yes it's absent.
Cervical vertebrae have a bifurcated spinous process.
Lumbar vertebra has a block-like body and a short, stout spinous process.
Because it has long and prominent spinous process.
No it doesn't. The atlas is the first cervical vertebra and the only one with no spinous process.
spinous process
Posteroinferiorly extends from the top of the vertebral arch
body The most anterior part of the vertebra is the spinous process which comes off the body.
An anticlinal vertebra is a vertebra within a vertebral column which has a spinous process towards which the spines of all the other vertebrae are inclined.
C7
have long spinous process which is directed downward. transverse process and centrum serve as points of attachment for ribs
Most vertebrae have 3 processes. The spinous process, which is the one that comes straight off of your vertebral column, can actually be felt . You can feel this one particularly well at the base of your neck (this is the 7th Cervical vertebra, also known as Vertebra prominens). The very first vertebra, C1, also known at Atlas, does not have a spinous process. Each vertebra has two transverse processes which are on either side of the spinous processes. All of these processes are important for muscle attachments for movement of the head, neck and torso.
Transverse foramina (on all cervical vertebrae) and bifid spinous process on C2-C6
