When viewed from the anatomic position the natural curve of the lumbar spine is classified as what type?

Is the lumbar spine concave or convex?

Spinal curves

The neck (cervical) and low back (lumbar) regions have a slight concave curve, and the thoracic and sacral regions have a gentle convex curve (Fig. 1).

When does lumbar curve develop?

The cervical curve forms when the infant is able to hold up his or her head (at three or four months) and sit upright (at nine months). The lumbar curve forms between twelve to eighteen months when the child begins to walk.

What anatomical vertebral structure is unique to the lumbar spine?

Typical lumbar vertebrae have several features distinct from those typical of cervical or thoracic vertebrae. The most notable distinction is the presence of a large vertebral body. The spinous process is short and thick, relative to the size of the vertebra, and projects perpendicularly from the body.

What parts of the spine are concave?

Sacrum and Coccyx – The 9 lowest vertebrae become fused into 2 bones. The five sacral bones are convex and the 4 coccygeal bones are concave.

What type of curve does the lumbar spine have?

The thoracic spine curves outward, forming a regular C-shape with the opening at the front—or a kyphotic curve. The lumbar spine curves inward and, like the cervical spine, has a lordotic or backward C-shape.

Why does the lumbar curve develop?

Secondary curves in the cervical and lumbar spine develop as infants become able to lift their heads, sit up, crawl, stand, and walk. As children grow, their spine continues to develop natural curves into a normal, mature spine.

Which curves are primary and which are secondary?

The vertebral column is curved, with two primary curvatures (thoracic and sacrococcygeal curves) and two secondary curvatures (cervical and lumbar curves).

How do the spinal curves help in maintaining balance?

The spinal curves

The spine’s curves work like a coiled spring to absorb shock, maintain balance, and to facilitate the full range of motion throughout the spinal column (see Anatomy of the Spine).
