What is the last vertebrae called?

Below the sacrum is the tail end of your spine, called the coccyx or tailbone. Again, several fused vertebrae (generally 3–5) form the coccyx.

What is the last cervical vertebrae called?

Unique Vertebra: C7 When feeling the back of the neck, the C7 vertebra’s spinous process (bony hump) sticks out more than the other cervical vertebrae. C7 is the bottom of the cervical spine and connects with the top of the thoracic spine, T1, to form the cervicothoracic junction—also referred to as C7-T1.

What are the 24 vertebrae?

The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused. The vertebrae in each region have unique features that help them perform their main functions.

What are the 7 vertebrae called?

cervical spine
The cervical spine is made up of 7 vertebrae. The first 2, C1 and C2, are highly specialized and are given unique names: atlas and axis, respectively. C3-C7 are more classic vertebrae, having a body, pedicles, laminae, spinous processes, and facet joints.

What is the lowest vertebrae in your back?

Vertebrae: The spine has 33 stacked vertebrae (small bones) that form the spinal canal. The spinal canal is a tunnel that houses the spinal cord and nerves, protecting them from injury. Most vertebrae move to allow for a range of motion. The lowest vertebrae (sacrum and coccyx) are fused together and don’t move.

Which vertebrae are at the very bottom of your spine?

The bottom of the spine is called the sacrum. It is made up of several vertebral bodies usually fused together as one. The remaining small bones or ossicles below the sacrum are also fused together and called the tailbone or coccyx.

What is the C spine?

About the cervical spine The cervical spine refers to the seven spinal bones (vertebrae) in the neck. It supports the head and connects to the thoracic spine. Most of the ability to turn the head comes from the top two segments of the cervical spine.

How many vertebrae are in human spine?

The average person is born with 33 individual bones (the vertebrae) that interact and connect with each other through flexible joints called facets. By the time a person becomes an adult most have only 24 vertebrae because some vertebrae at the bottom end of the spine fuse together during normal growth and development.

What is the largest bone in the spine?

The vertebrae in the lumbar spine area are the largest of the entire spine, so the lumbar spinal canal is larger than in the cervical or thoracic parts of the spine. Because of its size, the lumbar spine has more space for the nerves to move about.

Which is weakest bone in human body?

Clavicle: Clavicle, or collar bone, is the body’s softest and weakest bone. It is easy to break since it is a thin bone that runs horizontally between your breastbone and shoulder blade.
