The What's-Worth-Knowing
Questions Curriculum
1. Why do we associate the heart with love? Why do we use terminology like "having your heart broken" or "having your heart ripped out"?
2. What is responsible for the pounding sound in your chest? What actually makes the noise?
3. Why are my hands and feet always cold at football matches?
Circulatory System II
Mammalogy
1. What is the relationship between diet and tooth morphology?
2. Is there a relationship between diet and body size? What is the largest insectivorous mammal?
3. Do dogs and cats differ in bite force? Is jaw shape related to bite force?
What factors are involved in the relative bite forces between dogs and cats ?
Possible Answers
Hypothesis
Cats and dogs differ in the relative size of the temporalis muscle

The relative position of the carnassial pair may differ between cats and dogs

Maybe it's related to the animal's diet
Animals with larger temporalis muscles will have stronger bite forces

Animals with carnassials located close to the jaw articulation joint will have stronger bite forces

Hypercarnivores will have stronger bite forces than omnivores
Calculating Maximum Estimated Bite Force (MEBF)

The following formula is derived from a version of Thomason’s (1991) to estimate the maximum bite force. This formula estimates the maximum bite force by using the cross-sectional area of the muscles and multiplying them by 300 Mpa, the average force per area of a muscle. You will use your data achieved from measuring the images in order to calculate the MEBF for the species of interest. The formula gives MEBF in Newtons (N).

MEBF=[(M*m)+ (T*t)]/Lj

M = area of the masseter/pterygodial muscles in cm2 multiplied by 300 Mpa
m = length of masseter moment arm in cm
T = area of the temporalis muscle in cm2 multiplied by 300 Mpa
t = length of temporalis moment arm in cm
Lj = length of the lower jaw in cm
