The rib pairs that attach to the back vertebrae but are not connected to the sternum are known as floating ribs. In human anatomy, the 11th and 12th rib pairs are termed floating ribs. There are 12 pairs of ribs. The floating ribs are the lowest two rib pairs that are also called false ribs.
These are called true ribs. They each have their own cartilage connection to the sternum.
The upper back vertebrae are also known as the thoracic vertebrae.
There is only one vertebrae that is considered the axis and that is cervical vertebrae number 2 (C2). The axial skeleton is composed of the skull, facial bones, hyoid bone, the vertebrae, sacrum, and coccyx.
The tailbone, also known as the coccyx, is formed by the fusion of several small vertebrae that are no longer functional in humans. These fused vertebrae are considered vestigial remnants of our evolutionary history when our ancestors had tails. Today, the coccyx serves as an attachment point for muscles and has limited functional significance.
Your back bone is also known as the spine which is made up of 33 vertebrae, the sacrum, intervertebral discs, and the coccyx. There are three sections of vertebrae known as the; the cervical vertebrae (neck), the thoracic vertebrae (middle back) and the lumbar vertebrae (lower back).
Lipping occurs in the vertebrae as humans age. Lipping of the vertebrae is the formation of bone between the vertebrae, commonly known as bone spurs.
The spine is composed of seven unfused vertebrae in the neck region known as the cervical spine.
Lower most two pairs of ribs (11th and 12th) are known as floating ribs because they are only attached to vertebrae but not to the sternum.
The vertebrae located in the lower back are known as the lumbar vertebrae. They are the five largest and strongest vertebrae in the spinal column, situated below the thoracic vertebrae and above the sacrum. The lumbar vertebrae support the majority of the body's weight and are responsible for the flexibility and movement of the lower back.
Vertebrae
The coccyx, also known as the tailbone, is located at the bottom of the vertebral column, below the sacrum. It consists of three to five fused vertebrae and serves as an attachment site for various muscles, tendons, and ligaments.
There are 7 cervical (neck) vertebrae.Humans have seven cervical vertebrae.
