gastrocnemius

Along with the soleus muscle, it forms half of the calf muscle. Its function is plantar flexing the foot at the ankle joint and flexing the leg at the knee joint

gluteus medius

During gait, these two muscles function principally in supporting the body on one leg, in conjunction with the tensor fasciae latae, to prevent the pelvis from dropping to the opposite side. Additionally, with the hip flexed the gluteus medius and minimus internally rotate the thigh.

bicep femoris

Function[edit] Both heads of the biceps femoris perform knee flexion. Since the long head originates in the pelvis it is also involved in hip extension. The long head of the biceps femoris is a weaker knee flexor when the hip is extended (because of active insufficiency).

soleus

Function[edit] The action of the calf muscles, including the soleus, is plantarflexion of the foot (that is, they increase the angle between the foot and the leg). They are powerful muscles and are vital in walking, running, and dancing.

peroneus longus

In human anatomy, the peroneus longus (also known as fibularis longus) is a superficial muscle in the lateral compartment of the leg, and acts to evert and plantar flex the ankle.

Adductor lonus

In the human body, the adductor longus is a skeletal muscle located in the thigh. One of the adductor muscles of the hip, its main function is to adduct the thigh and it is innervated by the obturator nerve

Aductor Magnus

The adductor magnus is a large triangular muscle, situated on the medial side of the thigh. It consists of two parts.

extensor digitorium longus

The extensor digitorum longus muscle is situated along the outside of the lower leg, just behind the tibialis anterior. It comes from close to the midline of the tibia and the shaft of the fibula. Its tendon divides into four parts as it passes over the front of the ankle.

gluteus maxiums

The gluteus maximus muscle is located in the buttocks and is regarded as one of the strongest muscles in the human body. It is connected to the coccyx, or tailbone, as well as other surrounding bones. The gluteus maximus muscle is responsible for movement of the hip and thigh.

gracilis

The gracilis muscle is one of the muscles found in the groin. It starts at the external point of the ischiopubic ramus (on the pubic bone) and extends down to the upper medial (middle) shaft of the tibia, or shinbone. The gracilis is responsible for hip adduction and assists knee flexion.

lliopsoas

The iliacus and psoas major muscles of the hip are so closely related in structure and function that they are often referred to as a single muscle, the iliopsoas.

rectus femoris

The rectus femoris muscle (/ˈrɛktəs ˈfɛmərᵻs/) is one of the four quadriceps muscles of the human body. The others are the vastus medialis, the vastus intermedius (deep to the rectus femoris), and the vastus lateralis. All four parts of the quadriceps muscle attach to the patella (knee cap) via the quadriceps tendon.

semimembranosus

The semimembranosus muscle is one of the three muscles that make up the hamstring. It is found on the back of the thigh and runs from the base of the pelvis (specifically the tuberosity of the ischium) to the back of the tibia, one of the bones that make up the lower leg.

semitendinosus

The semitendinosus muscle is one of three hamstring muscles that are located at the back of the thigh. The other two are the semimembranosus muscle and the biceps femoris. The semitendinosus muscle lies between the other two. These three muscles work collectively to flex the knee and extend the hip.

vastus lateralis

Vastus lateralis. The vastus lateralis muscle is located on the side of the thigh. This muscle is the largest of the quadriceps group (often called quads) which also includes the rectus femoris, the vastus intermedius, and the vastus medialis.

tibialis anterior

t also functions to 'lock' the ankle, as in toe-kicking a ball, when held in an isometric contraction. Antagonists are plantar-flexors of the posterior compartment such as soleus and gastrocnemius. Essentially, the movements of tibialis anterior are dorsiflexion and inversion of the ankle.

peroneus tertius

the peroneal muscles are a group of two muscles at the lower leg. They lie within the peroneal compartment located at the lateral fibular region. When lowering the foot they can be easily seen forming the surface of the lateral lower leg.

tensor faciae latae

he tensor fasciae latae is heavily utilized in horse riding, hurdling and water skiing. Some problems that arise when this muscle is tight or shortened are pelvic imbalances that lead to pain in hips, as well as pain in the lower back and lateral area of knees.[4]
