Muscle Spindle and Comparison of Fish Muscle Spindle with Other Vertebrates

33684

The aim of this study is to bring together the literature knowledge on muscule spindels that has been made up to until now and compare fish muscule spindels with other vertebrates. Muscle spindles are stretch receptor of skeletal muscles which detect the rate and degree of muscle length. According to the available literature, this review is considered as a one in making a comparison of fish muscle spindle and other vertebrates. Fish muscle spindle possesses single intrafusal muscle fiber similar to snake and lizard muscle spindle and have a double capsule similar in all vertebrates have studied. No significant differences in the length and diameter of intrafusal muscle fibers by comparison of muscle size. In fish and other vertebrates muscle spindles are supplied with one sensory ending (exception in mammalian may, in addition, be supplied with one or more secondary sensory endings) and receive its motor innervation from branches of axons that also innervate extrafusal muscle fibers. No investigation has been done about motor innervation of fish muscle spindle.
