Printable skeletal muscle diagrams are available in this page. You can learn and download the muscle diagrams to help you study in your anatomy class. Let’s start studying the skeletal muscle structure and take a look at the following first muscle diagram below.
Notice in the skeletal muscle diagram above, that most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. The fibres and muscles are surrounded by connective tissue layers called fasciae. Muscle fibres, or muscle cells, are formed from the fusion of developmental myoblasts in a process known as myogenesis. Muscle fibres are cylindrical, and have more than one nucleus. They also have multiple mitochondria to meet energy needs. Check out more muscle diagrams in the images below.
Looking at the cross section of the muscle you can see bundles of fibres known as Fasciculi, which are surrounded by another connective tissue, called the Perimysium. Each Fasciculi contains anywhere between 10 and 100 muscle fibres, depending on the muscle in question. Skeletal muscle cells (fibers), like other body cells, are soft and fragile. The connective tissue covering furnish support and protection for the delicate cells and allow them to withstand the forces of contraction. The coverings also provide pathways for the passage of blood vessels and nerves.
