To explain:

The region innervated by the intercostals muscles

Concept introduction:

Intercostal muscles are present in between the ribs and diaphragm and help in the process of breathing. There are different spinal nerves which innervate the different regions of the body. The thoracic nerves $\text{T1-T11}$. The nerve plexus junctions are formed by the $\text{T1}$ nerve fibers only. The movement of the limbs is coordinated by these nerves. These are called as the thoracic nerves.
