Webarranged on a same volume of muscle. For that reason, penniform muscles are able to produce more force than fusiform muscles of similar volume, on the other hand they produce less displacement (Hamill, 1999; Watkins, 2001). The majority of the muscles of the human body need to exert more force than a simple fusiform architecture is able to provide. WebA Doubly Penniform Muscle. the Penniform the fibres are short and arranged upon a long tendinous line, like the plumes upon the quill of a feather. The circular form, called Sphincter, is found in parts of the b >dy where the fibres are circular, surrounding some orifice which they partially or entirely close up by their contraction. law online form https://wakehamequipment.com
