Which vertebrae are stacked to form a continuous column in order from superior to inferior?
Continued From Above... The lumbar vertebrae are stacked to form a continuous column in order from superior (L1 or first lumbar vertebra) to inferior (L5 or fifth lumbar vertebra). Together they create the concave lumbar curvature in the lower back.
Which muscles are involved in the transverse process?
The transverse processes form important connection points for many muscles, including the rotatores and multifidus muscles that extend and rotate the trunk. Unlike the cervical vertebrae in the neck, the lumbar vertebrae lack the transverse foramina in the transverse processes, and also lack facets to either side of the body.
What is the region between the transverse process and the vertebral body called?
The region between the transverse process and the vertebral body is called the pedicle. The vertebrae are joined by facet joints (zygapophyseal joints), which are covered by articulating cartilage to provide smooth movements between the joint surfaces. The L4 and L5 vertebral bodies are taller in front than behind.
Which vertebrae are taller?
The L4 and L5 vertebral bodies are taller in front than behind. The upper and lower ends of each vertebral body are covered by bony endplates that help resist compressive loads placed on the spine. 2

What is the risk of degeneration of L4-L5 discs?
The L4-L5 disc is at a high risk of degeneration. This risk may be due to increased loads at the L4-L5 motion segment and decreased movement in the segments below this level.
How many bony protrusions are there in the vertebrae?
Each vertebra consists of a vertebral body in front and a vertebral arch at the back. The vertebral arch has 3 bony protrusions: a prominent spinous process in the middle and two transverse processes on either side. The region between the spinous process and the transverse process is called the lamina.
Where does the L4 nerve go?
L4 spinal nerve. The L4 spinal nerve roots exit the spinal cord through small bony openings (intervertebral foramina) on the left and right sides of the spinal canal. These nerve roots join with other nerves to form bigger nerves that extend down the spine and travel down each leg.
