Basic info on the br
Term | Definition |
---|---|
cerebral hemisphere | the two halves that make up the cerebrum |
longitudinal fissure | a large separation in the cerebrum; separated the two hemispheres |
cerebral cortex | continuous layer of gray matte4; outer layer of the cerebrum |
corpus callosum | white matter deep within the cerebrum; provides communication between the two hemispheres |
What is the cerebrum comprised of? | cerebral cortex, basal nuclei, basal forebrain, and limbic cortex |
basal nuclei | cognitive processing. most importantly, those associated with planning movements |
basal forebrain | has nuclei important for learning and memory |
limbic cortex | region of the cerebral cortex that is part of the limbic system |
gyri | wrinkled ridge |
sulcus | the grooves between two gyri |
lateral sulcus | deep groove that separates the frontal and parietal lobes from the temporal lobe; anatomical landmark |
central sulcus | deep groove that separates the frontal lobe from the parietal lobe |
parieto-occipital sulcus | deep groove separating the parietal and occipital lobes |
longitudinal fissure | a deep obvious line that separates the two hemispheres |
The meninges | the four membranes that envelop the brain and the spinal cord. |
Meninges from superficial to deep | dura mater, arachnoid mater, and pia mater |
choroid plexus | the network of blood vessels and ependymal cells on surface of the ventricles |
Brain stem | thalamus, midbrain, Pons, and medulla oblongata. These structures connect the brain to the spinal cord. |
Midbrain | Coordinates sensory representations of the visual, auditory, and somatosensory perceptual spaces |
Pons | forward-facing bulge in the brainstem |
Thalamus | top of the midbrain |
Medulla oblongata | connects to the spinal cord |
