Of the three types of muscle, the two that are involuntary are cardiac muscle and smooth muscle.

Two factors affecting muscle fiber thickness are genetics and the type of training or exercise performed. Genetics play a role in determining the natural thickness of muscle fibers, while specific training regimens that target muscle hypertrophy can increase muscle fiber thickness over time.
A single muscle cell is called a muscle fiber.
The two main muscle fiber types are slow-twitch (Type I) fibers and fast-twitch (Type II) fibers. Slow-twitch fibers are better for endurance activities as they are more resistant to fatigue, while fast-twitch fibers are better suited for explosive, powerful movements.

Incorporating exercises that target all three muscle fiber types into a workout routine can help improve overall muscle strength, endurance, and performance. By targeting different muscle fibers, you can enhance muscle growth, increase muscle tone, and improve overall athletic performance. This variety in exercises can also prevent muscle imbalances and reduce the risk of injury.
The sarcoplasmic reticulum in muscle fiber corresponds to the endoplasmic reticulum in other cell types. The sarcoplasmic reticulum is a specialized type of endoplasmic reticulum found in muscle cells, and it plays a key role in calcium storage and release during muscle contraction.
Each muscle fiber is also called a myofiber.
