Atlas (C1) does not have a spinous process or body
The skeletal system is the anchor and lever system that the muscles pull against to cause locomotion.spinous process and transverse processThe bones are the leavers against which the muscles pull.In reference to the axial skeleton, the spinous process and the transverse process are the leavers against which the muscles pull.Superior articular process
Posteroinferiorly extends from the top of the vertebral arch
No it doesn't. The atlas is the first cervical vertebra and the only one with no spinous process.
Cervical vertebrae have a bifurcated spinous process.
This part projects posteriorly.
Lumbar vertebra has a block-like body and a short, stout spinous process.
Transverse Process and Spinous Process
The curved area between the spinous process and the transverse process.
The spinous processes of the vertebrae are origins and insertions for various postural muscles. A broken spinous process would likely result in significant pain and muscle aches due to improper alignment of the muscles.
spinous process
In the cervical spine, the C2-C6 vertebrae generally have bifid spinous proceses.
