Paralysis of the nerve causes the diaphragm on the affected side to … Diaphragmatic Paresis: Causes, Symptoms & Treatment
The pyramidal tract is the longest nerve pathway in the body and transmits motor impulses from the first motoneuron in the brain to the second motoneuron in the spinal cord. Thus, it plays a high role in voluntary motor function and is part of the pyramidal system. Damage to the pyramidal pathway causes spastic and … Pyramidal Tract: Structure, Function & Diseases
