This is brilliant Sam! Your knowledge, intent and ability to explain the fundamentals are exceptional. Thanks!

Thank you dear Sam , you are awesome, God bless you حفظكم الله🙏

Wow myotatctic reflex, reflex arcs, brachial plexus, cervical vertebrae, upper limb nerves! hard topics but you make easy, thanks! Anyway I had to watch tree times to get the full picture . But Now I understand what happens when my master make us repeatedly tap all our tendons. Thanks doc!!

Love your work as always, Sam! I came across this video because I am trying to solve a query regarding the brachioradialis reflex. I had assumed it's alternative name was the supinator reflex simply because the test is usually performed on a flexed elbow and pronated forearm, therefore brachioradialis would pull the forearm from pronated to a slightly ore supinated (but still pronated relative to the anatomical position). One of my colleagues believed differently, that it was actually because the brachioradialis reflex also activates radial nerve efferents to supinator. In my brief literature search I could find sources that state the reflex can involve flexion of the hand, as well as supination OR pronation of the forearm, and elbow flexion. Do you know much about this reflex arc? Do you know what causes the supination/pronation/finger flexion?

Hello, Mr. Webster; wonderful video as always! Will it be safe to say that the inhibitory neuron, which is targeting the antagonistic muscle, is causing the muscle to contract eccentrically in order to let the concentric contraction of the flexor muscle? Or, is the inhibitory neuron just preventing the antagonistic muscle to contract at all? Thank you :)

[@SamWebster]

The inhibitory neuron inhibits contraction of the antagonistic muscle.
