Spine Basics (How to memorize segments, number of vertebrae, curves and actions)

How many you guys know the spine pretty good, kind of. Alright so let's talk about how to memorize some of the details of the spine. You got this big curvy thing with a lot of bones 7, 12, and 5. How many guys have ever heard 7, 12, and 5? How do you guys remember 7, 12, 5, breakfast, lunch, and dinner. If we still lived in the 1950s you guys would wake up and have breakfast at seven. We'd all get a lunch break at 12, and you'd come home to dinner at five right. Now you guys are students, and I work all the time all over the place, so when do we eat? Whenever we can shove food in our mouths. I think that's when we eat. But if we go back to 7, 12, and 5, so we have seven what type of vertebrate, cervical vertebrae. So those vertebrae in blue there, are seven cervical vertebrae. What's special about the cervical vertebrae, where do they exist? The neck, those are your neck vertebrae. Alright 12, 12 12 12 12 12 ,12 refers to which vertebrae? The thoracic vertebrae. So I have 12 thoracic vertebrae. What's special about my thoracic vertebrae? They attach to my 12 ribs, making up my thorax right, and lumbar is where your low back is, where I have how many vertebrae? Five. You want to know a fun fact, how nerdy I am, you guys ready for this? This 7, 12, 5 scheme same for all mammals, you guys are like that's fun fact. Now let me explain, let me explain. A giraffe still has seven cervical vertebrae, how ridiculous is that, they're just like this tall, that's no joke. Seven cervical vertebrae in a giraffe, and then you look at a shrew. You guys ever seen a shrew? The thing has no neck, somebody attached its head to its shoulders. There's still seven cervical vertebrae. Whales still have a 7, 12, 5 scheme. Their sacrum and coccyx are separated, but they still have the same 7, 12, 5. I was in I think it's the Chicago Airport, and there was a giant skeleton of a brontosaurus. Of course so what do i do, I stop but I start looking at it, people must think I'm freaking crazy at this point right, there like what the heck is he doing, and sure enough i'm sitting there counting, i'm going that son of a bugs got seven cervical vertebrae, and he had all the same landmarks too. Like it was crazy, like the same transverse process, spinous process, like I could still point to the lamina, and all of those fun little anatomical things about vertebrates they were still there. So 7, 12, 5 a little more interesting now? Or no, now you guys just think I'm that much more nerdy. Guys should know my friends call me Sheldon, that's totally true. Alright, so we got low back lumbar vertebrae. We also have curves to remember in your low back lumbar vertebrae, You have a lordotic curve. You guys with me, so make that little letter association. Low back is your lumbar spine, and you have a lordotic curve, that's the inward curve. Now the opposite of lordotic curve is a kyphotic curve. Where do we find a kyphotic curve? The thoracic spine has a kyphotic curve. So what type of curve does the cervical spine have? It's another lordotic curve. So you have lordotic, kyphotic, lordotic. If you remember it from the bottom up, low back, lumbar spine, lordotic curve, you're in good shape. Now let's see if we can do this without me, and going to the next slide. What are the joint actions of my spine? Flexion, extension of my sagittal plane motions. Lateral flexion is my frontal plane motion, and then what's my transverse plane motion at the spine? Rotation. You guys nailed it, nailed it.
