Cerebrum and Cerebral Cortex Flashcards

Flashcards for reviewing cerebrum anatomy and function.

What are the two cerebral hemispheres?

Right and left hemispheres

What separates the right and left cerebral hemispheres?

Longitudinal Cerebral Fissure

What is located inside each cerebral hemisphere?

Lateral Ventricle

What is located outside each cerebral hemisphere?

Cerebral Cortex

Name the three types of white matter fibers.

Projection fibres, Association fibres, Commissural fibres (Corpus Callosum)

What are gyri?

Ridges on the surface of the cerebrum

What are sulci?

Grooves on the surface of the cerebrum

Name the four lobes of the brain.

Frontal, Parietal, Temporal, Occipital

What sulcus separates the frontal and parietal lobes?

Central sulcus

What sulcus separates the parietal and occipital lobes?

Parieto-occipital sulcus

What fissure is located on the lateral side of the brain?

Lateral fissure

What is the genu of the corpus callosum?

The front part of the corpus callosum

What is the splenium of the corpus callosum?

The back part of the corpus callosum

What is the fornix?

A band of white matter from the hippocampus to the hypothalamus

What is the septum pellucidum?

A membrane separating the anterior horns of the lateral ventricles.

How many layers are there in the neocortex?

Six layers

What is the outermost layer of the cerebral cortex?

Molecular layer

Name a distinct feature about the molecular layer.

It contains no neurons

Name the layer of the neocortex that contains densely packed stellate cells and small pyramidal cells.

External granular layer

Name the layer of the neocortex that contains loosely packed stellate cells and medium pyramidal cells.

External pyramidal layer

Name the layer of the neocortex that contains densely packed stellate cells only.

Internal granular layer

Name the layer of the neocortex that contains only large pyramidal cells.

Internal pyramidal layer
