Zero addresses on a 255.255.0.0 mask

I'm dealing with a large network with a 255.255.0.0 subnet mask. Lets say 10.1.0.0 with 255.255.0.0 mask; so that gives me from 10.1.0.0 to 10.1.255.255 for addresses. Now I know that using 10.1.0.0 as a static IP is a no-no, but what about the other zero addresses (e.g. 10.1.44.0)?

Same goes for the 255 addresses. 10.1.255.255 should be the broadcast address but what about the rest that end in 255 (e.g 10.1.77.255)?

The other zero addresses are OK to use. It is only the first and last address in a network or subnet that is reserved.

The relevant paragraph is the one just before the "Sample Problem" section.
