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.
How Many Calories You Need To Lose Weight. Okay, so how many calories do I need a day to lose weight? Once you know how many calories you need to maintain your weight, you simply subtract some calories to put yourself into a caloric deficit. How many calories? Well, to lose roughly one pound of fat per week (a healthy goal) you need a 500-calorie-per-day deficit, he explains. In other words, just delete 500 calories from the number you found above. But a calorie deficit doesn't have to (and, in reality, shouldn't) come solely from eating less, says Valdez. Exercise can help, too.
