Dissection of posterior aspect of left thigh
Popliteal fossa, close-up view
The lower part of the dissection illustrated in view 182-6 is shown in this photograph. Adipose tissue has been removed from the popliteal fossa. The hamstring muscles (3, 8, 9) have been separated from each other to expose the sciatic nerve passing into the fossa from above. Reference should be made to view 182-5 for the superficial dissection of this area and to views 183-5 and 190-2 for deeper dissections.
