Name the three meninges starting with the outermost layer.

Dura mater- outermost layer strongest and thickest arachnoid mater - middle thin membrane encloses the subarachnoid space. Pia mater- innermost layer follows contour of the cortex composed 2 layers highly vascular and sheaths blood vessels

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

the primary cortex(brodmanns area) is the precentral gyrus in the frontal lobe. this gyrus is directly anterior to the central sulcus (rolandic fissure) it is the cortical area which movements are elicited and about a third of the corticospinal tract.

Where is the motor speech area (broca's area)?

The motor speech area (brocca ara) is located in the inferior frontal gyrus in the frontal lobe in the dominant hemisphere(usually the left hemisphere.

Where is the primary somatosensory cortex located in the brain?

The primary somatosensory cortex is the postcentral gyrus of the parietal lobe. This gyrus is directly posterior to the central sulcus (rolandic fissure)

Where is the receptive speech area (wernichkes area) located in the brain?

The receptive speech area (wernickes area)is located in the supra-marginal and angular gyri of the parietal lobe also includes adjoining regions of the temporal and occipital lobes in dominate hemisphere usually left

What does the corpus callosum connect?

right and left cerebral hemispheres

The central sulcus is the boundary between what two lobes

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

The basal ganglia is composed of

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