Nettet5. apr. 2016 · Found in specialist structures like the eye. Individual muscles are a mixture of 3 types of muscle fibers (type 1 and type 2a and b), but their proportions vary depending on the action of that muscle.Type It must be remembered that skeletal muscles, although a mixture, can only have one type of muscle fiber within a motor unit.

Initially, whole muscles were classified as being fast or slow based on speeds of shortening. 3 This division also corresponded to a morphological difference, with the fast muscles appearing white in some species, notably birds, and the slow muscles appearing red. The redness is the result of high amounts of myoglobin …
NettetOne alpha motor neuron along with all of the muscle fibers it innervates is a motor unit . The size of the motor unit correlates with the function of the muscle. In muscles involved with fine, coordinated control, the motor units are very small with 3-5 muscle fibers per …
NettetExplain. The latchbridge mechanism, found only in smooth muscle, permits smooth muscle cells to remain contracted after calcium has been removed, without further hydrolysis of ATP. This results in a prolonged duration of contraction with low energy requirements. Thus smooth muscle is relatively resistant to fatigue. rocking chair in heavenNettetQuestion: Match the descriptions with the correct types of motor units.
