 Muscle - Wikipedia, the free encyclopedia
Voluntary muscle contraction is used to move the body and can be finely controlled, such as movements of the finger or gross movements like the quadriceps muscle of the thigh.
Skeletal muscle or "voluntary muscle" is anchored by tendons to bone and is used to affect skeletal movement such as locomotion.
Deep muscles, superficial muscles, muscles of the face and internal muscles all correspond with dedicated regions in the brain.

 Upper Leg
This long muscle arises from a narrow point on the pelvis bone, passes between the masses of the hamstring and quadriceps groups and ends, at its wide apex, on the back of the femur.
The quadriceps muscles consist of: the rectus femoris, the vastus lateralis, the vastus intermedius, and the vastus medialis.
The muscle arises from the sacrum, passes through the sacrosciate foramen, and inserts as a round tendon into the upper edge of the great trochanter of the femur (upper edge of the thigh bone).

More properly, the patella may be regarded as a sesamoid bone, developed in the tendon of the Quadriceps; and the ligamentum patellæ, which is continued from the apex of the patella to the tuberosity of the tibia, as the proper tendon of insertion of the muscle, the medial and lateral patellar retinacula (see p.
Its fibers are directed downward and forward, and are chiefly attached to an aponeurosis which lies on the deep surface of the muscle and is inserted into the medial border of the patella and the Quadriceps femoris tendon, an expansion being sent to the capsule of the knee-joint.

 eMedicine - Deltoid Fibrosis : Article by Mark Brodersen, MD
Deltoid fibrosis has been associated with fibrous contractures of the gluteal and quadriceps muscles and is likely a similar process.
Pathophysiology: The deltoid muscle has 3 areas of origin: the clavicle, the acromion, and the scapular spine.
Deltoid fibrosis is a muscle disorder marked by intramuscular fibrous bands within the substance of the deltoid muscle.

 South Jersey Sports Online - Ask The Athletic Trainer! Archives
It is speculated that injuries are often caused by muscle fatigue, tight hamstrings, mineral imbalances, improper form, faulty posture, and an imbalance in strength between the hamstrings and quadriceps (muscle group in the front of the thigh).
It is true that of all the muscles in the body, the hamstring muscle group has nearly the highest incidence of strains.
The hamstring muscle group is comprised of three muscles, (Biceps femoris, semitendinosus, and semimembranosus) which work together to provide a variety of movements.

 UNIQUE ECCENTRIC ACTIVATION PATTERNS ARE OBSERVABLE ACROSS UNI- AND MULTI-ARTICULAR COMPONENTS OF QUADRICEPS FEMORIS
Despite the uni- vs. biarticular between-muscle differences and based on the common neural innervation, we hypothesized that the previously observed trends in activation level would be shown to be similar across quadriceps femoris components.
This suggests that the antagonist muscles were not an influential factor in the outcome of the study.
This study extended the experimental method to include analysis of the vastus medialis and biarticular rectus femoris muscles.
