Final answer:
Bulbar palsy refers to the damage to the motor neurons in the brainstem, while pseudo bulbar palsy is caused by damage to the corticobulbar tracts. The primary difference between the two is the location of the damage.
Step-by-step explanation:
Bulbar and pseudo bulbar palsy are both conditions that affect the motor system. The main difference between the two is the location of the damage.
Bulbar palsy refers to the damage to the motor neurons in the brainstem, specifically the nuclei that control the muscles of the head and neck. This can result in swallowing difficulties, speaking difficulties, and weakness in the muscles of the face.
Pseudo bulbar palsy, on the other hand, is caused by damage to the corticobulbar tracts, which are the pathways that connect the motor cortex in the brain to the cranial nerve nuclei in the brainstem. This can lead to similar symptoms as bulbar palsy, but there may also be additional symptoms like emotional outbursts and exaggerated reflexes.
