The vertebral column (backbone or spine) of a human supports approximately half the weight of the human body while muscles support the other half. The vertebral column comprises four regions: cervical, thoracic, lumbar, and sacral (or pelvic). Each region of the spine comprises various vertebral bodies separated by discs. The vertebral bodies act as a support column to hold up the spine. The vertebral column protects sensitive nerve roots while providing mobility. The vertebral column is subjected to various types of loads, particularly when a person is seated. Excessive loading of the spine over time often leads to Back pain, particularly caused by improper posture while seated.
The vertebral column is made up of 33 ring like bones calle vertebrae.It is divided into five main regions -- 7 cervical vertebrae(C1-C7) in the neck,12 thoracic (T1-T7) in the chest, 5 lumbar (L1-L5) in the lower back, 5 fused sacral vertabrae in the sacrum and 4 fused coccygeal vertebrae.
The 26 movable vertebrae are linked by movable joints. In between the bones of each joint is an intervertebral disc which is a springy pad of tough, fibrous cartilage that squashes when pressure is exerted absorbing any shocks.
Ligaments and muscles around the spine provie stability and assist with controlling muscles.
What else can I help you with?
Does a vertebra have many fixed bones?
no the vertebra column has many slightly movable bones
What are the small bones of the spinal column called?
Vertebra.
What is the OTHER name for your backbone?
Vertebral column, or vertebra.
What region of the vertebral column does this vertebra belong to?
thoracic vertebrae
How many vertebra's make up the spinal column?
In humans? 33.
What is the part of a vertebra that articulates immediately with the vertebra below it.?
The part of a vertebra that articulates immediately with the vertebra below it is called the inferior articular facet. This facet, located on the lower part of the vertebra's articular processes, connects with the superior articular facet of the vertebra beneath it, allowing for movement and stability in the spinal column.
What is the small bones of a spinal column called?
Each one is called a vertebra.
Where is the axis located on the body?
The Axis is the second vertebra in your spinal column right at the top.
What is an anticlinal vertebra?
An anticlinal vertebra is a type of spinal vertebra with a unique feature where the spinal processes align horizontally rather than vertically. This horizontal alignment can lead to complications in the spine's flexibility and movement.
What is the name for the spinal injury that occurs when a vertebra dislocates from its normal position in the spinal column?
Scoliosis
Is a polar bear a Chordata?

What is anteriolsthesis of lumbar4?
