Responsiveness- is a property of all living cells- Muscle and nerve cells have developed this property to the highest degree. When stimulated by chemical signals‚ stretch‚ and other stimuli‚ muscle cells respond with electrical changes across the plasma membrane. b. Conductivity- Stimulation of a muscle cell produces

Anatomy of Knee The knee is composed of 4 bones: the femur‚ tibia‚ fibula and patella. Every one of these bones are practical in the knee joint‚ aside from the fibula. The patellar tendon elongates from the inferior pole of the patella‚ as an extension of the tendon of the quadriceps femoris muscle to the tibial tuberosity. The role of the patella tendon is to transfer the force of the quadriceps muscles‚ much like a rope around a pulley‚ as your knee straightens. (John Miller‚ 2015) Definition
