Verified Answer
Which of the following correctly identifies muscle components in order...
The organization of muscle components from largest to smallest is as follows:
- Fasciculus: A fasciculus is a bundle of muscle fibers surrounded by connective tissue.
- Muscle fiber: Also known as a muscle cell, a muscle fiber is a single elongated cell that makes up the muscle tissue.
- Myofibril: A myofibril is a cylindrical structure within the muscle fiber composed of contractile proteins called actin and myosin. It is responsible for muscle contraction.
Therefore, the correct order is fasciculus, muscle fiber, and myofibril.
Most Upvoted Answer
Which of the following correctly identifies muscle components in order...
Components of Muscles:
Muscles are composed of several components that work together to facilitate movement. These components are organized in a hierarchical manner, with each level contributing to the overall function of the muscle. The correct order of muscle components from largest to smallest is as follows:
Fasciculus:
- Fasciculus is a bundle of muscle fibers surrounded by perimysium.
- It is made up of multiple muscle fibers that work together to generate force.
- Fasciculus is the largest component in this hierarchy.
Muscle Fiber:
- Muscle fiber, also known as a muscle cell, is the basic structural unit of a muscle.
- It is a long, cylindrical cell that contains myofibrils responsible for muscle contraction.
- Multiple muscle fibers make up a fasciculus.
Myofibril:
- Myofibrils are thread-like structures found within muscle fibers.
- They are composed of sarcomeres, which are the functional units of muscle contraction.
- Myofibrils contain the contractile proteins actin and myosin that slide past each other to generate force.
Therefore, the correct order of muscle components from largest to smallest is: Fasciculus, Muscle Fiber, Myofibril. This hierarchical organization allows for efficient transmission of force generated by muscle contractions, enabling movement and locomotion.
