Anatomy of the Spine

When encouraging or applauding someone, we always say keep it up. The spinal cord is the most important part of the human body. In fact, it is safe to say that the human body depends on this single particle. But as mentioned above, is it really possible for a person to live with a stiff spine? Let’s take a closer look at this blog.

The human spine is made up of three segments. These segments form three natural curves when viewed from the side. The c-shaped curves of the neck and the lower back, which is called the cervical spine and the lumbar spine respectively, and the reverse c-shaped curve of the chest is called the thoracic spine. Let’s understand the structure of the spine-

 

Vertebrae
The human spine is made up of small bones known as vertebrae. These are the bones, which are assembled on top of one another which creates the natural curves. The spinal cord and nerve roots get protected by these bones as they create a canal. There is a total of 7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae.

Spinal Cord and Nerves
The spinal cord travels through the middle part of each stacked vertebra, called the central canal which extends from the skull to your lower back. Nerves carry messages between the brain and muscles by branching out from the spinal cord through openings in the vertebrae.

Muscles and Ligaments
Muscles work to stabilize and support the spine. Also, the ligament keeps the spine in good shape and helps in coordination.

Intervertebral Disks
These sit in between the vertebrae. They are flat and round. These made up of two main components- Nucleus pulposus and Annulus fibrosus. These disks act as shock absorbers for the spine as they maintain the strength of the spine by expanding when required.

Facet Joints
There are small joints between the back of the vertebrae that help the human spine move. There are four facet joints associated with each vertebra. The facet joints are important as they allow rotation of the spine.

This is the anatomy of the spine. I hope this information adds value to your knowledge. Watch out this space for more such information. Greetings for SYS Medtech International PVT. LTD.

Overview of Skeleton

The human skeleton is the basic structure of the human bones that holds the human body. The human skeleton is made up of many different types of bones and cartilage. Fibrous tissues called ligaments and tendons are also part of the skeleton. In this blog, we are going to get information about these bones and their structure.

Like other vertebrate species, the human skeleton has two main subdivisions, these are- axial and appendix. The axial includes the vertebral column, which is the spine and most of the skull. The appendix consists of the pelvic and pectoral lumbar and cartilage of bones. The third subdivision is visceral which includes the lower jaw, the upper jaw, and branched arches with the hyoid bone. Each subdivision has specific characteristics.

The human skeleton has three main functions- support, protection and motion. Of these functions, support is the most primary and basic function of the skeleton which might be the reason for its existence. All internal organs, systems and muscles depend on skeletal support.

After that, the human skeleton protects the internal organ from severe damage. For eg. the rib cage protects the lungs and heart, the skull protects the brain, etc. Looking at these examples we can surely say that the development of the human skeleton is the most important part of the evolution of mankind.

The third common function of the skeleton is the motion. Every muscle in the body is linked to the skeleton. Thus, from a beautiful straight drive by Sachin Tendulkar to the strokes on canvas by an artist and from the adventurous expeditions made by ISRO astronauts to the potter who works hard to make pottery, the movements of the body and its organs have been made possible by independent engineering systems of muscles and bones.
