Step 4: Time to grill. Place the plank on the grill rack and allow it to preheat for about 5 minutes, or until it begins to crackle and smoke. Lay the salmon onto the plank, cover the grill, and allow the salmon to cook for 12 to 20 minutes, depending on its thickness. To test for doneness, insert a fork into the thickest part of the salmon.
1 The Spinal Cord-This is the part which carries information from the brain and transmits it to the rest of the body. 2  It can be viewed as the information superhighway of the body. 3  Medulla Oblongata-The part of the brain helps to control automatic functions like breathing, heart rate, digestion, etc.
The respiratory center consists of areas of the brain that are responsible for automatic control of breathing. Nerve cells in part of the lower brain stem, known as the medulla oblongata, initiate and set the rhythm of respiration. Another area of the brain stem, called the pons, contains nerve cells that affect the breathing rate. Nerve impulses travel from these areas to the respiratory muscles, causing inspiration and expiration.
