Anny
