[Histonet] ImageJ : start help for muscle fiber count

[Tora Bardal]

Any guru out there that might give me some ideas how to measure size and number of muscle fibers in a cross section using ImageJ
Area by using freehand tool  works................. but I'm having problems making a threshold with the muscle cells outlined for automatic measurements.
 I'm not experienced, might be I haven't found the correct tool :-) Picture sample:
