Unipennate is a term used in biology to describe the structure of a particular type of muscle fibre. This term refers to muscles that have a single row of fibres running along one side of their central tendon. Some synonyms for this term include "monopensate," which is another way to describe the same type of muscle fibre. Other synonyms include "simple pennate," "unicatal Pennate," and "anatrope Pennate." Each of these terms describes the same type of muscle structure, but they use different language to convey the same idea. Regardless of which term is used, these muscles are essential for the movement and support of the human body.
