Select an appropriate antimicrobial to target a given microorganism. Smooth muscle tissue can be subdivided into two categories depending on whether the cells contract collectively and simultaneously (single-unit smooth muscle) or work independently (multi-unit smooth muscle). Its also possible to use Labster without an LMS. labster muscle tissues quizlet - Fluorescent Microscopy These are dense and rich in myoglobin and mitochondria. Gut Contracts. A muscles strength depends mainly on how many fibers are present. Instead of a calcium trigger which sets off a contraction reaction, smooth muscle has more of a throttle, like in a car.
