What functions are affected by a thoracic spinal cord injury?

　　Under normal circumstances, thoracic spinal cord injury may affect sensory function, motor function, autonomic nerve function, visceral function, respiratory function, and other functions. A detailed analysis is as follows:

　　1. Sensory Function

　　Thoracic spinal cord injury may cause loss or reduction of sensation below the chest area, including tactile sensation, temperature perception, and pain sensation, leading to the patient's inability to perceive external stimuli.

　　2. Motor Function

　　The nerves arising from the thoracic spinal cord innervate muscles of the chest, abdomen, and part of the lower limbs. Thoracic spinal cord injury may cause muscle weakness or paralysis in the lower limbs, affecting walking and other activities requiring lower limb strength.

　　3. Autonomic Nervous Function

　　Thoracic spinal cord injury may also affect the autonomic nervous system, leading to various autonomic dysfunctions, including blood pressure instability, abnormal heart rate, abnormal sweating, and gastrointestinal dysfunction.

　　4. Visceral Function

　　The thoracic spinal cord regulates internal organs through the sympathetic and parasympathetic nervous systems. After thoracic spinal cord injury, the functions of visceral organs such as the heart, gastrointestinal tract, and bladder may be affected.

　　5. Respiratory Function

　　Although respiratory movements are primarily controlled by the phrenic nerve arising from the cervical spinal cord to activate the diaphragm, the thoracic spinal cord also participates in the control of some respiratory muscles. Thoracic spinal cord injury, especially high thoracic spinal cord injury, can affect the function of the intercostal muscles.

　　Patients with thoracic spinal cord injury should follow medical advice for appropriate treatment to alleviate symptoms, improve prognosis, and receive necessary psychological support and rehabilitation training.
