Question

drag the items from the bottom to the slots on the right.

plantar flexion
tibialis anterior
hamstrings
quadriceps femoris

knee extension
dorsiflexion
gastrocnemius
knee flexion

Explanation:

Match Plantar flexion to its muscle

Using the Muscle Actions knowledge point
Plantar flexion is the action of pointing the toes downward. The primary muscle responsible for this action among the choices is the gastrocnemius.

• Action: Plantar flexion
• Muscle: Gastrocnemius

Match Tibialis anterior to its action

Using the Muscle Actions knowledge point
The tibialis anterior muscle is located on the anterior aspect of the lower leg. Its contraction pulls the top of the foot upward toward the shin.

• Muscle: Tibialis anterior
• Action: Dorsiflexion

Match Hamstrings to their action

Using the Hip Muscle Functions knowledge point
The hamstring muscle group (located on the posterior thigh) crosses both the hip and knee joints. Its primary action at the knee joint is flexion.

• Muscle: Hamstrings
• Action: Knee flexion

Match Quadriceps femoris to its action

Using the Muscle Actions knowledge point
The quadriceps femoris muscle group (located on the anterior thigh) is the primary extensor of the knee joint.

• Muscle: Quadriceps femoris
• Action: Knee extension

Answer:

Left Item	Right Slot (Matched Item)
Tibialis anterior	Dorsiflexion
Hamstrings	Knee flexion
Quadriceps femoris	Knee extension
