How many joints foes each vertebra have?
Each vertebra has four facet joints, one pair that connects to the vertebra above (superior facets) and one pair that connects to the vertebra below (inferior facets) (Fig. 6). Figure 6. The superior and inferior facets connect each vertebra together.
superior articular facets of the Atlantas articulate with
occipital condyles
what covered odontoid process and ligaments?
Tectorial memebrane
Tectorial memebrane
Symphysis what position
midline
Nociceceptors
No Pain
Tectorial membrane is a continuation of what structure?
PLL
Nucleus pulposus
What 2 disc anatomy consist of?
The disc anatomy consists of two main structures, the nucleus pulposus (NP) and the annulus fibrosus (AF). The nucleus pulposus is composed of water, type II collagen, chondrocyte-like cells, and proteoglycans. This unique composite allows the NP to be elastic, flexible under stress forces and to absorb compression
