- Hil Today I" be walking youthrough thè neryous system, evenright now i'm using my'spinal cordto hold myself up and am using,mybrain to remember what l'm goingto say. I hope you learn somethingalong the way.
- INTRO
- REFLEXES
- Here, you can see Mrs. Ameliabed tried but to EE up her from balance. her hospital Luckily.her son Landon's quick reflexescaught her in time. The motor orefferent neurons allowed Landonto initiate his reflexes by carry-ing the signals away from thebrain.
- Renexes are bodily re-sponses that don't needthe brain to create ac-tion. How cool is that?1Notably, intermneuronsparticipate in a renex so.because interneuronsare in the spinal cord,there is more than onesynapse occurrence.
- An ambulance somewhat represents aneuron because it's job is to transportpatients to the hospital where they canget treatment. just like what would'vehappened if Landon hadn't intervened.
- Next, we'll talk about neurons.Neurons are responsible for car-rying messages through the ner-vous system, which controls thefunctions of the human body!
- NEURONS
- Oh no! Looks like Landonwasn't careful and burnedhis arm a bit, but luckily hefinched and moved away intime thanks to his SensoryNeurons.
- The skin color change on theburn area refers to reaction andstimuli, stimuli is somethingthat evokes a response. So, theredness is the response to thestimuliof being burned,This isalso called an afferent neuron.
- SENSORY NEURONSRESPONSEISTIMULI
- Let's talk about nerve impulses! Nerve impulses areresponsible for transmittingsignals through the neryoussystem across a nerve fiberl
- Mrs. Amelia is feeling a bitbetter, she's trying to give acallto her sister, Hannah totell her what a hero Landonwas. This is a real life exampleof nerve impluses, becausephone signals are working asShe's calling.
- NERVE IMPULSES
- Afterwards,when discussing thepsychology of the events of the day.they started talking about thePeripheral Nervous Systempns)which is the other part that makesup the nervous system. It containsthe ganglia and spinal cord.
- It also connects the CentralNervous System to organs.limbs, and skin. It can alsoserve as a communicationrelay between the brain andevents.
- PERIPHERAL NERVOUSSYSTEM
