Skeletal muscle is a fascinating tissue with a complex structure it consists of elongated multinuclear cells called the myocytes (or myofibers) the muscle cells can be anything from 1 mm to 30 cm in length. Skeletal muscles skeletal muscles make up a big percentage of muscle mass in the human body ranging from 36 percent to 42 percent depending on the gender of the person with their attachment to the skeleton, these muscles have the ability to produce contractions and to move muscle components over large spans. Functional structure of skeletal muscle print reference this disclaimer: basic structure a skeletal muscle is made up of muscle and connective tissues, which both play a role in the contracting and function of the muscle biology essay writing service free essays more biology essays examples of our work biology dissertation examples.
Each skeletal muscle has three layers of connective tissue (called “mysia”) that enclose it and provide structure to the muscle as a whole, and also compartmentalize the muscle fibers within the muscle. The skeletal muscle’s main function is to move the bones of the skeleton this muscle is voluntary and is also striated, meaning that it is striped, which is due to the muscle fibers that are combined into parallel fibers. There are 3 types of muscle tissue:skeletal muscle tissue,cardiac muscle tissue, and smooth muscle tissue the structure of these muscle tissues can be described from the level of detail of the muscle fibres (muscle cells) through all the other muscle structures and parts of structures that bind muscle cells together enabling them to perform.
Although skeletal muscle cells come in different shapes and sizes the main structure of a skeletal muscle cell remains the same if you were to take one whole muscle and cut through it, you would find the muscle is covered in a layer of connective muscle tissue known as the epimysium.

Discuss how cellular structures, including the plasma membrane, specialized endoplasmic reticulum, cytoskeletal elements, and mitochondria, function together in the contraction of skeletal muscle cells. A bone is a structure that severs as a unit for the formation of this mass frame composed of hundreds of bones, called the skeletal system the skeletal system is composed of about two hundred and six bones in total.
