Flashcards in Intervertebral Disc: Cartilaginous End Plate and Transition Zone Deck (20):
1

what is the cartilage end plate derived from

epiphyseal plate

2

what is the thinnest part of the cartilage end plate

central part, over the nucleus pulposus

3

part of the vertebral body that the cartilage end plate WILL cover

cancellous bone at the top or bottom of the vertebral body

4

part of the vertebral body upper and lower surfaces the cartilage end plate WILL NOT cover

epiphyseal rim

5

attachment site for collagen fibers of the inner lamellae of the annulus fibrosus

cartilaginous end plate

6

cell type is associated with the cartilage end plate

chondrocytes

7

earliest indicator of intervertebral disc pathology or degeneration

changes in the histology of the cartilage end plate

8

what is the area of maximum metabolic activity in the intervertebral disc

transition zone

9

part of the intervertebral disc that is innervated

outer lamellae of the annulus fibrosus

10

part of the cervical intervertebral disc that is highly innervated

middle third of the annulus fibrosus

11

types of receptor endings in the intervertebral disc

nociceptors and proprioceptors

12

the relationship between size of the intervertebral disc and receptor endings

larger the disc, the greater the variety of receptor endings

13

recurrent meningeal/sinu-vertebral/sinus vertebral nerve originate from which source

gray ramus communicans

14

part of the intervertebral disc innervated by the recurrent meningeal/sinu-vertebral/sinus vertebral nerve

outer lamellae of the annulus fibrosis at the posterior part of the intervertebral disc

15

forms the ANTERIOR neural plexus of the vertebral column

fibers from the ventral primary ramus

16

forms the POSTERIOR neural plexus of the vertebral column

fibers from the ventral primary ramus,
fibers from the white ramus communicans,
fibers from the paradisal ramus communicans,
fibers from the gray ramus communicans

17

name given to the white ramus communicants which becomes embedded within the annulus fibrosis of the intervertebral disc

paradiscal ramus communicans

18

what part of the intervertebral disc is innervated by fibers from the paradiscal ramus communicans

outer lamellae of the annulus fibrosis at the lateral part of the intervertebral disc

19

principle type of collagen fibers within the cartilage end plate

type II collagen fiber

20

direction of collagen fibers within the cartilage end plate

collagen fibers are aligned anterior to posterior
