EXTRABULBAR Meaning and
Definition
-
The term "extrabulbar" is a medical adjective that refers to something or someone located or occurring outside of the bulbar region, specifically pertaining to the medulla oblongata of the brainstem. The bulbar region, also known as the bulb, is the lower part of the brainstem that connects to the spinal cord.
In a broader sense, "extrabulbar" can be used to describe any anatomical or physiological structure or process that occurs outside of the brainstem. It is often used to differentiate conditions or phenomena that are specific to this region from those that occur elsewhere in the body.
For example, in neurology, the term "extrabulbar palsy" is employed to describe paralysis or weakness of the muscles supplied by cranial nerves that originate from anywhere other than the brainstem. This condition can result from peripheral nerve damage, such as facial nerve palsy, which affects the facial muscles but not those associated with the brainstem.
Overall, "extrabulbar" is a term used to indicate that something is unrelated to or occurring outside of the bulbar region of the brainstem. Its usage is predominantly found in medical and scientific literature to denote specific anatomical or physiological characteristics or conditions.
