\begin{tabular}{l} Question 1 \\ From top to bottom, what is the correct order of the vertebrae? \\ lumbar, thoracic, and cervical \\ cervical, lumbar, and thoracic \\ cervical, thoracic, and lumbar \\ sacral, cervical, and lumbar \\ \hline\end{tabular}

To determine the correct order of the vertebrae from top to bottom, we need to understand the anatomical arrangement of the vertebral column. The vertebral column is divided into several regions: 1. **Cervical vertebrae**: These are the topmost vertebrae, located in the neck region. There are 7 cervical vertebrae (C1 to C7). 2. **Thoracic vertebrae**: Below the cervical vertebrae, there are 12 thoracic vertebrae (T1 to T12) that correspond to the ribs. 3. **Lumbar vertebrae**: Following the thoracic vertebrae, there are 5 lumbar vertebrae (L1 to L5) located in the lower back. 4. **Sacral vertebrae**: Below the lumbar region, the sacral vertebrae consist of 5 fused vertebrae (S1 to S5) that form the sacrum. Given this information, the correct order of the vertebrae from top to bottom is: - Cervical - Thoracic - Lumbar - Sacral Now, let's evaluate the options provided: 1. **lumbar, thoracic, and cervical** - Incorrect order. 2. **cervical, lumbar, and thoracic** - Incorrect order. 3. **cervical, thoracic, and lumbar** - Correct order. 4. **sacral, cervical, and lumbar** - Incorrect order. Thus, the correct answer is: **cervical, thoracic, and lumbar**.
