What layers of connective tissue sheaths form a tendon?

Endotenon is contiguous with epitenon, the fine layer of connective tissue that sheaths the tendon unit. Lying outside the epitenon and contiguous with it is a loose elastic connective tissue layer known as paratenon, which allows the tendon to move against neighbouring tissues.

What layers of the connective tissue sheaths from a tendon?

Each bundle of muscle fiber is called a fasciculus and is surrounded by a layer of connective tissue called the perimysium.

What is a Paratenon?
