tonofilament[tonâ²Å-filâ²Ä-ment] 1. A structural cytoplasmic protein, of a class known as intermediate filaments, bundles of which together form a tonofibril; a tonofilament is made up of a variable number of related proteins, keratins, and is found in all epithelial cells, but is particularly well developed in the epidermis.
A given myofibril contains approximately 10,000 sarcomeres, each of which is about 3 micrometers in length. While each sarcomere is small, several sarcomeres added together span the length of the muscle fiber. Each sarcomere consists of thick and thin bundles of proteins referred to as myofilaments.
