Muscle ID quiz 3

Gluteus medius

Buttock muscle on the side of the pelvis. Important for walking, abduction of the thigh, and external rotation of thigh.

Gluteus Maximus

Large, superficial muscle forming the buttocks. Spans from pelvis down to femur. Responsible for hip flexion, standing, and rotation of thigh.

Adductor magnus

The triangular muscle on the medial side of the thigh. Brings legs together, push legs back, pulls hips in medially, and walking.

Bicep femoris

A long muscle on the outer side of the back of the thigh. Crucial for bending legs, moving the thigh back, laterally rotating the lower leg, and internal/external rotation of the knee joint.

Semitendinosus

Between the biceps femoris and the semimembranosus. Functions include flexing the knee, extending hip, and moving thigh backwards

Semimembranosus

Deep, large hamstring muscle. Extends the hip, flexes the knee, and rotates knee.

Gastrocnemius

Forms the bulk of the calf and runs from the knee to the heel. Helps with plantar flexion, knee flexion, running, and jumping.

iliotibial tract

Located on the side of the thigh running from the hip down to the knee. Provides stability in the hip and knee as well as the femur on the tibia during walking, running, and standing. Movement in the lower leg.

Soleus

Located deep in the calf, beneath the larger gastrocnemius, running from the tibia to the fibula down to the heel. Helps with plantar flexion, walking, running, and balance.

Calcaneal

Located on the back of the foot or heel. Supports body weight, provides leverage for the lower calf, helps with running, walking, jumping, and plantar flexion. Flexes and extends the foot.

Sartorius

A long muscle running from the hip bone to the medial side of the shin (tibia). Flexes and rotates the hip as well as bend the knee.

Gracilis

A long muscle located on the medial side of the thigh from the pubic bone to the tibia. Abduction of legs, knee flexion, and medial rotation of the tibia on the femur.

Rectus femoris

Superficial muscle in the middle of the front of your thigh, running from the hip bone to the kneecap and shin bone. Functions include knee extension, hip flexion, and stabilizing the hip.

Vastus medialis

The thigh muscle on the medial front of your thigh. Runs from the femur to the patella. Provides stability in the kneecap, extends the knee joint, steightens leg movement for walking, running, and standing.

Extensor digitorum longus

The muscle in the front of your lower leg. Adjacent to the tibialis anterior. Important for dorsiflexion and extension of the ankle.

Adductor longus

Long, triangular muscle in the medial part of the thigh. Goes from the pubic bone to the knee. Functions include hip adduction, hip flexion, and medial rotation of the thigh.

Vastus lateralis

The largest muscle in the thigh is located on the lateral side of the thigh. Helps with knee extension, straightening legs, and getting up from squatting.

Tibialis anterior

The upper portion of the lateral tibia runs to the metatarsals. Helps with dorsiflexion and inverts foot.
