What is the spine?

The spine (aka backbone) is a linked column of bones running from the head down to the lower back. Bone segments form the column. One bone segment is a vertebra, and multiple bone segments are vertebrae. Ligaments and muscles connect these vertebrae, and a disc separates most of the vertebrae and acts like a cushion to absorb shock along the spine. Each vertebra is numbered and grouped into 5 regions. Diagram.
  1. There are 7 cervical vertebrae in the cervical region.
  2. There are 12 thoracic vertebrae in the thoracic region.
  3. There are 5 lumbar vertebrae in the lumbar region.
  4. There are 5 sacral vertebrae, which are fused as one bone and known as the sacrum, in the sacral region.
  5. There are 3 to 5 coccygeal vertebrae, which are fused as one bone and known as the coccyx (commonly known as the tailbone), in the coccygeal region.

Overview of the Nervous System
University of Texas Medical School at Houston developed this electronic course in neuroscience that features such as interactive graphics, animations, hyperlinks, computer-assisted interactive laboratories and interactive exam reviews. The material is designed for first-year medical students, but would also be appropriate for graduate students as well as advanced undergraduates. It has also been optimized to be accessible to individuals with various backgrounds in the neurosciences and different learning styles. Ideally, readers should have had college-level courses in physics, chemistry and biochemistry, and biology.
