intervertebral disc Cartilaginous end plate and transition zone Flashcards
What is the cartilage end plate derived from
the epiphyseal plate
what part of the vertebral body will the cartilage end plate cover
the central part, over the nucleus pulposus
what is the principal type of collagen fiber within the cartilage end plate
type 2 collagen fiber
what is the direction of collagen fibers within the cartilage end plate
collagen fibers are aligned anterior to posterior
what is the earliest indicator of intervertebral disc pathology or degeneration
changes in the histology of the cartilage end plate
what is the area of maximum metabolic activity in the intervertebral disc
the transition zone
What part of the intervertebral disc is innervated
the outer lamellae of the annulus fibrosus
what part of the cervical intervertebral disc is highly innervated
the middle third of the annulus fibrosus
What are the types of receptor endings in the intervertebral disc
nociceptors and proprioceptors
what is the relationship between size of the intervertebral disc and receptor endings
the larger the disc the greater the variety of receptor endings
the recurrent meningeal/sinu-vertebral/sinus vertebral nerve has typically been shown to originate from which source

what part of the intervertebral disc is innervated by the recurrent meningeal/sinu-vertebral/sinus vertebral nerve
the outer lamellae of the annulus fibrosus at the posterior part of the intervertebral disc
What forms the anterior neural plexus of the vertebral column
fibers from the ventral primary ramus
what forms the lateral neural plexus of the vertebral column
fibers from ventral primary ramus white ramus communicans paradiscal ramus communicans gray ramus communicans
What is the name given to the white ramus communicans which becomes embedded within the annulus fibrosus of the intervertebral disc
