When chewing do the upper teeth grind the food more or the lower ones?

Question

hint: take gravity into account

Answer 1

Mastication or chewing is the process by which food is torn and/or crushed by teeth. It is the first step of digestion and it increases the surface area of foods to allow more efficient break down by enzymes. As chewing continues, the food is made softer and warmer, and the enzymes in saliva begin to break down carbohydrates in the food.

After chewing, the food (now called a bolus) is swallowed. It enters the esophagus and continues on to the stomach, where the next step of digestion occurs.

Mastication is chiefly possible thanks to powerful muscles, masseter and temporalis, as well as smaller muscles that allow fine control. They move the mandible against the upper jaw and enable crushing of relatively hard food.

In humans, the mandible is connected with the temporomandibular joint that permits forward-backward and side to side movement.

Some animals, called ruminants, chew food more than once. These animals, such as cows, chew their food more than once for the extra nutrients in it. This food is called cud.

Answer 2

Waise to it is teamwork but as u r asking out of the two which works the most the answer would probably be the lower teeth, as u know the lower jaw can move and the upper jaw cannot, so it is obvious that the lower jaw plays a gr8er role in chewing.

Answer 3

Its the lower jaw that moves while we eat, so technically the lower teeth grind the food more....... But actually, the lower teeth need something to grind the food against, and thats where the upper teeth come into play.So, this way , both upper and lower teeth contribute equally to the grinding process.

Answer 4

Same. Physics says that action equals reaction, so you can't have teeth on one side, say the top, grind more than teeth on the other side, say the bottom.

Where there is a difference, as you probably know, is between the front and back teeth, the front teeth cut but don't grind, and the back teeth grind but don't cut.

Answer 5

Hi! Actually lower jaw plays important role in chewing. You know, lower jaw is only part in our skull that can move i.e movable. Rest all are fixed. So while we eat or speak lower jaw only moves not upper jaw.So lower jaw helps in grinding more, than the upper jaw.
Chew well!

Answer 6

the process of grinding takes placed only when the upper and the lower teeth meet. so its no meaning in asking which grinds food more

Answer 7

Lower

Answer 8

Upper

Answer 9

The lower. When u chew, notice which is have the greatest movements. The upper jaw does not move, its the lower one with the greatest movement and churning

Answer 10

the comparable element occurred to my Guinea Pig. We bought right here marvelous animal blocks for her to chew on through fact interior the wild rabbits and guinea pigs placed on their tooth down needless to say yet in a house they have not got any thank you to grind down their tooth. We additionally gave her a good number of carrots and it helped.
