Definition:
(a.) Alt. of Pinnated
Example Sentences:

(2) The lengths and pinnation angles of muscle fibers in the medial gastrocnemius (MG) muscle have recently been measured in freely moving cats [Hoffer et al., Progr.
(3) This region appeared to be composed of extrafusal fibers that were shorter and of more oblique pinnation than those in other regions.
(4) The loss of fiber force due to (pinnate, not equivalent) angulation is compensated for by the reduced shortening of fibers in multipinnate arrays.
