Verified step by step guidance

Understand that the human spinal cord is divided into different regions, each with a specific number of nerve pairs: cervical, thoracic, lumbar, sacral, and coccygeal.

Focus on the thoracic region, which is located in the mid-back area and is associated with the rib cage.

Recall that the thoracic region of the spinal cord is responsible for innervating the chest and abdominal muscles, as well as providing sensation to the skin in these areas.

Recognize that there are 12 thoracic vertebrae in the human spine, labeled T1 through T12, and each vertebra is associated with a pair of thoracic nerves.

Conclude that there are 12 pairs of thoracic nerves in the human body, corresponding to the 12 thoracic vertebrae.
