Help studying for T.E.A.S. anatomy

How can I study for the science section of the T.E.A.S. without taking an anatomy/phiseology course beforehand? I feel like no matter how much I study the apps or study guides I'll never be able to answer all these super specific questions.

For example Which of the following is a sesamoid bone: The answer is patellae. How the hell am I supposed to know that? I'm taking a practice test and this is the first time I've heard of a sesamoid bone after putting in 40+ hours of T.E.A.S. studying. God damn.
