spine 2

The thoracic vertebrae, of which there are 12, make up the middle region of the spine. They span the space between the base of the neck and the bottom of the rib cage.

Located in between the cervical spine (neck) and the lumbar spine (lower back), the thoracic vertebrae are labeled T1 to T12. The thoracic vertebrae attach directly to the rib cage.

Larger than vertebrae in the neck, thoracic vertebrae increase in size as they go down the back because they are required to support more and more weight the farther down the body they’re located. The thoracic vertebrae also have extremely prominent spinous processes, which are the large, bony knobs that protrude from the vertebral body. These processes are important for muscles and ligaments to attach to the spine. If you bend over and run your hand directly down the spine, you will be able to feel the spinous processes.

The thoracic vertebrae, and thoracic region, are unique in the following ways:

  • They attach directly to the rib cage
  • This region is less likely to sustain injury because it has the increased protection and stability of the rib cage
  • They play a large role in helping the rib cage to support the body’s organs
  • The thoracic spinal nerves help control the stomach, liver, lungs, and heart

  1. Hi
    Your blog is interesting at least for the most part.
    I have some suggestions for how you can navigate through the entries so if people want to be able to access a specific entry they don’t have to scroll down through everything to find it. There’s no real introduction to your blog or explanation of why you have one or where you intend to go with it.
    Also please be sure to proofread stuff prior to posting it. Some blog commentary involves grammar policing… And, I’m not telling you this because I think you don’t proofread them ahead of time, this is more of a warning or heads up to help you in your process. I have used blogs in the past and was involved with making blog posts for a good 3-4 years or so. I have a little idea of what you might be in for…
    And I also suggest that you visit blog sites like blogger, blogspot and live journal to gain some ideas on how you format your blog. I would like you to introduce yourself, tell us a little bit about yourself and why you’re making a blog?
    I also suggest (if you haven’t already done so); looking at blogs that are generating comments for those who have a blog as a source of revenue and are getting noticed or mentioned in various journalism, or other related arenas to help you gain insight on how how to help your blog be as successful as possible.
    When you have a good opportunity I recommend looking up this tasty life blog.
    God’s blessings and good luck to you.
    Take care.
