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 deep muscles of the posterior compartment of the leg are the popliteus, tibialis posterior, flexor digitorum longus and flexor hallucis longus. The gastrocnemius calf muscle is the most superficial of the calf muscles. It inserts onto the heel bone via the Achilles tendon. The gastrocnemius muscle flexes the foot at the ankle joint â that is it acts to point the foot downwards by bending it at the ankle joint, such as when you stand on your toes. This action is known as plantar flexion. The gastrocnemius also flexes the leg at the knee joint.
