Nuclear chain fiber
WebMuscle spindles are composed of intrafusal fibers, modified skeletal muscle fibers of two types, nuclear bag and nuclear chain fibers. Changes in skeletal muscle length are detected by concurrent changes in intrafusal fibers that relay these sensations to the CNS by axons of sensory, pseudounipolar neurons. 800x WebNuclear chain fibers contained MyHCIIa, embryonic, and fetal isoforms with regional variations. We also compared the present data with our previous results obtained from muscle spindles in human biceps brachii and the first lumbrical muscles.

WebType II neuron fibers branch out and attach to the ends of the central region of the nuclear chain fibers and relay information about how far the muscle is being stretched. In addition, gamma motor neurons innervate both ends of the intrafusal muscle which contain actin and myosin, and when stimulated, the gamma motor neurons cause these end regions to … Webnucleo-: , nucl- Nucleus, nuclear.

WebDynamic Nuclear Bag fibers. These fibers are anatomically similar to the static nuclear bag fibers, but they signal primarily information about the rate of change (velocity) of muscle length. A typical muscle spindle is composed of 1 dynamic nuclear bag fiber, 1 static nuclear bag fiber, and ~5 nuclear chain fibers.
