Lumbar Vertebrae (L1-L5) Anatomy

so we look at the lumbar again if you

remember what we said we breakfast at

7:00 lunch at 12 and dinner at 5 so we

have seventh cervical vertebrae 12

thoracic vertebrae and we're gonna have

five lumbar vertebrae lumbar is really

really weight-bearing I look at the

centromere look at that body it's really

really thick body right there okay it's

a really really thick body these are

gonna be your transverse processes again

these right here your superior

articulating process with facets right

they're superior to any process of

facets and again here's our spinous

process right there spinous process

again forty before Aemon and then if you

get here's actually a better way I would

actually rather you look at the lamina

and the pedicle on this one if you look

here I were to take and wrap around that

part right there again it's that space

between the spinous process and the

trans actually go there transverse

process this right here is actually

called the lamina now if I flip it

around here sorry guys and I go in

between the body and the transverse

process this chunk right there is

actually called the pedicle okay so I

just want to show you guys that it's

better seen on that and again I'm gonna

flip it over here so you can see a

couple of parts again that's the body

and right here is your inferior

articulating process with facets and it

get me in fair ticularly process or

facets and then again vertebral canal

where the spinal cord runs through all

right what I want to do real quick

actually before I move on is if you

notice here I have a two lumbar vertebra

and if you notice right here what I

wanted to show you is these little

things here these are actually called

the intervertebral discs right here and

this is actually the one act as the

cushion basically it's kind of like a

shock absorber here and they have this

annulus fibrous tissue wrapping around

it's kind of interweaved really really

thick connective tissue and then inside

of it you have a little jail thing

called a nucleolus papoul psious and

these basically again are basically

designed to be a shock absorber and that

is a cushion so whenever the actual

vertebrae is being compressed it helps

to be able to allow for that compression

to occur and one other thing I wanted to

show you right here is if you look here

this guy right there this is actually

going to be called the inter vertebral


Tibor foramen is where your spinal

nerves run through make sure you don't

get that confused with the vertebral

foramen right there so there's the

vertebral foramen and this is the inter

vertebral foramina
