"Q1. Describe the components, function and location of quadriceps femoris.!
#Rectus femoris, vastus lateralis, vastus intermedialis, vastus medialis!
#Knee extension!
#!
"Q3. Which of the quadriceps acts on the hip as well as the knee?!
#Rectus femoris assists in knee extension and hip flexion!
"Q4. Name the individual muscles that are collectively termed the hamstrings. What action
do they perform?!
#biceps femoris, semitendinosus, semimembranosus !
#Hip extension, knee flexion!
"Q5. Explain how the functional anatomy of the compartments change in the lower limb.
How does it reflect adaptation to bipedal posture?!
#flexion occurs in the anterior compartment in the upper limbs and thorax, flexion
occurs in the posterior compartment in the lower limbs!

Name the individual muscles that are collectively termed the hamstrings. Rectus femoris assists in knee extension and hip exion biceps femoris, semitendinosus, semimembranosus. Explain how the functional anatomy of the compartments change in the lower limb. How does it re ect adaptation to bipedal posture? occurs in the posterior compartment in the lower limbs. Exion occurs in the anterior compartment in the upper limbs and thorax, exion. Recall and list the movements of the thigh at the hip joint. Recall and list the actions at the knee joint. Which muscles help perform these actions? knee exion and medial lateral rotation knee extension quadriceps femoris knee extension muscle action knee exion muscle hamstrings action hip extension knee exion. Recall and list the actions at the ankle joint. Which muscles help perform these actions? muscle action.
