Question

Bundles of striated muscle fibres fasciculi are surrounded by a sheath called as

• A. Epimysium
• B. Perimysium
• C. Exomysium
• D. Endomycium

Answer 1

The correct option is B Perimysium

Perimysium is the fibrous sheath that covers each bundle (fascicle) of single muscle fibres. It consists collagen, but also intramuscular fat (marbling), blood vessels and nerves that maintain blood flow and innervate the fascicles. Each fascicle receives branches of these blood vessels and nerves.

Endomysium is connective tissue that wraps each individual muscle fibre.

Epimysium or exomysium is connective tissue that wraps the whole muscle.

So, the correct answer is option B.
