The thorax, abdomen, and pelvis are (together with the back) parts of the trunk. The thoracic and abdominal cavities are separated from each other by the diaphragm. The abdominal cavity proper and the true pelvic cavity are continuous across the plane of the pelvic inlet, or brim (see fig. 31-3).
Preheat oven to 350. Heat a medium ovenproof nonstick skillet over medium-high heat. Add olive oil. Pat salmon dry with paper towels. Season the flesh-side of the salmon with salt. When the oil is hot, add salmon skin-side down. Sear until the skin is golden brown and crispy, about 5 minutes. Turn and transfer to oven and cook until a cake tester or tip of a paring knife is just warm to the touch when inserted into the middle of the salmon; about 5 minutes for medium-rare and 9 minutes for fully cooked through.
Set the salmon fillet on top of the dill and sprinkle with salt and pepper. The layer of lemon and dill will add fragrance to the fish as it cooks. Bake the salmon in the oven for 25 to 30 minutes, depending on the thickness of the salmon fillet. To determine when the salmon is cooked, insert a sharp kitchen knife into the thickest part of the fillet and pull it to one side. The fish should appear cooked through and no longer be translucent.
