The human vertebral column is made up of 33 bones:
There are four curves in the spine. They are the Cervical, Thoracic, Lumbar and Pelvic curves.
Thoracic and sacral curves are present at birth also known as primary curves
The adult spine has four curves: the cervical curve (neck), thoracic curve (upper back), lumbar curve (lower back), and sacral curve (pelvic region). These curves provide structural support, enabling the spine to absorb shock and distribute mechanical stress during movement. They also help maintain an upright posture and balance the body's weight over the pelvis, contributing to overall stability and flexibility. Additionally, the curves facilitate efficient movement and protect the spinal cord and nerves.
The spinal curves that assist in allowing a child to walk and run are the cervical, thoracic, lumbar, and sacral curves. These curves help maintain balance and support the body's weight, enabling upright posture and locomotion. The development of these curves is crucial as they provide stability and flexibility, facilitating movements such as walking and running as the child grows.
A spinal curve refers to the natural or abnormal curvature of the spine. The spine typically has four natural curves: cervical, thoracic, lumbar, and sacral, which help with balance and movement. Abnormal spinal curves, such as scoliosis, kyphosis, or lordosis, can lead to discomfort, pain, and potential mobility issues. Proper alignment and curvature are essential for overall spinal health and function.
The thoracic and sacral curves are the primary curves, as they are obvious at birth. The cervical and lumbar curves are secondary as they are modifications on the foetal position.

The spinal column features primary and secondary curves that each serve distinct functions. Primary curves, which include the thoracic and sacral curves, are present at birth and accommodate the shape of the fetal spine, providing space for internal organs. In contrast, secondary curves, such as the cervical and lumbar curves, develop later in life as a result of weight-bearing activities and upright posture, enhancing balance and support. Together, these curves contribute to the overall stability and flexibility of the spine.
there are 3 curves
In the fetal and neonatal spine, the vertebral column curves of the cervical, thoracic, lumbar, and sacral all oriented as anterior concave curves. and are designated primary curves. To get the state legislature to adopt rules that require sequential lineups
