What Ribs are attach individually to the sternum by way of the coastal cartilage?
Ribs 8 to 10 are attached individually to the sternum by way of the costal cartilage. Ribs 1 to 7 are attached directly to the sternum, while ribs 11 and 12 are floating ribs without any attachment to the sternum.
Why are ribs 11 and 12 known as floating ribs?
Ribs 11 and 12 are known as floating ribs because they do not attach to the sternum like the other ribs do. Instead, they are only connected to the vertebrae in the back, giving them a floating or free-end appearance.
What are irregular bones found in the spine?
Irregular bones found in the spine include the vertebrae. These bones provide support and protection to the spinal cord. The irregular shape of vertebrae allows for movement while maintaining stability in the spine.
What is attached to the backbone?
The backbone is actually a collection of spinal vertebrae, each connected to each other with a fibrous disk. On the top end, the spinal vertebrae are connected to the cervical (neck) vertebrae and then to the base of the skull. On the lower end the spinal vertebrae connect to the coccyx or tailbone which is essentially 5 fused spinal vertebrae and the central part of the pelvis (hip bone). The lower portion of the spine called the lumbar region does not connect to any additional bones. In the upper portion of the spine called the thoracic region each vertebrae also connects to two ribs. Other than connecting to additional bones, there are numerous muscles, tendons, and blood vessels that also connect to the spine. Other than the structural and limited movement role of the spine, it also serves as a vital protective role for the spinal cord which leads to all the peripheral nerves of the body.
What is the scientific name for true ribs and false ribs?
The "true" ribs are the first 8 ribs of the horse's rib cage (there are 18 total ribs). They are the true ribs because the attach to both the vertebrae above them and the sternum below. I found this in a book-Chapter 35 of Saddles by Russel H. Beatie. Hope this helps.
What organ does the backbone protect?
The spinal cord is contained within the vertebral column (backbone). Ribs attach to the vertebral column, so in that sense, you could say the contents of the thoracic cavity (lungs and heart) are also protected by the vertebrae, as ribs arise from the vertebrae. But only the spinal cord lies within the backbone itself. It does not directly protect any organs.
What 2 bones are attached to your spine?
any of the 12 pairs of ribs the pelvis

What anatomical characteristics prevent spinal cord injury as one severely bends his back in any direction?
The spinal column is a bony encasement made of movable discs, which protect the spinal cord but allow for movement. If the spine is bent too sharply the spinal column or spinal cord can be injured. http://www.brainandspinalcord.org/spinal-cord-injuries/index.html
Is a Tortoise a vertebrate invertebrate or neither?

Is the sea wasp an invertebrate?
Yes. An invertebrate is an animal without a spinal column. Jellyfish do not have spinal columns, or any skeleton of any kind.
What is function of backbone?
Essentially the same as that in any other vertebrate - including us. It is the central column of the skeleton, and the conduit for the nerve-bundle that is the spinal cord.

How do you get an erection without testicles?
As long as the nerves from the penis to the spinal column are there and undamaged then yes they can. The spinal column can be severed half way to the brain and they should still be able to get one. However, they may need some hormonal help.
