I believe what you are talking about is the sacrum? It's just below the spine in the pelvic area..
This is called the sacrum.
Sacrum
the individual bones of the spine are called "Vertebrae"
The Coccyx bone, which is a very small triangular bone forming the end part of the spine. It is actually 4 separate bones which are fused into one.
Each bone in my spine is called one "vertebra". Two or more are called "vertebrae".
The bones in your back are called vertebrae but all of them together are called the spine, the neck is cervical, mid-spine is thoracic and the lower spine is the lumbar.
The ankle-bone is called the talus. It sits below the two leg bones, the tibia and the fibula.

the answer is the sacrum
This bones is called the Coccyx. It is the last bone on the spine.
The bone that forms the back bone is the spine. The spine is composed of vertebrae. It is the chief support of organizing the nervous system.
Each bone in my spine is called one "vertebra". Two or more are called "vertebrae".
The sacrum, which consists of 5 fused bones, and the coccyx are below the lumbar vertebrae in the spine.
Your "backbone" is actually a series of bones; the technical name is "spinal column", and it's a stack of bones called "vertebrae" connected by cartilage and muscles that allow it to bend and twist. At the bottom of the spine, the vertibrae connect to the pelvis, or "hip bones", which then connect to the thigh, the upper leg bones. The lowermost bone in the spine is the coccyx, or tailbone. If we had tails, that's where they would be connected.
The bones in your back are called vertebrae but all of them together are called the spine, the neck is cervical, mid-spine is thoracic and the lower spine is the lumbar.
back bone spine
The bone above your patella is called your femur.The bones below your patella are called your tibiaand fibula.
about 8 bone
