Sep 29, 2022 · The human brain is often sectioned (cut) and viewed from different directions and angles. Each point of view provides an altered perspective of the brain that changes the appearance of the major divisions, landmarks, and structures.
Feb 20, 2024 · The brain consists of billions of neurons (nerve cells) that communicate through intricate networks. The primary functions of the brain include processing sensory information, regulating bodily functions, forming thoughts and emotions, and storing memories.
In a sagittal view, the central sulcus runs ventrally about half the length of the brain. The other groove worth noting is the lateral fissure . This one runs roughly along the anterior-to-posterior direction, and curves gently dorsally.
The coronal or frontal plane is a vertical plane and splits the brain into front and back sections. The sagittal plane is a vertical plane which splits the brain into left and right sections. The horizontal or axial plane is a horizontal plane which splits the brain into upper and lower sections.
Small, almond-shaped structures, an amygdala is located under each half (hemisphere) of the brain. Included in the limbic system, the amygdalae regulate emotion and memory and are associated with the brain’s reward system, stress, and the “fight or flight” response when someone perceives a threat.
A coronal section is parallel to the vertical plane and a midcoronal section would divide the head into anterior and posterior halves (Figure 1.19). The sagittal section is also parallel to the vertical plane, but a midsagittal section would divide the head into right and left halves.
