Question 20

In the depicted image, the patient’s position would result in active insufficiency of the:

hamstrings
quadriceps
tibialis anterior
soleus

Answer 20

hamstrings

Question 21

Which muscle actively contributes to producing a tenodesis grip?

flexor digitorum profundus
extensor digitorum
palmaris longus

inguinal ligament
adductor longus
sartorius
iliotibial band
