The anatomical neck is the one that looks like the neck from an anatomy point of view-it is between the head (that goes into the shoulder) and the tubercles.

The surgical neck is the site where most fractures occur. It comes just after the tubercles. Remember that the humerus is kind of in the shape of a "7" going into the shoulder joint, so the anatomical neck is like if you cut from the top with a knife, and the surgical neck is if you cut from the side.

It is the imaginary line between the end of the head of humerus and the starting point of shaft of humerus. Most commonly it fractures more than any other part of humerus. So it is called as surgical neck of humerus.

The surgical neck of the humerus is located just below the "head", and was named "surgical" because it is the most frequently fractured part of the humerus, and thus most visited by surgeons. If this area is broken, the nerve damage can cause loss of function of the affected arm.
