- The iconic gray mantle of the human brain, which appears to make up most of the mass of the brain, is the cerebrum (Figure 14.3.1). The wrinkled portion is the cerebral cortex, and the rest of the structure is beneath that outer covering.

Feb 20, 2024 · The three main parts of the brain are the cerebrum, cerebellum, and brainstem, but these portions contain many key sections. The human brain is the epicenter of our nervous system and plays a pivotal role in virtually every aspect of our lives.
Nov 9, 2023 · The human brain is a complex organ, made up of several distinct parts, each responsible for different functions. The cerebrum, the largest part, is responsible for sensory interpretation, thought processing, and voluntary muscle activity.
Two major subcortical structure systems are the limbic system and the basal ganglia, which also derive from the telencephalon. Limbic System. The limbic system is a collection of structures that border the brainstem and are located under the cerebral cortex (Figure 1.31). The word limbic is derived from the Latin “limbus,” which means border.
The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.

- Frontal lobe. Lobus frontalis. 1/4. Synonyms: none. The frontal lobe is the largest lobe of the brain comprising almost one-third of the hemispheric surface.
- Parietal lobe. Lobus parietalis. 1/6. Synonyms: none. The parietal lobe is located just underneath the parietal bone, lying posterior to the frontal lobe and anterior and superior to the temporal and occipital lobes.
- Temporal lobe. Lobus temporalis. 1/4. Synonyms: Temporal lobes. The temporal lobe largely occupies the middle cranial fossa, and its name relates to its proximity to the temporal region/bone of the skull.
- Occipital lobe. Lobus occipitalis. 1/3. Synonyms: none. The occipital lobe lies just underneath the occipital bone. It forms the most posterior portion of the brain and is found behind both the parietal and temporal lobes.
The cerebrum is the largest brain structure and part of the forebrain (or prosencephalon). Its prominent outer portion, the cerebral cortex, not only processes sensory and motor information but enables consciousness, our ability to consider ourselves and the outside world.
Anatomy of the Brain. What is the central nervous system (CNS)? The CNS consists of the brain and spinal cord. The brain is an important organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger, and every process that regulates our body.
