Muscle cells are highly specialized, each optimally designed to perform its required function, and there is variation amongst muscle cells within each category. There are three different types of muscle cells in the human body: skeletal, smooth and cardiac.
Diagram of the Structure of a Muscle Cell (also called a muscle fibre). The structure of a muscle cell can be explained using a diagram labelling muscle filaments, myofibrils, sarcoplasm, cell nuclei (nuclei is the plural word for the singular nucleus), sarcolemma, and the fascicle of which the muscle fibre is part. The structure of muscle fibers is included in courses in human biology and ...
A single muscle cell contains many nuclei, which are pressed against the cell membrane. A muscle cell is a long cell compared to other forms of cells, and many muscle cells connect together to form the long fibers found in muscle tissue. Structure of a Muscle Cell. As seen in the image below, a muscle cell is a compact bundle of many myofibrils.
Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell. Muscles function to produce force and motion.They are primarily responsible for maintaining and changing posture, locomotion, as well as movement of internal organs, such as the ...
The cell membrane of a muscle cell is called the sarcolemma, and this membrane, like that of neurons, maintains a membrane potential. So, impulses travel along muscle cell membranes just as they do along nerve cell membranes. However, the 'function' of impulses in muscle cells is to bring about contraction.
Structure of Skeletal Muscle. A whole skeletal muscle is considered an organ of the muscular system. Each organ or muscle consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue. Skeletal muscles vary considerably in size, shape, and arrangement of fibers.
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.
Structure of a Cell: The human body is comprised of 4 cell types (epithelial cells, muscle cells, nerve cells and connective tissue cells). Each cell type has components that are found in all cells, and unique modifications to components that give the cell type its unique attributes.
A myocyte (also known as a muscle cell) is the type of cell found in muscle tissue. Myocytes are long, tubular cells that develop from myoblasts to form muscles in a process known as myogenesis. There are various specialized forms of myocytes with distinct properties: cardiac, skeletal, and smooth muscle cells.
