The term "centrum semiovale" refers to a part of the brain. It is spelled with the IPA phonetic transcription /sɛntrəm ˌsɛmiˈoʊveɪli/. The first part of the word, "centrum," is pronounced with a "k" sound, as in "kitten." The second part, "semiovale," is pronounced with a "semi" that sounds like "sem-eye" and an "ovale" that sounds like "oh-vuh-lee." This word can be difficult to spell due to the various vowel sounds and the combination of Latin and Greek roots.
The term "centrum semiovale" refers to a structure located in the white matter of the brain. It is a region situated in the cerebral hemispheres above the lateral ventricles. The name "centrum semiovale" is derived from Latin, where "centrum" means center and "semiovale" translates to half-oval shape.
Anatomically, the centrum semiovale is characterized by its semi-oval or ellipse-shaped appearance and is primarily composed of myelinated nerve fibers. These fibers are responsible for transmitting signals between different areas of the cerebral cortex and subcortical structures. The centrum semiovale functions as a connection pathway, promoting communication between various regions of the brain.
Due to its central location, the centrum semiovale is vulnerable to damage in certain neurological conditions. For instance, it can be affected by white matter lesions, which are commonly observed in diseases like multiple sclerosis. Damage to the centrum semiovale can lead to disruptions in the transmission of nerve signals, impacting cognitive abilities, motor function, and sensory processing.
Understanding the anatomy and function of the centrum semiovale is crucial for professionals in the medical field, particularly neurologists and radiologists. Knowledge of this structure allows for a more accurate interpretation of brain imaging studies, aiding in the diagnosis and treatment of various neurological disorders.
Semioval center, medullary center, the great mass of white matter at the center of each cerebral hemisphere, as seen on horizontal section at the level of the callosum; this is called sometimes the major semioval center, the minor semioval center being the figure presented on section about two centimeters above this level.

The term "centrum semiovale" is derived from Latin and has roots in both Greek and Latin.
"Centrum" in Latin means "center" or "core", referring to the central part of something. In this context, it represents the central region of the brain.
"Semiovale" combines the Latin word "semi", meaning half or partial, and "ovale", meaning oval or egg-shaped. It refers to the shape of the centrum semiovale, which resembles a partial oval structure.
Therefore, "centrum semiovale" can be translated as the "partial oval center". It describes the central whitish matter of the brain, primarily composed of myelinated nerve fibers that radiate outwards from the internal capsule.
