Which group of vertebrae has both cervical and thoracic vertebrae?

The correct choice identifies the vertebral regions of the spinal column. The human spine is divided into several segments, with the cervical region consisting of 7 vertebrae located in the neck, and the thoracic region comprising 12 vertebrae in the upper and mid-back area. By stating that there are 7 cervical and 12 thoracic vertebrae, this answer accurately reflects the number of each type of vertebra within their respective regions of the spine.

Understanding the spinal anatomy is crucial for various practices in healthcare, as different regions of the spine serve distinct functions and have specific characteristics. Cervical vertebrae are smaller and allow a greater range of motion for the head and neck, while thoracic vertebrae are larger and provide attachment points for ribs, playing a critical role in protecting the thoracic organs.
