What are the 3 processes found on the bone?
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.
