A direct relationship exists between the level of cord injury and the degree of respiratory dysfunction, as follows: With high lesions (ie, C1 or C2), vital capacity is only 5-10% of normal, and cough is absent, With lesions at C3 through C6, vital capacity is 20% of normal, and cough is weak and ineffective, With high thoracic cord injuries (ie, T2 through T4), vital capacity is 30-50% of normal, and cough is weak, With lower cord injuries, respiratory function improves, With injuries at T11, respiratory dysfunction is minimal; vital capacity is essentially normal, and cough is strong. Your injury might make it more difficult to breathe and cough if your abdominal and chest muscles are affected.

For example, in the quadriceps reflex (patellar tendon reflex), the afferent signal from the stretch in the patellar tendon is sent back to the spinal cord, where the afferent neuron synapses on the alpha motor neuron ofthe quadriceps muscle causing it to contract. The spinal cord itself is organized into a series of tracts or neuropathways that carry motor (descending) and sensory (ascending) information. Dysesthesias, especially those in the upper extremities (eg, sensation of burning in the hands or arms), are common. Thats a lot to learn! ; There are over 200 types of cancer.
