What is the gyrus rectus?
The gyrus rectus, or straight gyrus, is located at the most medial margin of the inferior surface of the frontal lobe 1,2. Its function is unclear but it may be involved in higher cognitive function (e.g. personality) 3.
Where is the gyrus rectus?
frontal lobe
The gyrus rectus (or straight rectus) is located inferomedially on the frontal lobe. Its function is unclear but it may be involved in higher cognitive function (e.g. personality).
What artery supplies gyrus rectus?
It goes down and forward to the gyrus rectus and usually enters the GR mesial surface from its origin. The orbitofrontal artery is usually a single vessel at the GR posterior third and it gives off small branches which are distributed to the gyrus basal surface from mesial to lateral and from posterior to anterior.
What is the function of the orbital gyrus?
Central Lobes & Frontal Lobes – Inferior View On the inferior surface of the brain, locate the orbital gyri of the frontal lobe; so named because they are located just above the skull’s bony orbits. The function of the orbital gyri is related to intellectual and emotional expression.
What is the gyri and sulci?
Gyri and sulci are the folds and indentations in the brain that give it its wrinkled appearance. Gyri (singular: gyrus) are the folds or bumps in the brain and sulci (singular: sulcus) are the indentations or grooves.
What is a cingulate gyrus?
The cingulate gyrus is an arch-shaped convolution situated just above the corpus callosum. The frontal portion is termed the anterior cingulate gyrus (or cortex). A component of the limbic system, it is involved in processing emotions and behavior regulation. It also helps to regulate autonomic motor function.
What is the anatomy of the gyrus rectus?
Gross anatomy. The gyrus rectus is bounded medially by the interhemispheric fissure and wraps around to the inferomedial surface of the frontal lobe, where it is separated from the rostral gyrus by the inferior rostral sulcus 5. Inferolaterally it is separated from the medial orbital gyrus by the olfactory sulcus.
Where is the rectus of the brain located?
The gyrus rectus is bounded medially by the interhemispheric fissure and wraps around to the inferomedial surface of the frontal lobe, where it is separated from the rostral gyrus by the inferior rostral sulcus 5.
Where is the straight gyrus located in the brain?
The gyrus rectus, or straight gyrus, is located at the medial most margin of the inferior surface of frontal lobe 1,2. Its function is unclear but it may be involved in higher cognitive function (e.g. personality) 3. Article:
What is a gyrus?
What is a gyrus? A gyrus (plural: gyri) is a ridge on the surface of the brain. Each ridge is surrounded by fissures known as sulci (singular: sulcus). Gyri are unique structures that have an important evolutionary function; they increase the surface area of the brain up to an impressive 2000 centimeters squared.
