To find the answer to this question, we can look at the anatomy of the human head and neck. The muscles responsible for chewing movements or mastication are located in the jaw area.
One way to determine the number of muscles involved is to count the pairs of muscles on each side of the jaw.
A pair is formed by two corresponding muscles, one on each side of the body. To chew effectively, muscles on both sides of the jaw work together.
So, let's count the pairs of muscles involved in chewing movements:
Starting from the top, there are two major muscles involved: the temporalis muscle and the masseter muscle.
The temporalis muscle is located on the sides of the head, just above the ears. It helps with jaw movement and closing the mouth.
The masseter muscle is the primary muscle responsible for chewing. It is the large muscle that you can feel when you place your fingers on your cheek and bite down. It is one of the strongest muscles in the human body.
So, we have identified two pairs of muscles so far (temporalis and masseter on each side).
Based on this information, the correct answer to the question is A. Two pairs.
