Front 1

The meninges are the outer coverings of what structures?

Back 1

Brain and Spinal Cord

Front 2

Name the three meninges starting with the outermost layer.

Back 2

1) Dura Mater - Outermost layer, strongest and thickest
2) Arachnoid Mater - Middle layer, thin membrane sncloses the subarachnoid space
3) Pia Mater - Innermost layer, follows contour of cortex, composed of 2 layers: highly vascular and sheaths blood vessels as they enter the brain

Front 3

What is the cerebrospinal fluid (CFS) filled space between the arachnoid mater and the pia mater?

Back 3

Subarachnoid space

Front 4

What does the corpus callosum connect?

Back 4

The right and left cerebral hemispheres

Front 5

Name the main structures that compose the brainstem.

Back 5

The brainstem contains nuclei for most of the crainal nerves and connects critical pathways in the brain and spinal cord to the entire body. It is subdivided into the:
1) Medulla
2) Pons
3) Midbrain

Front 6

The central sulcus is the boundary between what two lobes?

Back 6

The central sulcus (Rolando fissure) is the boundary between the frontal and parietal lobes, and the transition zone between the primary motor and primary somatosentory cortex.

Front 7

Where is the primary motor cortex (Brodmann's area 4) located in the brain?

Back 7

precentral gyrus in the frontal lobe. This gyrus is directly anterior to the central sulcus (Rolando fissure). It is the cortical area from which movements are most easily elicited and the source of about one third of the corticospinal tract.

Front 8

Where is the motor speech area (Broca's area) located in the brain?

Back 8

inferior frontal gyrus in the frontallobe in the dominant hemisphere (usually the left hemisphere)

Front 9

Where is the primary somatosensory cortex located in the brain?

Back 9

postcentral gyrus of the parietal lobe. This gyrus is directly posterior to the central sulcus (Rolandic fissure).

Front 10

Where is the receptive speech area (Wernicke's area) located in the brain?

Back 10

In the supramarginal and angular gyri of the parietal lobe, also includes adjoining regions of the temporal and occipital lobes, in the dominant hemisphere ( usually the left hemisphere).

Front 11

The basal ganglia is composed of _________.

Back 11

a group of subcortical nuclei, most prominently including the putamen, globus pallidus, and caudate nucleus.

Front 12

Where is the primary visual cortex (Broadmann's area 17) located?

Back 12

calcarine sulcus
