Study Notes
- The brain has four regions: the cerebrum, diencephalon, brainstem, and cerebellum.
Cerebrum
- Largest part of the brain.
- Responsible for higher brain functions like conscious thought and intellectual processing.
- It is divided into two hemispheres by the longitudinal fissure.
- The outer layer is the cerebral cortex, composed of grey matter.
- Deep to the cortex is cerebral white matter.
- Gyri are folds or hills on the surface.
- Sulci are depressions.
- Fissures are deep depressions.
- The cerebrum's deep fissures are lateral and longitudinal.
- A 5th lobe, known as the insula, is internal to the others and associated with memory and taste.
- The assignment of tasks to specific locations in the cerebral cortex is not precise
- There are three general functional areas: sensory, motor and association areas.
- Sensory areas process information from sensory receptors like eyes, ears, nose, tongue and skin.
- Motor areas control voluntary movement.
- Association areas integrate sensory input and help in making action decisions.
Frontal Lobe
- Anterior part of the brain and separated from the Parietal lobe by the Central Sulcus
Parietal Lobe
- Posterior to the Frontal Lobe and separated by the Central Sulcus
- The Parieto-occipital sulcus separates it from the Occipital Lobe
Temporal Lobe
- Has a superior border marked by the lateral sulcus which is also known as the lateral fissure.
- Is involved in hearing and smell.
Occipital Lobe
- Posterior part of the brain
Association Areas
- The premotor cortex is the somatic motor association area.
Diencephalon
- The diencephalon consists of the epithalamus, thalamus, and hypothalamus.
- The thalamus relays all messages, except smell, to the cerebral cortex.
- The hypothalamus coordinates nervous and endocrine systems.
- The epithalamus contains the habenular nucleus and pineal gland.
Brain Stem
- The brain stem consists of the midbrain, pons, and medulla oblongata.
- The midbrain, also known as the mesencephalon, controls stimuli information regarding sights and sounds and processes some reflex reactions.
- The pons, which is part of the metencephalon, assists and connects regions.
- The medulla oblongata, also konwn as the myelencephalon, controls the pace of breathing, heart rate, and blood pressure.
Cerebellum
- Involved in sensory-motor coordination, comparison, and prediction.
- Arbor vitae is the cerebellar white matter.
- The cerebellum brings sensory and motor information to and from the brain.
