Question

Classify the following characteristics by dragging them from the top into the box corresponding to the skeletal muscle fiber type they best describe Have many mitochondría and fast contraction velocity Produce ATP mostly by oxidative phosphorylation and have low Also called type I fibers and have Large fiber diameter and largest diameter motor neuron high myoglobin content glycogen content Have few mitochondria and fast and slow phosphorylation and have intermediate glycogen content Have many capillaries and low glycolytic enzyme activity This type of motor unit is only Motor units are intermediate in the Have many capillaries and recruited for the highest intensity of whole-muscle contractions number of muscle fibers per motorintermediate glycolytic enzyme Small fiber diameter and low myosin ATPase activity neuron activity Produce ATP mostly by glycolysis Also called type Ilb fibers and have and have high glycogen content Also called type lla fibers and have Mainly this type of motor unt is recruited for low-force whole low myoglobin content high myoglobin content Fast-Oxidative-Glycolytic Fibers Slow-Oxidative Fibers Fast-Glycolytic Fibers Reset

Explanation / Answer

Answer

Slow Oxidative Fibers Fast Oxidative Glycolytic fiber Fast Glycolytic fibers Also called Type I fibers and have high myoglobine content have many mitochondria and fast contraction velocity have few mitochondria and fast contraction velocity have many capillaries and low glycolytic enzyme activity Also called Type IIa fibers and have high myoglobine content this type of motor unit is recruited for the highest intensity of whole body cotractions. this type of motor unit is recruited for the low force whole body cotractions ave many capillaries and intermediate glycolytic enzyme activity Also called Type IIb fibers and have low myoglobine content small fiber diameter and myosin ATPase activity motor units are intermediate in the number of muscle fiber per unit neuron. large fiber diameter and largest diameter motor neuron produces ATP mostly by Oxidative phosphorilation and have low glycogen content produces ATP mostly by Oxidative phosphorilationand have intermediate glycogen content produces ATP mostly by glycolysis and have high glycogen content Have many mitochondria and have low muscle contraction velocity
