The cochlea is the sense organ that translates sound into nerve impulses to be sent to the brain. Each person has two cochlea, one for each ear. The cochlea is a fluid-filled, snail shaped cavern in the mastoid bone of your skull behind each ear. Tiny bones in the middle ear transmit sound from the eardrum across the middle ear and vibrate against the cochlea.
Harvard Medical School's website provides calorie expenditure estimates for weight training. A 30-minute weight-training session burns about 90 calories if you weigh 125 pounds. If you weigh 155 pounds, the same weight-training session will result in 112 calories burned. Aerobic exercises burn calories at a notably quicker rate than weight lifting.
