Question

Describe the difference between a tendon and an aponeurosis.

Expert Solution
Step 1

Our bones, muscles and joints serve jointly in a cooperative way to move our body and allow it durability and stability.

Step 2

A tendon is an outgrowth of connective tissue beyond the muscle's edges that binds to the bone. A band of hard, fibrous, inelastic tissue that attaches a muscle to a bone, an example of a tendon is the Achilles tendon. Tendons permitting us to move, and ligaments support us to carry things in place. The stability of tendons is significant as these rigid configurations are needed to avoid the forces of massive loads.

An aponeurosis is a broad fibrous sheet that attaches muscles to surrounding muscles. It is (anatomy) a flattened fibrous membrane. Aponeuroses are expansions of external tendons covering pennate muscles, function as insertion sites for muscle bundles, and modulating fascicle rotation and gearing during muscle contractions. The aponeurosis assembled dense fibrous connective tissue, including fibroblasts and collagenous fibres, in systematic formations.
