GYRUS SUPRACALLOSUS Meaning and
Definition
-
The term "gyrus supracallosus" refers to a specific anatomical structure found in the brain. A gyrus is a ridge or fold on the cerebral cortex, the outer layer of the brain responsible for higher cognitive functions. The word "supracallosus" further specifies the location of this particular gyrus.
The gyrus supracallosus, also known as the "supracallosal gyrus" or the "paracentral lobule," is located at the superior aspect of the cerebral hemisphere, above the corpus callosum. More specifically, it is situated in the medial (middle) region of the brain. The gyrus supracallosus is divided into two parts, the anterior portion and the posterior portion, with each part performing distinct functions.
The functions of the gyrus supracallosus are closely associated with motor control and coordination. It plays a crucial role in the planning, initiation, and execution of voluntary movements and the integration of sensory information related to motor functions. The anterior portion of the gyrus supracallosus is particularly involved in the control of lower limb movements, while the posterior portion is responsible for upper limb movements.
Damage or dysfunction in the gyrus supracallosus can lead to motor deficits, impairments in coordination and balance, and difficulties with voluntary movement control. This can manifest as conditions such as hemiplegia, where one side of the body is paralyzed or weakened. Understanding the structure and function of the gyrus supracallosus is essential for diagnosing and treating motor-related disorders and improving our knowledge of the neural mechanisms underlying voluntary movement.

Etymology of GYRUS SUPRACALLOSUS
The term "gyrus supracallosus" is a combination of two terms: "gyrus" and "supracallosus".
The word "gyrus" comes from the Latin word "gyrus", which means "ring" or "circle". In anatomy, a gyrus refers to a convoluted ridge on the brain's surface, with grooves or sulci separating them. It is used to describe the various rounded folds and ridges present in the cerebral cortex.
The term "supracallosus" combines the prefix "supra-" meaning "above" or "over" and "callosus", which comes from the Latin word "callus" meaning "hard" or "thick". In this context, "supracallosus" refers to a region or area located above or over the callosum.
