Spinal bones are essential for supporting your body and protecting your spinal cord and nerves. This article will tell you everything you need to know about spinal bones, including their structure, function, and the diseases that can affect them.
What is a vertebra?
Spinal bones are the main structural component of the spine. But,They form the backbone, and each vertebra is made up of three types of spinal bone: dorsal (top), lumbar (middle), and sacral (bottom). These bones are inserted into a disc between the vertebrae, which provides stabilization and support.
Types of Spinal Bones
Spinal bones are small, plate-like structures that make up the backbone. They’re located in the vertebrae and protect the spinal cord. There are twelve pairs of spinal bones, each numbered from 1 to 12. The two endmost spinal bones, called the coccyx (tailbone), are usually removed when a person has surgery for cancer or another medical condition.
The cervical (neck) spine comprises seven cervical vertebrae, which curve around the upper neck like the rings of a tree trunk. Each cervical vertebra has three tall neural processes (forward-pointing spines) that connect it to its neighbor. The first cervical vertebra has two long processes that fan out forward and upward, called transverse processes. The second cervical vertebra has one long process that extends backward and downward from its back bottom edge, called an arched process. The third cervical vertebra has no protrusion and is recognized only by its number: C3.
The thoracic (chest) spine is made up of twelve thoracic vertebrae. These Anatomical bone illustrations show the location of key features on each thoracic spinal When you look at someone’s back, you’ll see twelve pairs of small bones – regions called lumbar intervertebral disks – that run between each pair of ribs on either side of your spine as well as between your shoulder blades on your upper
Spinal bones are located in the spinal cord and support the vertebral column. The vertebral column is a series of bones that make up the spine. But, each bone in the vertebral column has a name, including the vertebrae, stacked one on top of the other like poker chips.
The spinal cord is a thin, cord-like structure that runs from the base of your skull to just below your tailbone. But,the spinal cord provides nerve connections between different parts of the brain and body. The spinal cord can be damaged when diseases or accidents cause pressure on it, causing paralysis or death.
Functions of Spinal Bones
The spinal bones are the backbone of the human body. They make up a skeleton, which is held together by vertebrae. The spinal column functions as a support system for the upper body and helps to move the body around.
The five spinal bones are:
- The skull (Cranium)
- The thoracic cage (lumbar spine)
- The ribs (thoracolumbar spine)
- The pelvic girdle (sacrum)
- The hips (pelvis)
The spinal cord extends from the brain down through these bones, and each bone has many functional roles.
The connective tissue of the spine
Spinal bones are small, fragile ones in the spinal cord and spine vertebrae. The spinal cord connects the brain to the body and controls movement. The vertebrae are the HHSICUS curve bones that make up your spine. They protect your spinal cord, control your spinal motion, and support your weight.
The central backbone of the spine is form by four fused cervicals (neck) vertebrae- C1 through C4- along with their discs, ligaments, and muscles. These bones are also joined together by cartilages called intervertebral discs (IVDs). These IVDs act as shock absorbers between each of your vertebrae and allow for flexibility in the spine. Between these IVDs lies a space called the canal for Zanvier’s nerve, which provides sensation down one side of your back!
Therefore, your spinal column contains twenty-five bones: twelve thoracic (upper back), eight lumbar (lower back), five sacra (the bottommost bone in the spine), two atlanto-occipital (floating) joints, one zygapophyseal joint, and one pedicle screw connection across each level of the disc in between!
The 24 thoracics (#1 through #12) bones originate from your ribcage; these eventually fuse along the side seam to form a single piece of bone called a sternum (#13). Each subsequent thor
