What are two functions of the curves in the human vertebral column?
In humans this primary curve is modified by three more: (1) a sacral curve, in which the sacrum curves backward and helps support the abdominal organs, (2) an anterior cervical curve, which develops soon after birth as the head is raised, and (3) a lumbar curve, also anterior, which develops as the child sits and walks …
What are the main functions of spinal cord?
Functions
- Carrying signals from the brain: The spinal cord receives signals from the brain that control movement and autonomic functions.
- Carrying information to the brain: The spinal cord nerves also transmit messages to the brain from the body, such as sensations of touch, pressure, and pain.
What is the functions of backbone?
Your spine, or backbone, is your body’s central support structure. It connects different parts of your musculoskeletal system. Your spine helps you sit, stand, walk, twist and bend. Back injuries, spinal cord conditions and other problems can damage the spine and cause back pain.
Why are the curves of the vertebral column important?
These curves increase the vertebral column’s strength, flexibility, and ability to absorb shock. When the load on the spine is increased, by carrying a heavy backpack for example, the curvatures increase in depth (become more curved) to accommodate the extra weight. They then spring back when the weight is removed.
What are spinal curves?
Spinal curves are either kyphotic or lordotic. In a normal spine there are four types of spinal curvatures important to balance, flexibility, and stress absorption and distribution.
What kind of shape is the cervical spine?
The cervical spine curves slightly inward, sometimes described as a backward C-shape or lordotic curve 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
How is the curvature of the spine formed?
Curvature is developed and needs to be maintained The spine of an adult takes on an S curve, however this is a shape formed through development. Children are actually born with a C curve, with pronounced kyphosis until the age when they begin to crawl. As children pick their heads up, the cervical lordosis portion of the ideal S shape takes form.
Why is the curve of the vertebral column important?
The curves of the vertebral column are important because they increase its strength, help maintain balance in the upright position, absorb shock during walking and running, and help protect the spinal column from fracture.
What are the curves of the lumbar spine?
The lumbar spine curves inward and, like the cervical spine, has a lordotic or backward C-shape The curves of the spine can be exaggerated in any plane, leading to pain, deformity and neurologic dysfunction. Some abnormal curves are asymptomatic while other require treatment. Some excessive and abnormal curves are amenable to surgical treatment.

What should I know about the function of the spine?
The parts of the spine and its function are further discussed. What should I know about the spine? The spine (or backbone) runs from the base of the skull to the pelvis. It serves as a pillar to support the body’s weight and to protect the spinal cord. There are three natural curves in the spine that give it an “S” shape when viewed from the side.
