USCOT441 myotatic reflex music video with vocals USC OT 441 OT441 stretch / deep tendon

here is the final vid for this myotatic reflex song. this was my extra credit assignment for OT441 neuroscience at USC. the singing is… well… it still makes me laugh. i hope you enjoy this and learn this reflex at the same time 🙂 Fight on trojans! Myotatic reflex- to R. Kelly’s “Remix to Ignition” Lyrics by Pierre Clay I’m gonna tap your knee a myotatic reflex we’ll see It will start with a stretch and ends when it contracts It happens in the PNS as well as in the CNS They are all involuntary, as we will see in the knee So gimme that tap tap and I’ll show you my reflex Makin’ my muscle stretch out, and make my knee kick about, It’s ’cause it’s about reflexive routes When muscle fibers get lengthened, spindle fibers get lengthened Afferent 1As not 2s — sense quick muscle length as good news The spinal cord gets this news then it splits up in twos Alpha motor efferent’s cause agonists to contract TAP- KICK TAP-KICK TAP-KICK *We be kickin’ our knee when they tappin’ our knee it’s all involuntary Now there’s some inhibition- it puts antag.s in submission We have inhib. INs they connect to alpha MNs Both these paths will inhibit antagonists will prohibit Reflexive contraction in myotatic reflex What will happen when our muscles will shorten And muscle spindles get slack, what receptor will act? The GTO turns on and the 1Bs get squished We bring ’em both together then the gamma will turn on So after the reflex it’s the upper neuron And after the upper it’s muscle spindle …
