Which of the following is NOT a spinal bone type?

The scapula is not classified as a type of spinal bone. Instead, it is a flat bone that serves as the attachment point for many muscles and plays a key role in the shoulder joint. The scapula is commonly referred to as the shoulder blade and is vital for movement and stability in the shoulder area.

On the other hand, the coccyx, sacral, and thoracic are specific types of vertebrae that make up the spine. The coccyx, or tailbone, consists of the last few vertebrae that fuse together, supporting the pelvis. The sacral vertebrae, which also fuse to form the sacrum, are located below the lumbar vertebrae and are integral to the structure of the pelvis. Thoracic vertebrae are the 12 vertebrae located in the upper and mid-back region, each connecting to a pair of ribs, providing support and enabling movement of the upper body. This categorization of bone types is essential for recognizing the distinctions between different parts of the skeleton and their functions in the human body.
