BASIRRHINAL GYRUS Meaning and
Definition
-
The basirrhinal gyrus is a specific region located within the brain, specifically in the limbic system. It is an anatomical structure found in the temporal lobe, more precisely within the piriform cortex. This region plays a critical role in olfaction, which refers to the sense of smell.
The term "basirrhinal" comes from two Greek words: "basis," meaning "step," and "rhinion," meaning "the point where the nose begins." This designation is appropriate since the basirrhinal gyrus is located near the base of the brain, close to the nasal cavity.
The basirrhinal gyrus functions as a primary processing center for olfactory information. It receives input from olfactory receptors located in the nasal cavity, which detect various chemical stimuli in the environment. These receptors send signals to the basirrhinal gyrus, where the olfactory information is integrated and analyzed.
Furthermore, the basirrhinal gyrus is involved in the formation of memories associated with smells. This region has connections to other brain areas involved in memory, such as the hippocampus and amygdala. It plays a crucial role in linking olfactory information with emotional experiences, allowing for the formation of smell-related memories and associations.
Overall, the basirrhinal gyrus is an essential brain structure responsible for the processing and perception of smells, as well as the encoding of smell-related memories.
Etymology of BASIRRHINAL GYRUS
The etymology of the word "basirrhinal" comes from the combination of two words: "basi-" and "rhinal".
The prefix "basi-" is derived from the Greek word "basis", meaning "the base" or "the bottom". In the context of the brain, it refers to the lowermost part or base.
The term "rhinal" is derived from the Latin word "rhinus", which means "pertaining to the nose".
When combined, "basirrhinal" refers to a region in the brain that is located at the base and is associated with the nose.
The term "gyrus" comes from the Latin word "gyrus", meaning "circle" or "coil". In neuroanatomy, it refers to the convolutions or folds of the brain's cerebral cortex.
