Question 8

compare the masseter muscle in herbivores vs carnivores

carnivores: not as pronounced but still functional

Question 9

compare the temporalis muscle in carnivores vs herbivores

Answer 9

herbivores: not very prominent
carnivores: highly developed for vertical force and closure of the jaw (bite force)

Question 10

compare the pterygoide muscle in herbivores vs carnivores

Answer 10

herbivores: well developed to assist masseter muscle in lateral movements. The medial pterygoid helps in elevating the mandible, while the lateral pterygoid aids in moving the jaw forward and backward.
carnivores: less developed but still used in up and down motion of jaw
