4. Avascularity. Epithelial cells DO NOT have ANY blood vessels but they are inverted (meaning they have a nerve supply) aka they have nerves-the epithelial tissues get their oxygen and nutrients from the blood vessels with in the connective tissue that underlies the epithelium.
Prepare the grill for direct grilling at 500ÂºF. once hot, clean the grill surface with a sturdy grill brush. For filets that are 1-inch thick, we grill the salmon for a total of about 8 minutes over a 500ÂºF fire. This should result in fish that is cooked medium to medium-well. Place each filet on the grill grate directly over the fire with the skin-side up. After about 5 minutes, the edges of the meat should begin to pull away from the grill. The salmon will release from the grill when it is ready to turn over. A few exploratory lifts at the edges should tell you whether or not it is ready.
Cook the fish for 4 to 6 minutes and then turn to grill on the other side for approximately same amount of time. Insert the tip of a knife in thickest area of the fish to check for doneness. The meat should be flakey and opaque in appearance. The internal temperature of the fish should be at least 145Â°F.
