The Anatomization Of Our Back Structure

The Anatomization Of Our Back Structure

Have you ever wondered how many muscles does our Back have? Or how many bones are there in the spinal cord? I guess you have. But it is quite difficult for a layman to understand the tough anatomical words associated with our body structure. Many of us think that studying and analysing our body and its structure is the sole job of doctors and medical students! But it is not so; you too can know the details about your back structure! How? Let’s go for the basics of our back structure first.

What is Human Back?

This is the very basic thing one should know! The Human Back or simply the Back is the wide hinder area of our body. It rises from the buttock region and goes till the back portion of the neck and spreads to the shoulder region. The back region is divided into two halves by the Backbone! The width of our back portion is usually determined by the size of our pelvis and shoulders.

The Anatomical Structure of the Back

Now once we know what we mean by the back portion, let’s move on to the anatomical structure of the back portion.

The most important part of any back structure is the spinal cord or the vertebral column or the backbone. This structure is entirely made up of bones and can be divided into mainly four parts, namely – Sacral spine, Cervical spine, Lumbar spine, Thoracic spine.

Now, these four parts have different important functions to do. Firstly, the Cervical spine consists of seven vertebrae, namely C1 – C7! There are, namely, three important functions of the cervical spine.

  1. The first and foremost important function of the Cervical spine is to support the skull’s weight.
  2. The C1 and C2 vertebrae are solely responsible for turning of the head and neck.
  3. Lastly, the C6 and C7 vertebrae help in bending and extension the head and the neck.

Secondly, the Thoracic spine is made up of 12 vertebrae, namely T1 – T12. As the main function of Thoracic spine is to protect, thus it is capable of minimal movement.

Thirdly comes the Lumbar spine; also, commonly known as the Lower Back. The main function of this is to support the trunk (torso) and help to bend over, stretch and rotate left or right at the waist level

Lastly, the Sacral spine, which is the foundation of our vertebral column or the spine. It joins the vertebral column to the pelvis. There are mainly two bones in this part – the coccyx and the sacroiliac bone.

There are three kinds of muscles in the Back, namely – Extensors, oblique, and flexors.
