Final answer:
A sagittal section of the human brain reveals key structures like the cerebrum, cerebral cortex, corpus callosum, and the longitudinal fissure. It also shows the division into the frontal, parietal, temporal, and occipital lobes, each with specific functions.
Step-by-step explanation:
The sagittal section of the human brain is a vertical cut that divides the brain into left and right halves. It can feature various brain structures such as the cerebrum, which includes the cerebral cortex, the white matter of the corpus callosum, and the longitudinal fissure that separates the cerebral hemispheres. The cerebral cortex itself exhibits folds called gyri and grooves called sulci, which help to increase the area available for neurons.
The cerebrum is further divided into four lobes: the frontal lobe, parietal lobe, temporal lobe, and occipital lobe, which are separated by different sulci such as the central sulcus and lateral sulcus. These lobes and their folds are responsible for various functions of the brain, ranging from sensory processing to decision making.
