Lecture Unit 3: CNS
The location of conscious thought processes and the origin of all complex intellectual functions is the
Cerebrum
The major pathway of communication between the right and left hemisphere is/are the
Corpus Callosum
Of the five cerebral lobes, the one not visible on the surface of the brain is the
Insula
The primary gustatory cortex is part of the (taste)
Insula
The portion of the adult brain that includes the cerebrum is derived from which secondary brain vesicle?
Telencephalon
The blood-brain barrier is made up of
astrocyte perivascular feet and capillary endothelial cells
Arrange the cerebral lobes visible on the superior surface of the brain in the correct anterior-posterior order. a: Parietal b: Frontal c: Occipital
b, a, c or frontal -> parietal -> occiptal
Cerebrospinal fluid is formed by the
choroid plexus

fourth ventricle
Which structures form the lentiform nucleus?
Globus Pallidus + Putamen
Which secondary brain vesicle forms the portion of the adult brain that includes the epithalamus, thalamus, and hypothalamus?
Diencephalon
What is the correct order for the cranial meninges, from superficial to deep? a: Dura mater b: Pia mater c: Arachnoid
Dura Mater, Arachnoid, Pia Mater
The primary motor cortex is part of the
Frontal Lobe
The portion of the brain involved primarily with vision is the
Occipital Lobe
The primary somatosensory cortex is part of the
Parietal Lobe
A sickle-shaped vertical partition that divides the left and right cerebellar hemispheres is the
falx cerebelli
A brain ventricle located in the cerebrum is the ________ ventricle.
lateral ventricle
Dural venous sinuses are areas where
the meningeal and periosteal layers separate to form large blood-filled spaces.
A brain ventricle located in the diancephalon is the ________ ventricle.
third ventricle
