Parenchymal liver disease is any disease of the functional cells of the liver, as opposed to the bile duct cells or supporting cells. One example of a parenchymal liver diseas â¦ e is cirrhosis, in which the liver cells shut off and die.
Calf muscle strains can also developed due to repetitive overuse of the calf muscles usually with running and jumping, especially if the muscles are weak or tight. Pulled calf muscles are the most common cause of calf pain in runners.ther common terms for the condition include a calf muscle strain or torn calf muscle. Essentially, what all these terms refer to is when the calf muscles are pulled beyond their normal elastic limit, overstretching them and damaging some or all of muscle fibres.
The calf muscle (also called the gastrocnemius) is a commonly injured muscle. A pulled calf muscle most often occurs after vigorous activity (running, jumping, climbing stairs), but can happen with normal activity in middle-aged and elderly people.
