During restricted periods of development (embryonic day (E) 14.5-E15.5 in mice 1), peripheral innervation of a subset of type I myotubes by group Ia sensory (but not motor 9) axons provides ...

Spindles differ from other sensory receptors as they also receive nerve fibers from the central nervous system itself, which acts to control spindle output. There are more nerve fibers travelling to ...

SPASTICITY REFERS TO AN ABNORMAL, velocity-dependent (i.e., how fast the joint is moved through its range) increase in muscle tone resulting from interruption of the neural circuitry regulating the ...

Scattered throughout skeletal muscle, the muscle spindles are composed of connective tissue capsules containing bundles of specialized muscle fibers called intrafusal fibers. Wrapped around the middle ...
