Again, it really varies from team to team. The beauty of the University having SUCH a hierarchical structure is that almost everyone is a manager. You will always be sitting near someone who is, in which case you do have a lot of access to managers. That being said, your manager might be too low-level to answer/assist in your question, in which case you need to find THEIR manager, which can be harder if they don't even sit in the same office or are always running off to meetings. My last supervisor was great for providing praise/recognition, but was not a good mentor/role model. However, while HER supervisor wasn't great with praise/recognition, he was a good mentor/role model. Sometimes you can't get what you need from one manager, but take a bit from multiple managers. The problem exists when you have to worry about going over one manager's head, or if you only have one manager...
