Spinal Cord Like the brain, the spinal cord is covered by three layers of tissue (meninges). The spinal cord and meninges are contained in the spinal canal, which runs through the center of the spine. In most adults, the spine is composed of 26 individual back bones (vertebrae). Just as the skull protects the brain, vertebrae protect the spinal cord. The vertebrae are separated by disks made of cartilage, which act as cushions, reducing the forces generated by movements such as walking and jumping.

Spine There are 5 major regions of the spine: 1  Cervical: The 7 vertebrae in the neck form the cervical region of the spine. 2  Thoracic: The 12 vertebrae in the chest region form the spine’s thoracic region.  Lumbar: The 5 vertebrae in the lower back form the lumbar region of the spine. Lumbar vertebrae are even larger and stronger than thoracic vertebrae, but are more flexible due to the lack of ribs in the lumbar region. All of the upper body’s weight bears down on the lumbar vertebrae, leading to many back problems in this region despite the size and strength of the vertebrae.

Cervical Spine Anatomy and Neck Pain Neck anatomy is a well-engineered structure of bones, nerves, muscles, ligaments and tendons. The cervical spine (neck) is delicate-housing the spinal cord that sends messages from the brain to control all aspects of the body-while also remarkably flexible, allowing movement in all directions, and strong.

Spine Basics The first seven vertebrae form the cervical spine . The mid back, called the thoracic spine , consists of 12 vertebrae. The lower portion of the spine, called the lumbar spine , is usually made up of five vertebrae. However some people have a sixth lumbar vertebra. The normal spine has an S-like curve when looking at it from the side. This allows for an even distribution of weight.

Anatomy of the Spine â Upper Back, Lower Back and Neck Anatomy of the Spine – Upper Back, Lower Back and Neck. An inside look at the structure of the back. When most people mention their back, what they are actually referring to is their spine. The spine runs from the base of your skull down the length of your back, going all the way down to your pelvis. It is composed of 33 spool-shaped bones called vertebrae, each about an inch thick and stacked one upon another.

Spine Spine. Stretching down the midline of the trunk from the base of the skull to the coccyx, the spine plays an extremely important role in our bodies as it supports the upper body’s weight; provides posture while allowing for movement and flexibility; and protects the spinal cord. Lumbar: The 5 vertebrae in the lower back form the lumbar region of the spine. 2  Lumbar vertebrae are even larger and stronger than thoracic vertebrae, but are more flexible due to the lack of ribs in the lumbar region.

Degenerative Disc Disease and Sciatica The bony spine is designed so that vertebrae stacked together can provide a movable support structure. The spine also protects the spinal cord (nervous tissue that extends down the spinal column from the brain) from injury. Each vertebra has a a bony arch behind the spinal cord that shields the cord's nerve tissue.

This page The spine is comprised of several small bones, called vertebrae, stacked on top of each other. The purpose of the vertebrae is to establish the structure of the spine. In between each vertebra is a disc and a joint, which allow the vertebrae (and ultimately the spine) to move and bend easily.

Understanding Spinal Anatomy: Overview of the Spine Typically, the spine is divided into four main regions: cervical, thoracic, lumbar and sacral. Each region has specific characteristics and functions. Cervical Spine. The neck region of the spine is known as the Cervical Spine. This region consists of seven vertebrae, which are abbreviated C1 through C7 (top to bottom). These vertebrae protect the brain stem and the spinal cord, support the skull, and allow for a wide range of head movement. The first cervical vertebra (C1) is called the Atlas.

What is the Spine? It consists of a stack of bones — 33 vertebrae, the sacrum, and the coccyx — and the intervertebral discs separating the bones. The spine is subdivided into regions known as the cervical, thoracic, and lumbar, with the pelvic region containing the sacrum and coccyx considered a separate entity.

Osteoporosis and Your Spine Home › Patients › Fractures/Fall Prevention › Exercise/Safe Movement › Osteoporosis and Your Spine. Your spine is made up of small bones called vertebrae. The picture of the spine shows the different regions of the spine, from the bottom (sacrum) to the top (cervical). People with osteoporosis most often break bones in the upper (thoracic) spine. When these bones break, they can cause pain, height loss and stooped or hunched posture, called kyphosis.

Sacral spine overview Sacral Spine. Sections. The sacral spine refers to the five fused vertebrae (S1-S5) at the end of the spinal column. Basically, the sacral spine is located behind the pelvis, between the hip bones and connects the spinal column to the pelvis. This general area is sometimes referred to as the lumbosacral spine.

A Patient's Guide to Anatomy and Function of the Spine The spinal cord is a column of nerves that connects your brain with the rest of your body, allowing you to control your movements. Without a spinal cord, you could not move any part of your body, and your organs could not function. This is why keeping your spine healthy is vital if you want to live an active life.

Anatomy of the Spine â Upper Back, Lower Back and Neck Although the spine is a continuous structure, it is often described as if it were five separate units. These units are the five different sections of the spine: 1. The cervical spine – the neck and upper back, composed of the seven vertebrae closest to the skull.

Spinal Cord Anatomy The spinal cord is a soft bundle of nerves that extends from the base of the brain to the lower back. It runs through the spinal canal and is protected by the bones of the spine (vertebrae). Messages between the brain and the nerve roots travel up and down the spinal cord, making it possible for the brain and body to communicate. The discs cushion the vertebrae and provide flexibility to the spine and spinal cord.
