Us- in medical terminology is the masculine latin noun and is also a singular suffix for many words. It can be changed to -i to make a plural form of many words. For example: bronchus can be changed to bronchi.
This is not just a medical usage.
The suffix ~ac is used when an adjective is created from a noun, and is itself often used as a noun.
Medically, the first usage which springs to mind is "Cardiac Arrest" - this refers to the sudden stopping of the function of the heart...... cardiacus being Latin for 'heart'.
Another is the word sacroiliac, which means relating to the sacrum and the ilium (two of the bones in the pelvis).
The "-ac" is a suffix added mostly at the end of medical words and other scientific words that indicates "relation to". It comes from the French, Latin, and Greek forms and is sometimes related to the suffix "-ic" also. So, in a medical example we could take the word "cardiac". The "-ac" would mean "related to the heart". And so on. Here is a more detailed explanation: http://www.wordinfo.info/words/index/info/view_unit/5

Mnemonic using a very visual acronym story to recall -ar: "Does that car (-ar) really (relating to) belong (belonging to) to you?" asks the police officer who is trying to calm down the crowd. And no one thought you could teach your pet LioN (like, nature of) to drive your car. He's doing great but you forgot to teach him how to stop at stop signs and pedestrians.
