Question

Unlike humans, cows eat all day. They spend hours and hours chewing with very little rest from the task in a 24-hour period. The food they eat (grass) is difficult to break down, requiring a lot of chewing. Understanding the endurance required for these chewing muscles, what fiber type would you expect to be predominant in their chewing muscles?

Answer 1

Masseter Muscle Fibers

Step-by-step explanation:

The process of chewing of food to break it into smaller pieces is called Mastication. There are various types of muscle fibers that help in the process of mastication but in case of herbivorous animals like cows, large strong masseter muscles are predominantly found. These muscles raise the lower jaw by elevating the mandible during chewing. These muscles are so powerful and found in the cheek area in both sides of the face and are thus called left and right masseter muscles.
