1

how does the intervertebral disc attach to the vertebral body

sharpey's fibers from the outer lamella of the annulus fibrosis are firmly embedded into the epiphyseal rims of the adjacent vertebral bodies

2

popular theory of intra-abdominal cavity pressure and intervertebral disc response to weight bearing

increasing the intra-abdominal cavity pressure will diminish the amount of resistance the intervertebral disc needs to generate by up to 50%

3

based on histology, what is the classification of the intervertebral disc

cartilaginous (amphiarthrosis) symphysis

4

division of the embryonic somite

sclerotome, myotome, dermatome

5

structure that is formed following migration of sclerotomes to surround the notochord

perichordal blastema

6

formed within the perichordal blastema between the sclerotomites

intrasclerotomal fissure or fissure of von Ebner

7

what does intrasclerotomal fissure or fissure of von Ebner become

perichordal disc

8

what will the dense sclerotomite become

upper part of the vertebral segment forming below

9

structure that forms following migration and subsequent mixing of the sclerotomites

vertebral blastema

10

part of the intervertebral disc that will form the notochord

nucleus pulposus

11

part of the intervertebral disc that the perichordal disc will form

annulus fibrosus

12

the earliest indicator of the position of the adult intervertebral disc

intrasclerotomal fissure or fissure of von Ebner
