Which part of the vertebrae supports most of the weight of the vertebral column?

Which part of the vertebrae supports most of the weight of the vertebral column?

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 part of the vertebrae transmits weight?

Because of the anterior concavity of the spine in the thoracic region, weight is transferred from the posterior to the anterior column through the inclined pedicles and in the lumbar region, where the concavity is posterior, a part of the compressive force of the anterior column is transmitted to the posterior.

What is the major weight-bearing part of the vertebra?

The body is the disc-shaped anterior portion, and is the weight-bearing area of a vertebra.

What part of the vertebra supports the weight of the structures above it?

The body is the anterior portion of each vertebra and is the part that supports the body weight. Because of this, the vertebral bodies progressively increase in size and thickness going down the vertebral column.

What part of the vertebrae supports most weight?

Lumbar vertebrae
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.

What supports the weight of the vertebrae?

Intervertebral Discs and Ligaments of the Vertebral Column. The bodies of adjacent vertebrae are strongly anchored to each other by an intervertebral disc. This structure provides padding between the bones during weight bearing, and because it can change shape, also allows for movement between the vertebrae.

Where is the weight bearing part of the vertebral column?

Lumbar Vertebrae (L1 – L5)

The lumbar vertebrae graduate in size from L1 through L5. These vertebrae bear much of the body’s weight and related biomechanical stress. The pedicles are longer and wider than those in the thoracic spine. The spinous processes are horizontal and more squared in shape.

What part of the vertebrae transfers weight?

The specific portion of the vertebrae that supports and transfers weight along the axis of the spine is called the body.

Which vertebrae bear most of the weight?

lumbar vertebrae
The lumbar vertebrae are labeled L1 to L5. This area is the most prone to injury, because it bears the most weight when you sit, stand, push, pull or lift. Below the lumbar spine area is a series of fused bones known as the sacrum.

What part of the vertebrae bears weight?

The lumbar vertebrae are the some of the largest and heaviest vertebrae in the spine, second in size only to the sacrum. A cylinder of bone known as the vertebral body makes up the majority of the lumbar vertebrae’s mass and bears most of the body’s weight.

What part of vertebrae is weight-bearing?

lumbar
The lumbar region, commonly called the lower back, consists of five vertebrae labeled L1 to L5. This is the main weight-bearing section of the spinal column.

What part of vertebrae is weight bearing?

Intervertebral Discs and Ligaments of the Vertebral Column. The bodies of adjacent vertebrae are strongly anchored to each other by an intervertebral disc. This structure provides padding between the bones during weight bearing, and because it can change shape, also allows for movement between the vertebrae.
