Skeletal Muscle
• The cells are called muscle fibers because of their elongated shapes.
• The muscle fiber cells has many nuclei because each muscle fiber cells
arises (during embryonic development) from the fusion of small cells called
Myoblasts
• Skeletal muscle fibers cannot divide and have limited powers of
regeneration
• The typical length of a mature skeletal muscle fiber varies from 10-30cm
• Skeletal muscle is an organ composed of multinucleated and striated cells.
• Intramuscular injections are commonly injected in skeletal muscles:
• Examples:
• Deltoid muscle in shoulder region
• Gluteus medius muscle in buttock region
• Vastus lateralis in the thigh region
