Detailed explanation-1: -C7 spinal cord injury and other injuries to the lower cervical vertebrae/nerves can result in paralysis and other health complications. The C6 and C7 cervical vertebrae (and the C8 spinal nerve) form the lowest levels of the cervical spine and directly impact the arm and hand muscles.
Detailed explanation-2: -The C8 nerve contributes to the motor innervation of many of the muscles in the trunk and upper limb. Its primary function is the flexion of the fingers, and this is used as the clinical test for C8 integrity, in conjunction with the finger jerk reflex.
Detailed explanation-3: -A T1 to T11 injury will affect the intercostal muscles, the muscles between the ribs. A T7 to T12 injury will affect the abdominal muscles. The body needs the diaphragm, the intercostal muscles, and the abdominal muscles to breathe and cough well.
