thoracic spinal cord
The thoracic spinal cord is a section of the spinal cord located in the upper and mid-back region, consisting of twelve segments labeled T1 to T12. It plays a crucial role in transmitting signals between the brain and the body, particularly for the trunk and legs. The thoracic spinal cord is responsible for controlling movements and sensations in the torso and parts of the arms.
Each thoracic segment gives rise to a pair of spinal nerves that exit the spinal column and innervate various muscles and organs. This area is also important for autonomic functions, such as regulating heart rate and blood pressure, as it connects to the sympathetic nervous system.
