Muscle cell

Summary: Skeletal muscle cells are made up of long, fibrous protein filaments. These filaments are able to slide past each other, which shortens the cell. The main role of these cells is to contract, pulling the bones of the skeleton. This action results in movement. Tags: science student-book-7 biology Created: 2026-05-21 Last Updated: 2026-05-21
