What are the various files that could have PATH declarations for OS X Terminal in them?

export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"

PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin:/usr/local/git/bin"

/etc/paths.d/
/etc/manpaths.d

$ cat /etc/paths
/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin
