| Abstract: | Summary Histochemical profiles of intrafusal fibers have been examined in muscle spindles of extraocular muscles of sheep and pig. Results show that in the sheep the intrafusal content presents, in addition to chain fibers, at least one bag1 and one bag2 fiber, whereas in the pig almost all the spindles are bag1-fiber spindles.Acknowledgment. This study was supported by grants from C.N.R. and M.P.I. |
