Skeletal muscle and tendon microanatomy.Lieber, Richard LFridén, Jan
Skeletal muscles are anchored to bone, either directly or by a tendon. When the muscle contracts, the associated body part moves. This allows arms to lift, legs to run, and the face to smile. Most of these muscles are under the willful or conscious control of the brain. This type of ...
The vastus medialis originates from the lower intertrochanteric line, spiral line, and inserts into the medial quadriceps tendon and directly into medial patella. Its main function is to extend the leg the last 10%. Rectus femoris The rectus femoris is also one of the four quadriceps. It's ...

Calf Muscle Anatomy The calf is made up of two muscles, gastrocnemius and soleus. They work together to pull the foot downwards into plantarflexion e.g. pointing your toes or lifting your heel up off the floor. The deep soleus muscle arises from just below the knee joint. The gastrocnemius...
pelvis to just below the knee joint (the patellar tendon). The rectus femoris muscle is one of the fourquadriceps muscles. It is located in the middle of the front of the thigh. The other muscles of the quadriceps include the vastus medialis, the vastus intermedius, and the vastus ...
The junctional area is greatly enhanced by the interdigitation of cytoplasmic projections of the muscle cell and the collagenous fibers of the tendon. A basal lamina (B) coats the sarcolemma of the muscle cell. Actin filaments of the terminal sarcomeres (H) extend into the projections. 20,...
