the hamstring (back of the thigh), the quadriceps (front), & the adductor (on the inside).

which of the following muscles serve as a common intramuscular injection site in infants?

the vastus lateralis

anterior lower limb muscles

tibialis anterior, extensor hallucis longus, extensor digitorum longus, fibularis tertius

movements of the thigh are accomplished by muscles anchord to the pelvic girdle

true

function of the iliotibial tract is to

provides stability to the knee and assists with flexion and extension of the knee

Hip extension and lateral rotation

34) The powerful flexors of the thigh are the

Iliopsoas

59) The gastrocnemius

Is a plantar flexor of the ankle and it inserts at the soleus

40) The muscles of the quadriceps femoris group insert on the

Tibial tuberosity

18) The muscle that originates on the entire length of the linea aspera is the

Vastis medialis, Biceps femoris

Which muscles are involved in dorsiflexion or plantar flexion

hallucis longus, the flexor digitorum longus as well as the tibialis posterior, gastrocnemius, the soleus and the plantaris, peroneus longus, and peroneus brevis

37) Biceps femoris, semitendonosus and the semimembranosus are all in the

hamstrings

23) The bond of collagen fibers that laterally brace the knee are the

iliotibial tract

inferior ramus of the pubis

muscles comprising the quadriceps include the

lateral rotators of the thigh: Piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and the obturator externus.

11) Adductor magnus, adductor brevis, and adductor longus are parts of the
