Correlative Study of the Physiologic and Morphologic Characteristics of the Temporal and Masseter Muscles of the Cat

Abstract
The electrophysiologic and morphologic features of cat temporal and masseter muscles were investigated. The temporal muscle possessed a majority of type A fibers; type B and C were dominant in the masseter muscle. The temporal muscle demonstrated slower contraction speed, wider twitch duration, and earlier tetanus fusion than the masseter muscle.
