What Is The Advantage Of A Small Motor Unit? In most skeletal muscles, the small motor units innervate small “red” muscle fibers that contract slowly and generate relatively small forces; but, because of their rich myoglobin content, plentiful mitochondria, and rich capillary beds, such small red fibers are resistant to fatigue. What is the difference
What Is The Difference Between A Large And A Small Motor Unit? Small α motor neurons innervate relatively few muscle fibers and form motor units that generate small forces, whereas large motor neurons innervate larger, more powerful motor units. What does the size of a motor unit determine? Motor unit recruitment is a measure of
What Is The Smallest Motor Unit In The Human Body? SIZE. The smallest motor units are in muscles that must produce very fine gradations of force: lumbricals: 100 fibers/unit. … DISTRIBUTION WITHIN MUSCLE. The fibers that make up a motor unit are not adjacent to one another, but they inhabit the same general region of
