GYRUS CINGULI Meaning and
Definition
-
Gyrus cinguli, also known as the cingulate gyrus, is a prominent structure found in the brain that is involved in the limbic system, which is responsible for emotions, learning, and memory processes. The term "gyrus" refers to a ridge or fold in the cerebral cortex, or outer layer of the brain, while "cinguli" means "belt" in Latin, describing its belt-like shape surrounding the corpus callosum.
The gyrus cinguli is located in the medial aspect of the cerebral hemispheres, situated above the corpus callosum and beneath the parietal and frontal lobes. It is divided into two major components: the anterior cingulate cortex (ACC) and the posterior cingulate cortex (PCC), which are connected by a thin band of nerve fibers called the cingulum.
The anterior cingulate cortex is involved in various cognitive functions, such as decision-making, attention, and error detection. It also plays a significant role in regulating emotions and pain perception. On the other hand, the posterior cingulate cortex is involved in memory retrieval, spatial orientation, and self-reflection.
The gyrus cinguli is interconnected with several other brain regions, including the hippocampus, amygdala, and prefrontal cortex, forming a complex network that coordinates and integrates emotional and cognitive processing. Dysfunction or abnormalities within this region have been implicated in various neuropsychiatric disorders, including depression, anxiety, schizophrenia, and Alzheimer's disease.
In summary, the gyrus cinguli is a belt-like ridge in the brain that plays a crucial role in emotional regulation, cognitive processes, memory retrieval, and spatial orientation.

Convolution of the cingulum, callosal convolution, g. fornicatus (of the older nomenclature), a long, curved convolution arching over the corpus callosum, from which it is separated by the sulcus corporis callosi; on its upper surface it is bounded by the sulcus cinguli and (posteriorly) by the sulcus subparietalis; it forms the upper part of the limbic lobe, or g. fornicatus.

Etymology of GYRUS CINGULI
The word "gyrus cinguli" comes from Latin.
1. Gyrus: The word "gyrus" derives from the Latin term "gyrus", which translates to "fold" or "twist". In anatomy, it refers to the folds or convolutions in the cerebral cortex, which contribute to increasing its surface area.
2. Cinguli: The term "cinguli" is derived from the Latin word "cingulum", which means "girdle" or "belt". It refers to a band or girdle-like structure. In the context of the brain, the "cinguli" specifically refers to the cingulate gyrus, a prominent structure located in the cerebral cortex.
Hence, the term "gyrus cinguli" is a Latin phrase used in anatomy to describe the cingulate gyrus, a particular fold or convolution in the cerebral cortex.
