What Are Connective Tissue Wrappings?

This connective tissue covering is known as the endomysium

(endon - greek for within). The collagen fibres of these connective tissue wrappings merge with the tendons, aponeuroses, or periosteum - the dense connective tissue structures that link the muscle to bone, on which the muscle pulls.

What are the connective tissue wrappings for each bundle?

Each bundle of muscle fiber is called a fasciculus and is surrounded by a layer of connective tissue called the perimysium. Within the fasciculus, each individual muscle cell, called a muscle fiber, is surrounded by connective tissue called the endomysium.

Why are connective tissue wrappings important?

The connective tissue wrappings (a) bundle the muscle fibers together, increasing coordination of their activity; (b) add strength to the muscle; and (c) provide a route for entry and exit of blood vessels and nerves to the muscle fibers.
