This is taken directly from-http://www.wisegeek.com/what-are-monocytes.htm#. Monocytes are a type of leukocyte or white blood cell which play a role in immune system function. Depending on a patient's level of health, monocytes make up between one and three percent of the total white blood cells in the body.
1 Ligamentum Patellae: It is attached above to the lower border of patella and below to the tuberosity of tibia. 2  In fact, this ligament is a continuation of the common tendon of the quadriceps femoris muscle containing the patella as a sesamoid bone. In fact, this ligament is a continuation of the common tendon of the quadriceps femoris muscle containing the patella as a sesamoid bone. 2  Medial Collateral Ligament: It is flat in form, attached above to the medial condyle of femur and below to the shaft of tibia.
However, this structure is really connecting the quadriceps muscle to the shin bone, and a tendon connects muscle to bone, and therefore patellar tendon is the more common description. The patellar tendon is an important part of the extensor mechanism of the lower extremity. The extensor mechanism includes the quadriceps muscle, quadriceps tendon, patella (kneecap), and patellar tendon. These structures function together to allow the knee to straighten, and can do so with significant force.
