Significance Of The Anatomy Of The Spine

Anatomy of the spineCredit:

The anatomy of the spine is one of the greatest wonders of nature. Because of the spine, we can do incredible things. The spine is the central skeletal structure that assists in giving the body its shape and form. The spine helps in the movement of the body and it is also a weight-bearing structure. Without the spine, we will lose the strength and capability to stay upright.

Overview of the Anatomy of the Spine

The human spine is composed of 24 articulating vertebral bones. There are also 9 fused vertebral bones located in the sacrum and coccyx. The anatomy of the spine is located at the posterior aspect of the torso. The spinal column is normally categorized into three regions.

  • Cervical region - Spine anatomyCredit: region – there are 7 vertebrae in this region which are named as C1-C7. It is the closest bones to the skull and connects the head to the body. The first three cervical vertebrae allow movement of the neck. Damage to the cervical region could result to difficulty of swallowing and paralysis.
  • Thoracic region - Anatomy of SpineCredit: region – there are 12 vertebrae in this region which are named as T1-T12. The thoracic region is at the level of the lungs and part of the gastrointestinal tract. It is also in the thoracic region that the rib cage is attached which protects delicate internal organs. Damage to this region could result to difficulty of breathing.
  • Lumbar region - Anatomy SpineLumbar regionCredit: – there are 5 vertebrae in this region which are named as the L1-L5. The lumbar area is the primary weight-bearing structure of the body making them as the largest bones of the spinal column. It connects the spine to the pelvic bone. Damage to this area could result to incontinence and poor control of bowel movement.


Different Parts of the Spine

The anatomy of the spine does not consist of bones only but also ligaments, cartilages, and tendons. There are other structures that make up the spine. The body of the spine is its primary source of strength. The lamina is an extension of the body and forms a ring to contain and protect the spinal cord. The spinous process is the protrusion that you feel when you run your hand down someone’s back and it is also the area where muscles are attached.

The Anatomy of the Spine and the Spinal Cord

The most crucial function of the spine is the protection of the spinal cord. Little do people realized; the spinal cord is the extension of the brain. The spinal cord serves as a passage where billions upon billions of neural impulses travel to and from the brain. There are many nerve ending and nerve roots that run along the spinal column that help the brain control all biological processes of the body.

Summary of the Spine Anatomy

The anatomy of the spine is truly an amazing structure to behold. It consists of 24 vertebral bones which are subdivided into three categories. The different parts of the spine allow it to perform its functions efficiently.

While there are still many things to know about the spine, this article provides a fundamental foundation of knowledge. The anatomy of the spine should be studied further to help you take care and understand it.
