Bacteria and viruses usually cause oral infections. They can affect the teeth, gums, palate (PAL-it, the roof of the mouth), tongue, lips, and inside of the cheeks.Simple oral infections are limited to the mouth and are different from oral lesions * , which are non-infectious and may be a sign of an illness that involves other parts of the body.hey can affect the teeth, gums, palate (PAL-it, the roof of the mouth), tongue, lips, and inside of the cheeks.

gastrocnemius - the muscle in the back part of the leg that forms the greater part of the calf; responsible for the plantar flexion of the foot gastrocnemius muscle skeletal muscle, striated muscle - a muscle that is connected at either or both ends to a bone and so move parts of the skeleton; a muscle that is characterized by transverse stripes
The gastrocnemius is one of the calf muscles, but attaches to the femur at the back of the knee, and runs down to attach to the calcaneus (heel bone) through the achilles tendon. It acts as a secondary knee flexor.his tendon continues below the patella to connect to the tibia. These muscles extend, or straighten, the knee. The hamstrings are the muscles on the back of the thigh. This muscle group is composed of the biceps femoris (outside), the semimembranosus, and the semitendinosus (inside).
