There are many components of skeletal muscle anatomy. However, skeletal muscle is primarily made of muscle fibers, which are bundles of lots of proteins called myofibrils. Each myofibril contains smaller protein structures called sarcomeres. These have light and dark areas and create patterns of red...

Skeletal muscle is one of the three significant muscle tissues in the human body. Each skeletal muscle consists of thousands of muscle fibers wrapped together by connective tissue sheaths. The individual bundles of muscle fibers in a skeletal muscle are known as fasciculi. The outermost connective ...
Skeletal muscle is enclosed in connective tissue scaffolding at three levels. Each muscle fiber (cell) is covered by endomysium and the entire muscle is covered by epimysium. When a group of muscle fibers is “bundled” as a unit within the whole muscle by an additional covering of a conn...
The sarcomere is the functional unit of the muscle fiber. The sarcomere itself is bundled within the myofibril that runs the entire length of the muscle fiber and attaches to the sarcolemma at its end. As myofibrils contract, the entire muscle cell contracts. Because myofibrils are only approxim...
Thus, skeletal muscle weakness associated with spaceflight can result from muscle fiber atrophy and segmental necrosis, partial motor denervation, and disruption of the microcirculation.doi:10.1096/fasebj.4.1.2153085D.

A skeletal muscle is made up of skeletal muscle fibres bound together by various layers of connective tissue that support extensive networks of nerves and blood vessels and form tendons and aponeuroses. From: The Pocket Podiatry Guide: Functional Anatomy, 2009 ...
