I just recieved a really great job offer not sure of the benefits?

Okay the benefits that come with the job are Medical, Dental, 401k, Health Care Spending Account, Family Care Spending Account, Short-term, and Long-term disability, Employee Assistance, and a couple others. So my question is What is a Health Care Spending Account, a Family Care Spending Account, and Employee Assistance? I mean, what do those 3 do for me?
