Unipennate muscle

From Wikipedia, the free encyclopedia

Unipennate muscle

Different skeletal muscle types: A: fusiform. B: unipennate. C: bipennate. (P.C.S., physiological cross-section)
Latin	Musculus semipennatus, musculus unipennatus
Gray's	subject #102 361

In some muscles (e. g. the peronei) the fibers are, like the plumes of a quill pen, to one side of a tendon, which runs the entire length of the muscle; such muscles are termed unipennate.
