GROSS ANATOMY

Detailed explanation-1: -popliteus bursa: between popliteus tendon and posterior tibia and fibula; communicates with the synovial cavity.

Detailed explanation-2: -They are the: prepatellar, infrapatellar, suprapatellar, Pes Anserine, and the semimembranosus bursae. The prepatellar bursa is located in front of the knee cap.

Detailed explanation-3: -The suprapatellar bursa is located between the quadriceps tendon and the femur. Failure of regression of the transverse septum formed in embryonic life between the suprapatellar plica and the knee joint fluid leads to the formation of this bursa.

Detailed explanation-4: -The bursa communicates with the knee joint in most adults and thus is sometimes referred to by many as a recess, being comprised of a distal gastrocnemius bursa and a proximal semimembranosus bursa, which sometimes are partially separated by a septum.
