The Cerebrum Flashcards
Where is gray matter in the cerebrum?
In cerebral cortex and basal nuclei
Where is white matter in the cerebrum?
Deep to basal cortex, around basal nuclei
What are the three divisions of the cerebrum? (sulci)
- The central sulcus
- The lateral sulcus
- The parieto-occipital sulcus
What divides the parietal lobe from the occipital lobe?
The parieto-occipital sulcus
What divides the frontal lobe from the temporal lobe?
The lateral sulcus
What divides the anterior frontal lobe from the posterior parietal lobe?
The central sulcus
What sulcus divides the motor and sensory areas?
The central sulcus
What part of the cerebrum directs voluntary movements?
The pre-central gyrus of the frontal lobe
What part of the cerebrum makes up the surface of the precentral gyrus?
The primary motor cortex
What are the neurons of primary motor cortex?
Pyramidal cells
Which gyrus recieves somatic sensory info (touch, pressure, pain, vibration, etc)
Postcentral gyrus of the parietal lobe
What part of the cerebrum makes up the surface of the postcentral gyrus?
Primary sensory cortex
What part of the cerebrum processes information from sight receptors?
Visual Cortex
What part of the cerebrum processes information from sound receptors?
Auditory Cortex
What part of the cerebrum processes information from odor receptors?
Olfactory Cortex
