PL-SQL: Cursor definition with additional parameter ? reason/meaning ?

I learned that a cursor definition in PL-SQL follows the schema:

Curosr mycurosr is ...

Now I found a couple of sample where the cursor definition is like

Cursor mycursor (somevar VARCHAR2) is ....

What does that parameter/variable defintion mean ? Sometimes even more 2 or 3 additional vars are defiend

How can I use this variable.
May I get an example on how to apply such a parameter.
