Study Notes
Cerebrum and Brain Structure
- Largest part of the brain, involved in higher brain functions.
- Surface features include gyri and sulci; gyri are the raised bumps, while sulci are the grooves.
Hemispheres and Fissures
- Longitudinal fissure is a deep groove separating the brain's two hemispheres.
- Transverse fissure separates the cerebrum from the cerebellum.
Lobes of the Cerebral Cortex
- Frontal Lobe: Responsible for movement, abstract thinking, planning, memory, and judgment.
- Parietal Lobe: Located at the top and rear, processes sensory input related to touch and body position.
- Temporal Lobe: Found near the temples, primarily processes auditory information.
- Occipital Lobe: Located at the back, responsible for visual information processing.
Cerebellum and Its Features
- Known as "the little brain," situated at the lower back of the brain.
- Vermis connects the two hemispheres of the cerebellum.
- Folia are the folds of the cerebellum.
Colliculi and Corpora Quadrigemina
- Superior Colliculi and Inferior Colliculi are responsible for visual and auditory processing, respectively.
- Together, these structures comprise the corpora quadrigemina, located at the posterior brain stem.
Meningeal Layers
- Dura Mater: Tough, outer layer with two layers; anchors the central nervous system (CNS) to the skull or vertebral cavity.
- Arachnoid Mater: The middle layer of the meningeal membrane.
- Pia Mater: Inner layer closely adheres to the brain, following its contours and supplies blood vessels to nourish the nervous tissue.
