I don't even know how to thank you..i swear to god u explain better than my collage professor, thank u so so much! I understood it very well and i can't be more thankfull😭🌸 god bless u for helping lost students like me hehe
Can u explain the reflex action when there is sudden decrese in length of muscle. Stretch means to lengthen not to decrease. According to ur lecture if 1a fibres stimulate alpha motor neuron of same muscle fibers then they cause muscle contraction. How come they cause relaxation as u mentioned it just by a sentence and escaped from explaining (6:19)
Hello pls i can't get a point: i can't understand how the contraction of peripheral part of intrafusal fiber lead to stretch of muscle spindle? Cuz i can't imagine it if the peripheral part gonna contract this will lead to central part contraction
