Lumbar Spine: In your low back, you have 5 vertebrae that are labeled L1 to L5 (the ‘L’ means lumbar). Some people have 6 lumbar vertebrae. These vertebrae are your largest and strongest vertebrae, responsible for carrying a lot of your body’s weight.
Which vertebrae has the largest body?
L5 has the largest body and transverse processes of all vertebrae. The anterior aspect of the body has a greater height compared to the posterior. This creates the lumbosacral angle between the lumbar region of the vertebrae and the sacrum.
Which vertebrae have large vertebral bodies?
Lumbar vertebrae have very large vertebral bodies, which are kidney shaped. They lack the characteristic features of other vertebrae, with no transverse foramina, costal facets, or bifid spinous processes. However, like the cervical vertebrae, they have a triangular-shaped vertebral foramen.
What vertebrae is thickest?
The intervertebral discs are largest and thickest in the lumbar region, because these vertebrae carry the bulk of the body’s weight. The discs are thinnest in the upper thoracic region.
Which vertebrae is the strongest?
Lumbar Spine: In your low back, you have 5 vertebrae that are labeled L1 to L5 (the ‘L’ means lumbar). Some people have 6 lumbar vertebrae. These vertebrae are your largest and strongest vertebrae, responsible for carrying a lot of your body’s weight.
What are the top 7 vertebrae called?
Regions of the Spine
Cervical (neck)- the top seven vertebrae/bones are called C1-C7. Thoracic (upper back)- the next 12 vertebrae/bones are called T1-T12. Lumbar (lower back)- the next five vertebrae/bones are called L1-L5.
Which vertebrae does not have a body?
The atlas (C1 vertebra) does not have a body or spinous process. It consists of an anterior and a posterior arch and elongated transverse processes.
What is the difference between vertebrae and vertebra?
As nouns the difference between vertebra and vertebrae
is that vertebra is any of the small bones which make up the backbone while vertebrae is ; the bones that make up the spinal column.
What is the difference between vertebrae and spinal cord?
The vertebral column surrounds the spinal cord which travels within the spinal canal, formed from a central hole within each vertebra. The spinal cord is part of the central nervous system that supplies nerves and receives information from the peripheral nervous system within the body.
How many curves should have a person have?
A healthy back has three natural curves: An inward or forward curve at the neck (cervical curve) An outward or backward curve at the upper back (thoracic curve)
What separates the vertebrae in life?
The bodies of the vertebrae are separated from each other by intervertebral discs. The body is mainly spongy bone and red marrow, but the margins of the upper and lower surfaces consist of a ring of compact bone, the vertebral end-plates.
Why does the human vertebral have four curves?
The human vertebral column has four curves (or arches) to help support theupright posture. … If humans had a perfectly straight backbone, we would have major pains such as arthritis throughout the spine because there will be no distribution of weight and more pressure on the bones.
What is the weakest part of the spine?
The weakest part of the spine is the cervical spine, which is made up of seven vertebrae.
What vertebrae breaks the worst?
While all spinal cord injuries (SCIs) can be dangerous and life-altering to the people who suffer them, there is one variety of spinal cord injury, in particular, that is considered the worst: an injury that falls within the cervical spinal cord — specifically at the C1 and C2 spinal cord injury level.
What are the symptoms of L5 nerve damage?
Compression or inflammation of the L5 and/or S1 spinal nerve root may cause radiculopathy symptoms or sciatica, characterized by:
- Pain, generally felt as a sharp, shooting, and/or searing feeling in the buttock, thigh, leg, foot, and/or toes.
- Numbness in the foot and/or toes.
