Muscle spindles are stretch receptors within the body of a skeletal muscle that primarily detect changes in the length of the muscle. They convey length information to the central nervous system via afferent nerve fibers. This information can be processed by the brain as proprioception. The responses of muscle spindles to changes in length also play an important role in regulating … WitrynaAt prometaphase (late prophase) the chromosomes condense inside the nuclear envelope and asters of fibers appear on the outside of the chromosomes.
