Human Cadaver Dissection: Week 2

Day 1: Fat trimming and isolation of the structures/ vessels around the female cadaver’s right foot/ ankle (malleoli). We identified the structures that run through the tarsal tunnel. Very tedious work.

Tarsal Tunnel – named for location anterior to posterior – from toward the toes back towards the heel: Tom, Dick, ANd Harry. T = Tibialis posterior D = Flexor Digitorum Longus A = Posterior Tibial Artery N = Tibial Nerve H = Flexor Hallicus Longus

Day 2: More fat trimming and cleaning up structures in the plantar surf of the right foot. Also very tedious work.


Then things got real exciting when we opened up the chest cavity – cut through the ribs then our instructor broke out a hammer and chisel and broke through the clavicle to lift up the rib cage then removed the heart and lungs. We trimmed the fat tissue away and cleaned out the dried blood from the cut away vessels of the heart and lungs. Located necessary vessels in the chest cavity.

Day 3: Today we opened up the abdominal cavity and took out some of the guts.

We went over the structures in the chest cavity.

Reviewed the structures for the second exam.
