Question

multiple choice question

muscle fibers are bundled together into fascicles by which connective tissue layer?

endomysium
epimysium
perimysium

Explanation:

Identify the target structure

The question asks for the connective tissue layer that bundles muscle fibers together into groups called fascicles.

Analyze the options

• Endomysium: This is a thin sleeve of loose connective tissue that surrounds each individual muscle fiber.
• Epimysium: This is a fibrous sheath that surrounds the entire skeletal muscle as a whole.
• Perimysium: This is a thicker connective tissue sheath that groups muscle fibers into bundles called fascicles.

Connect to muscle characteristics

Using the Muscle Characteristics knowledge point, we look at how skeletal muscle is organized structurally. The layer responsible for wrapping individual fibers into bundles (fascicles) is the perimysium.

Answer:

• Endomysium
• Epimysium
• Perimysium (Correct answer)
