A&P Muscular System (1)

The organization of muscle at the tissue level is described as:

• Muscle fibers are grouped into fascicles, which are surrounded by perimysium.

• Muscle fibers are randomly distributed without any specific organization.

• Muscle fibers are organized into layers with no connective tissue.

• Muscle fibers are isolated and not connected to each other.
