Lab 3 – Skeletal Muscle Physiology Introduction Skeletal muscles are composed of hundreds to thousands of individual cells‚ each doing their share of work in the production of force. As their name suggests‚ skeletal muscles move the skeleton. Skeletal muscles are remarkable machines; while allowing us the manual dexterity to create magnificent works of art‚ they are also capable of generating the brute force needed to lift a 100-lb. sack of concrete. When a skeletal muscle from an experimental

Abstract Introduction The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint‚ while the distal part of the femur articulates with the tibia and kneecap forming the knee joint. By most measures the femur is the strongest bone in the body. The femur is also the longest bone in the body.Using the AP view of the hip‚ angle formed by axis of femoral shaft and line drawn along axis of femoral neck passing through center of head of femur. At birth‚ the femoral neck
