Skeletal muscles are grouped right into fascicles, which space bunches of muscle fibers surrounded by a perimysium.

You are watching: The connective tissue that surrounds a muscle

Key Points

bones muscle is surrounding by a thick connective paper the fascia underneath this is one more layer the connective tissue dubbed the epimysium, i m sorry extends inwards as the perimysium right into the muscle, dividing fibers right into bundles fascicles. Each fascicle is surrounded by an additional layer of connective organization the endomysium. This framework separates and protects the muscle and additionally acts to spread pressure throughout the muscle, staying clear of damage.

Key Terms

perimysium: The continuation of the epimysium into the muscle, splitting fibers into fascicles. epimysium: A sheet of connective tissue lying below the fascia, additionally surrounding a muscle. fascia: A paper of special connective tissue which surrounding a muscle. endomysium: A paper of connective organization which wraps each fascicle. fascicle: A team of muscle that fibers surrounding by the perimysium.

Muscle Fascia


Muscle Structure: skeletal muscle is surrounded by a thick outer layer that connective organization the fascia. Within this is a class the epimysium i m sorry splits inwards right into the muscle as the perimysium separating muscle yarn into groups fascicle. Every fascicle is surrounded by an additional layer the connective organization the endomysium.

Skeletal muscle organization is composed of countless muscle yarn which room separated from adjacent muscles and other organization by a layer of dense, elastic connective tissue the fascia. This fascia have the right to project past the finish of the muscle and attach come bones, various other muscles, and other tissues. Crucial muscle groups and the connected vascular and nervous solution can likewise be separated from various other tissue, such together in the top arm. This groupings are referred to as fascial compartments.

This fascia is interlinked through a major of fascia uncovered throughout the body, consisting of the superficial fascia i m sorry is the lowermost great of the skin and also the visceral fascia i m sorry surrounds inner organs. The fascia bordering a muscle or muscle team does no contain numerous blood vessels, but is rich with sensory receptors.

Muscle fascia is predominately composed of cross-linked collagen and elastin yarn oriented parallel to the direction that muscle force, make them may be to resist high-tension pressures while continuing to be somewhat elastic.


Beneath the fascia in bones muscle is another layer of connective organization the epimysium i beg your pardon is closely connected with the fascia. That extends inwards and also becomes the perimysium, then right into the muscle separating muscle yarn into small bundles fascicles. Fascicles have the right to be i ordered it in a selection of anatomical positions within a muscle, creating different movements.

Each individual fiber in ~ a fascicle is surrounded by a thin connective layer the endomysium, which helps preserve close association between the muscle fiber and also associated vascular and nervous systems.

The company of connective tissue throughout and also around a muscle provides strength and also flexibility while distributing the force evenly. It also maintains the close association of the vascular and nervous device with the muscle, i beg your pardon is compelled to deliver necessary metabolites and also nerve impulses.

Cardiac and Smooth Muscle Tissue

Whilst both cardiac and also smooth muscles are additionally wrapped in connective tissue, they room not differentiated in the same way as bones muscles.
