Classification
Nouns denoting body parts.
Examples
- A striated muscle fiber is an elongated contractile cell in striated muscle tissue that plays a crucial role in movement and locomotion.
- The striated muscle fiber contains repeating units of sarcomeres that give the cell its striated appearance under a microscope.
- Striated muscle fibers are multinucleated cells, meaning they have multiple nuclei, which allow them to produce more proteins and increase their contractile force.
- Each striated muscle fiber is surrounded by a network of tiny tubules called the sarcoplasmic reticulum that helps regulate muscle contraction.
- Striated muscle fibers are found in skeletal muscles and are responsible for voluntary movements, such as walking, running, and lifting.
