Ma'am you're notes are awesome

[@PhysiologyOpen]

Thanks a lot 😊 Do tell your friends and juniors

[@sansritigupta8005]

And mam please do upload the experimental physiology before the professional exams before january.

[@PhysiologyOpen]

I am trying

[@rajashreebhaduri5666]

Very nicely explained maam

[@PhysiologyOpen]

Thanks Rajashree

[@Breathingpollution]

Mam did it follow all or none law??pls explain

[@PhysiologyOpen]

Yes it does. . Here motor unit follows all or none law. Recruitment of motor units means - each motor unit is following all or none law

[@Vasudeva061]

It didn't violate the All or none Law...As All or none law for skeletal muscle is applicable for single muscle fibre only... As this experiment recruits many motor units i e many muscle fibres.. So it didn't violote the law

[@PhysiologyOpen]

Is it applicable for single muscle fibers?

[@Vasudeva061]

@@PhysiologyOpen Yeah ma'am I thought like that.... But now I am confused... Can you please elaborate ma'am?,🥲🙂

[@PhysiologyOpen]

Actually you are right except that all or none law is followed at the level of motor unit. Yes each muscle fiver does follow, but in body, single motor neuron stimulation leads to motor unit stimulation

[@sansritigupta8005]

Mam can you please complete all the topics of reproductive physiology as the playlist is incomplete.

[@PhysiologyOpen]

Sanskriti it is difficult for me to do that before exams . Kindly refer to my notes on play.google.com/store/apps/details?id=co.rogers.ezlep&pcampaignid=web_share

[@sudhankarthi4164]

Yes mam , it violates all or none law , because some set of motor units are only exciting

[@PhysiologyOpen]

Actually it doesn’t. In skeletal muscle all or none applies only to motor unit. Here strength of contraction is increasing due to motor unit recruitment
