Divisions of Spinal Segments

Segmental Spinal Cord Level and Function
Level	Function
Cl-C6	Neck flexors
Cl-T1	Neck extensors
C3, C4, C5	Supply diaphragm (mostly C4)
C5, C6	Shoulder movement, raise arm (deltoid); flexion of elbow (biceps); C6 externally rotates the arm (supinates)
C6, C7, C8	Extends elbow and wrist (triceps and wrist extensors); pronates wrist
C7, C8, T1	Flexes wrist
C8, T1	Supply small muscles of the hand
Tl -T6	Intercostals and trunk above the waist
T7-L1	Abdominal muscles
L1, L2, L3, L4	Thigh flexion
L2, L3, L4	Thigh adduction
L4, L5, S1	Thigh abduction
L5, S1 S2	Extension of leg at the hip (gluteus maximus)
L2, L3, L4	Extension of leg at the knee (quadriceps femoris)
L4, L5, S1, S2	Flexion of leg at the knee (hamstrings)
L4, L5, S1	Dorsiflexion of foot (tibialis anterior)
L4, L5, S1	Extension of toes
L5, S1, S2	Plantar flexion of foot
L5, S1, S2	Flexion of toes

Spinal cord injury, or myelopathy, is a disturbance of the spinal cord that results in loss of sensation and mobility. The two common types of spinal cord injury are:

• Trauma : automobile accidents, falls, gunshots, diving accidents, etc.
• Disease : polio, spina bifida, tumors, Friedreich's ataxia, etc.

It is important to note that the spinal cord does not have to be completely severed for there to be a loss of function. In fact, the spinal cord remains intact in most cases of spinal cord injury.

Spinal cord injuries are not the same as back injuries such as ruptured disks, spinal stenosis or pinched nerves. It is possible to "break one's neck or back" and not sustain a spinal cord injury if only the vertebrae are damaged, but the spinal cord remains intact.
