Medium term notes dominate the front end of the credit yield curve?

[broadex]

The Curruculum says “medium term notes dominate the front end of the credit yield curve. What does it mean? I understand the part it says there are now less long term issues and more medium term maturities – but what is the front end / back-end???

front end - smaller maturity terms - while back end longer maturity terms.

By the way: medium-term notes don’t necessarily have what you would normally consider a medium-term maturity. They can have maturities of 9 months to 100 years.
