What is a vertibray?

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.

Where is the vertebrae?

The vertebrae are the bony building blocks of the spine. There are seven cervical vertebrae in the neck, twelve thoracic vertebrae in the upper back, and five lumbar vertebrae in the lower back.

What does the vertebral body do?

The vertebral body is the main portion of the vertebra. It bears about 80 percent of the load while standing and provides an attachment for the discs between the vertebrae. The front or anterior section of the vertebral body protects the spinal cord and nerve roots.

What are the 7 vertebrae?

It consists of 7 bones, from top to bottom, C1, C2, C3, C4, C5, C6, and C7. In tetrapods, cervical vertebrae (singular: vertebra) are the vertebrae of the neck, immediately below the skull. Truncal vertebrae (divided into thoracic and lumbar vertebrae in mammals) lie caudal (toward the tail) of cervical vertebrae.

What are the 33 vertebrae?

Vertebrae. Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. ... The neck has the greatest range of motion because of two specialized vertebrae that connect to the skull.

How many vertebrae do humans have?

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 are 3 types of vertebrae?

The vertebrae are divided into three groups. There are seven cervical vertebrae (names C1 through C7), twelve thoracic vertebrae (named T1 through T12), and five lumbar vertebrae (named L1 through L5).

What is the difference between vertebra and vertebrae?

What is the difference between Vertebra and Vertebrae? Vertebra is a single bone while vertebrae are the collection of all those vertebral bones together. In other words, one vertebra is the basic building unit of the vertebrae or the backbone. Vertebra is very small compared to vertebrae.

Is the vertebrae the spine?

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.

What is the vertebral canal?

The vertebral canal, otherwise known as the vertebral cavity or spinal cavity, is an anatomical space formed by the vertebral column that stores an integral portion of the central nervous system: the spinal cord and the spinal nerve roots branching off the spinal cord bilaterally.

Where is the vertebrae in the back?

The lumbar spine has five vertebral bodies, labeled L1-L5, that extend from the lower thoracic spine to the sacrum at bottom of the spine. The vertebral bodies of the lower back are the largest of the spine and they bear the majority of the body's weight.

What are the two bones that stick out in lower back?

The vertebral column of the lower back includes the five lumbar vertebrae, the sacrum, and the coccyx.

What C7 called?

The seventh cervical vertebra, C7, also known as the vertebra prominens, shares similar characteristics of the like typical cervical vertebra C3-C6, but has some distinct features making it one of the atypical vertebrae.

Where is your C4?

The fourth cervical vertebra (C4) is centrally located in the cervical (or neck) region of the spinal column. This is just above the thoracic vertebrae. Together, the C4 and C5 vertebrae are also located in close proximity to the thyroid cartilage.
