How do you remember vertebrae?
You can use a meal-related mnemonic to remember them – imagine a crunchy breakfast at 7 am (7 cervical vertebrae), a tasty lunch at 12 noon (12 thoracic vertebrae), and a light dinner at 5 pm (5 lumbar vertebrae).
What is the vertebra?
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 first vertebra (C1) is the ring-shaped atlas that connects directly to the skull.
What are the 4 types of vertebrae?
There are 33 vertebrae in the human spine that are split into four regions that correspond to the curvature of the spine; the cervical, thoracic, lumbar, sacrum, and coccyx.
What are the 3 main parts of a vertebra?
The normal anatomy of the spine is usually described by dividing up the spine into three major sections: the cervical, the thoracic, and the lumbar spine. (Below the lumbar spine is a bone called the sacrum, which is part of the pelvis).
What do all vertebrae have in common?
All vertebrae share a basic common structure. They each consist of an anterior vertebral body, and a posterior vertebral arch.
What are the 5 types of vertebrae?
As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx.
What is an example of a vertebra?
A vertebra is an irregular bone with some hyaline cartilage component. The spinal vertebrae include 7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae. The vertebrae at the bottom of the vertebral column are fused at maturity. Five sacral vertebrae are fused and form the sacrum.
Which vertebra has an Odontoid process?
second cervical vertebra
Axis (C2) The second cervical vertebra, or axis, supports the dens, or odontoid process, which projects rostrally from the body, serving as a pivotal restraint against horizontal displacement of the atlas.
What is the main function of the vertebral body?
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.
Which type of vertebrae are found in humans?
Humans have 7 cervical, 12 thoracic, 5 lumbar, 5 fused sacral, and 3 to 5 fused caudal vertebrae (together called the coccyx). The vertebral column is characterized by a variable number of curves.
What is backbone and where is it present in our body?
The bones, muscles, tendons, and other tissues that reach from the base of the skull to the tailbone. The backbone encloses the spinal cord and the fluid surrounding the spinal cord. Also called spinal column, spine, and vertebral column.
What are the main components of the back?
The human spine is divided into three sections: 1) the cervical spine or neck is made up of 7 vertebrae, 2) the thoracic spine made up of 12 vertebrae and 3) the lumbar spine or low back which consists of 5 vertebrae. The discs are located between each vertebra allowing for bending, twisting and shock-absorption.
