Of note, the L5 vertebra has the heaviest body, smallest spinous process, and thickest transverse process.
Which vertebrae have the thickest bodies?
Lumbar vertebrae support the greatest amount of body weight and thus have a large, thick body. They also have a short, blunt spinous process. The sacrum is triangular in shape.
Which vertebrae are the strongest in the body?
Some people have 6 lumbar vertebrae. These vertebrae are your largest and strongest vertebrae, responsible for carrying a lot of your body’s weight. The lumbar vertebrae are also your last “true” vertebrae; beneath this region, your vertebrae are fused by the time you stop growing.
Which vertebrae are the biggest?
The lumbar vertebrae are the biggest vertebral bones. They increase in size further down the spine in order to support the increasing weight of the body.
Which vertebrae uses the most weight?
The lumbar spine – the lower back, composed of five vertebrae, provides support for the majority of your body’s weight.
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.
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 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 is the most inferior spinal nerve?
The most inferior of the spinal nerves, the coccygeal nerve leaves the spinal cord at the level of the conus medullaris via respective vertebrae through their intervertebral foramina, superior to the filum terminale.
What is the name of the top vertebrae in your spine?
The Atlas: The Top Bone in Your Cervical Spine
The atlas is also known as C1, and while other bones in your spine are numbered in such a way (eg, the first bone is your lumbar spine is known as L1), this vertebra is much different in shape and function compared to the rest of your vertebrae.
What part of your spine controls your legs?
The lumbosacral spinal cord and nerve supply legs, pelvis, and bowel and bladder. Sensations from the feet, legs, pelvis, and lower abdomen are transmitted through the lumbosacral nerves and spinal cord to higher segments and eventually the brain.
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.
What absorbs shock in the spine?
The intervertebral discs are soft structures which act as shock absorbers between each of the vertebrae (bones) in the spine. A single disc sits between each vertebra.
What is the L spine?
The lumbar spine (lower back) consists of five vertebrae in the lower part of the spine, between the ribs and the pelvis. Lumbar spinal stenosis is a narrowing of the spinal canal, compressing the nerves traveling through the lower back into the legs.
How do you sit with a fractured vertebrae?
Push your body up off of the bed with your arms while keeping your back straight, so you come up to a sitting position on the side of your bed. At the same time, lower your legs over the side of the bed while keeping your back straight. Continue to lower your legs until your feet hit the floor, while remaining upright.
