WitrynaExample. A simple example of muscle spindle activity is the knee jerk reflex (Patellar reflex), sudden kicking movement of the lower leg in response to a sharp tap on the patellar tendon, which lies just below the kneecap.Tapping on the tendon of the knee extensor muscle group below the patella stretches the muscle spindle fibers. This … WitrynaAt prometaphase (late prophase) the chromosomes condense inside the nuclear envelope and asters of fibers appear on the outside of the chromosomes. When the nuclear envelope has disappeared, a spindle forms in prometaphase. The spindle fibers comprise bundles of microtubules radiating from the opposite ends and …

What are Spindle Fibers? Their Role in Cell Division

Muscle spindle - Wikipedia

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 … connect trezor to uniswapWitrynaDuring mitosis, the spindle fibers are called the mitotic spindle. ….
