The first cervical vertebra (C1) and the second cervical vertebra (C2) are atypical vertebrae due to the fact that the structures of these vertebrae are unlike the rest of the cervical spine vertebrae. The C1, also known as the atlas, is a ring-like structure which allows the beginning of the spinal cord to pass through form the base of the skull. The C2, also known as the axis, is the largest of the cervical vertebrae in vertical dimension as it contains an extension of bone called the odontoid process that extends up into the ring of the atlas. This area of the neck is the most freely moveable as the majority of side-to-side rotation occurs at C1 on C2 and is also most important neurologically as this area of the spinal cord controls heart, breathing and posture of the human being.

Why are atlas sacral and urostyle classified as a typical vertebrae?
Atlas, sacral, and urostyle vertebrae are considered typical because of their typical features for their respective regions of the spine. For example, the atlas is the first cervical vertebra that supports the skull, the sacral vertebrae fuse to form the sacrum and provide stability to the pelvis, and the urostyle is a specialized vertebra found in amphibians that supports the pelvis and hindlimbs.
What part of the spinal column is the vertebrae fused in?
sacrum and coccyx
Where is the invertebrate in the human body?
Assuming you mean vertebrae; The human spine is made up of 33 vertebrae (Sungular: vertebra.) There are four sections of vertebrae. The cervical vertebrae is is made up of 7 vertebrae and makes up the neck. The thoracic vertebrae makes up the upper back and contains 12 vertebrae. the lumbar vertebrae area makes up the lower back between the thoracic vetrtabrae and the sacral curve, made up of 5 vertebrae. Lastly, The tailbone area is below the lumbar section and called the sacral curve. 5 vertebrae make up the sacrum and 4 are fused to make the tailbone. All vertebrae but the sacral curve section are separated by invertebral discs.
NAME the 33 vertebra?
The 33 vertebrae in the human spine are divided as follows: 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral vertebrae (fused into the sacrum), and 4 coccygeal vertebrae (fused into the coccyx).
What is total number of vertebrae in the horse is approximately?
A typical horse has around 54 to 60 vertebrae in its spine. This includes 7 cervical vertebrae (neck), 18 thoracic vertebrae (chest), 6 lumbar vertebrae (lower back), 5 sacral vertebrae (pelvis), and 16-18 coccygeal vertebrae (tail). The exact number can vary slightly among individual horses.
Why are atlas sacral and urostyle classified as a typical vertebrae?
Atlas, sacral, and urostyle vertebrae are considered typical because of their typical features for their respective regions of the spine.

How does the median sacral crest on the sacrum differ from the same structure on lumbar vertebrae?
The median sacral crest on the sacrum is a bony ridge formed by fusion of sacral vertebrae, indicating where the individual vertebrae once were. In contrast, the median sacral crest on lumbar vertebrae does not exist, as lumbar vertebrae do not fuse in the same way as sacral vertebrae.
What are common problems with sacral vertebrae in horses?
Overall, sacral vertebrae problems are not common in horses. However, it is possible for the sacral vertebrae to become fractured, dislocated or infected, all of which can compress the pelvic limb spinal nerves that run through the sacral vertebrae.
A vertebrae bone is classified as?
Yes it's a bone. What else could it possibly be? There are about 33 during early development, and 26 by adulthood. Vertebrae in the sacral and coccygeal region fuse together.
How many sacral vertebrae are in a manatee?
Six
How many bones are in the sacral vertebrae?
21
What are the next set of vertebrae come after the thoracic vertebrae?
The lumbar vertebrae come next, followed by the sacral.
Which vertebrae are fused?
the sacral vertebrae, and think it's 4 to 5 that are fused together
What part of the spinal column is the vertebrae fused in?
sacrum and coccyx
What is a sacral vertebra?
A sacral vertebra is one of the bones in the spine located in the lower back, just below the lumbar vertebrae. There are typically five sacral vertebrae that are fused together to form the sacrum, which connects the spine to the hip bones. The sacral vertebrae play a role in supporting the weight of the body and protecting the spinal cord.
What is the number of vertebrae that fuse to form the sacrum is?
sacral hiatus
What are the five categories of vertebrae in your vertebral column?
The five types of vertebra are the:cervical vertebrae (neck)thoracic vertebrae (chest)lumbar vertebrae (back)sacral (pelvis)coccyx (tailbone)
