Mastering Muscle Concepts:
1. Concept # 1: ____________________________________________________________________________________
2. # of attachments this muscle has _____
Does this muscle cross a joint? ______
3. Concept #2: _____________________________________________________________________________________
__________________________________________________________________________________________________
4. Concept #3: _____________________________________________________________________________________
5. What happens to the angle between your right thumb and index finger when you flex your left arm?
__________________________________________________________________________________________________
6. Concept #4: _____________________________________________________________________________________
7. Circle the correct answers. The humeral attachment is the (insertion / origin) and is (distal / proximal). While the
ulnar attachment is the (insertion / origin) and is (distal / proximal).
8. Concept #5: _____________________________________________________________________________________
__________________________________________________________________________________________________
9. Circle the correct answers. The brachialis is a(n) (flexor / extensor) because it (increase / decreases) the angel
between two bones.
10. If muscles can only pull, explain how can the arm is straightened from this angle? ____________________________
__________________________________________________________________________________________________
11. Circle the correct answers: The triceps brachii is a(n) (flexor / extensor) because it (increases / decreases) the angel
between two bones.
12. Concept #6: ____________________________________________________________________________________
__________________________________________________________________________________________________
13. Circle the correct answers. Flexors can typically be found on the (ventral / dorsal) side of the body while extensors
can be found on the (ventral / dorsal) side of the body.
14. Can a smooth, natural movement be produced when the biceps and triceps contract simultaneously? Why or why
not? _____________________________________________________________________________________________
__________________________________________________________________________________________________
15. Circle the correct answers. As you pull up on the table, your biceps are (contracted & hard / relaxed & soft) while
your triceps are (contracted & hard / relaxed & soft).
b) As you push down on the table, your biceps are (contracted & hard / relaxed & soft)
while your triceps are (contracted & hard / relaxed & soft).
16. Circle the correct answers. As you bend your knee, your hamstrings act as the (prime mover / antagonist) while your
quadriceps act as the (prime mover / anatomist).
b) As you extend your knee, your hamstrings act as the (prime mover / antagonist) while
your quadriceps act as the (prime mover / antagonist).
