Broca's area is made up of the pars opercularis and the pars triangularis, both of which contribute to verbal fluency, but each has its own specific contribution. The pars opercularis (BA44) is involved in language production and phonological processing due to its connections with motor areas of the mouth and tongue.
The orbital part of inferior frontal gyrus also known as the pars orbitalis is the orbital part of the inferior frontal gyrus. [1]In humans, this region is bordered by the triangular part of the inferior frontal gyrus (pars triangularis) and, surrounding the anterior horizontal limb of the lateral sulcus, a portion of the opercular part of inferior frontal gyrus (pars opercularis).
The inferior or orbital surface of the frontal lobe is concave, and rests on the orbital plate of the frontal bone. It is divided into four orbital gyri by a well-marked H-shaped orbital sulcus. These are named, from their position, the medial, anterior, lateral, and posterior, orbital gyri.
Brodmann area 45 (BA45), is part of the frontal cortex in the human brain.It is situated on the lateral surface, inferior to BA9 and adjacent to BA46.. This area in humans occupies the triangular part of inferior frontal gyrus (H) and, surrounding the anterior horizontal limb of the lateral sulcus (H), a portion of the orbital part of the inferior frontal gyrus (H).
Frontal lobe syndrome can be caused by a range of conditions including head trauma, tumours, neurodegenerative diseases, neurodevelopmental disorders, neurosurgery and cerebrovascular disease. Frontal lobe impairment can be detected by recognition of typical signs and symptoms, use of simple screening tests, and specialist neurological testing.
Inferior frontal gyrus, lat. gyrus frontalis inferior with 3 parts: pars opercularis (Brodmann area 44) pars triangularis (Brodmann area 45), and pars orbitalis (orbital part of inferior frontal gyrus) Superior temporal gyrus, lat. gyrus temporalis superior; Middle temporal gyrus, lat. gyrus temporalis medius
But my mom, who is a nurse, noticed that my white blood cell count was concerningly high, which could be a sign of infection or a bone marrow disease. This felt like a red flag, especially because ...
