Final answer:
The lobes, gyri, fissure, and sulcus are anatomical features of the brain. The brain is divided into four major lobes: frontal, parietal, temporal, and occipital. Gyri are folds on the brain's surface, while sulci are the grooves that separate them.
Step-by-step explanation:
The lobes, gyri, fissure, and sulcus are all anatomical features of the brain.
- Lobes: The brain is divided into four major lobes: frontal, parietal, temporal, and occipital. Each lobe has its own functions and is involved in various cognitive processes.
- Gyri: These are the folds or bumps on the surface of the brain. They maximize the surface area of the cerebral cortex, allowing for more neurons and gray matter.
- Fissure: A deep sulcus is called a fissure. The longitudinal fissure is the most prominent fissure, dividing the brain into left and right hemispheres.
- Sulcus: These are the grooves on the surface of the brain, separating the gyri. They form important landmarks that help identify different functional centers of the brain.
