The 21/20 Crew - The Nervous System Rap: No Brain, No Gain

CHECK OUT MY NURSING CHANNEL HERE: http://bit.ly/2kRBdTk The epic conclusion to the Biology 12 rap videos by Sep and JP. This video features Kian, Nathan, and some singing. Lyrics by JP. We do not own the music. If you've got wisdom, better start listening To this rap about the nervous system There are two subdivisions -- the central and peripheral Without either of them, you'd be a vegetable So if you want to think or eat or drink You need something to keep your body in sync The nervous system is what it's all about Because I don't know about you, but I hate Brussels sprouts! The Central Nervous System or CNS Allows all your bodily systems to coalesce It contains the brain and hordes the spinal cord It receives sensory info and initiates motor control The Peripheral Nervous System or PNS Conducts electrical signals when you feel a stress The voluntary branch is called the somatic The involuntary branch is called the autonomic! The nervous system connects head to toe Sending stimuli throughout it like ebb and flow Show some love -- without it you'd be dead, you know So listen up now cause I said let's go! If your knowledge of bio is foggy and blind Let Sep and JP unite your body and mind We'll give you a hand when you haven't a clue Because we're the twenty-one out of twenty crew! Don't be a moron, know your neuron I'm here to talk about it -- my name's Kian Neurons have three parts that I will recite The axon, cell body, and dendrite Dendrites collect signals, axons send 'em away Cell bodies make sure that everything is okay Together, Schwann cells make the myelin sheath We call it white matter, like the white of my teeth! It's essential to have good credentials Be sure to understand your action potentials Like how the impulse jumps between positions We call that saltatory impulse transmission During resting potential, the interior's negative Depolarization makes it relatively positive Re-polarization resets the axon The impulse moonwalks away like Michael Jackson! The nervous system connects head to toe Sending stimuli throughout it like ebb and flow Show some love -- without it you'd be dead, you know So listen up now cause I said let's go! If your knowledge of bio is foggy and blind Let Sep and JP unite your body and mind We'll give you a hand when you haven't a clue Because we're the twenty-one out of twenty crew! Aight it's Nate Doc's turn, it's time to learn About synapse transmission -- your main concern The doc's in da house and he'll explain in depth How the impulse jumps across the synaptic cleft When the action potential comes down the axon Its presence triggers a metaphorical klaxon Ion channels open, and in comes Ca Causing synaptic vesicles to be brought to the membrane! These vesicles exocytose neurotransmitters And since I know you were all wondering, here's my twitter: twitter.com/#!/CadetNate The inhibitory one is called acetylcholine The excitatory one is called norepinephrine They attach to receptor sites on the other side Channels open wide and in glides a sodium tide The impulse isn't stuck thanks to the Na influx Oop! Appointment over, schmuck. Two hundred bucks -- pay up! The nervous system connects head to toe Sending stimuli throughout it like ebb and flow Show some love -- without it you'd be dead, you know So listen up now cause I said let's go! If your knowledge of bio is foggy and blind Let Sep and JP unite your body and mind We'll give you a hand when you haven't a clue Because we're the twenty-one out of twenty crew! On to the brain, you won't feel pain This is the easiest section if you know what I'm sayin' The cerebrum senses, makes thoughts, memories, feelings of love When asked what it does, it's probably all of the above Which part of the brain maintains balance and motor skills? Well um That would be the co-ordination center, or cerebellum Last but not least -- it ain't for nada Your medulla oblongata will make you smata! Medulla oblongata, the best part of the brain Medulla oblongata, by far the most fun to say It controls reflexes to prevent your decay Regulates your heartbeat Helps you breathe and sneeze Medulla oblongata! Hold your horses -- we've got lot's to discuss Like the integrating center or hypothalamus It uses negative feedback to maintain homeostasis Creating an oasis on a regular basis The pituitary gland -- ain't it grand It understands the hypothalamus's commands It produces and releases various hormones Hope this helped, because after this you're on your own! The nervous system connects head to toe Sending stimuli throughout it like ebb and flow Show some love -- without it you'd be dead, you know So listen up now cause I said let's go! If your knowledge of bio is foggy and blind Let Sep and JP unite your body and mind We'll give you a hand when you haven't a clue Because we're the twenty-one out of twenty crew!
