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

The brain ventricle located between the pons and the cerebellum is the ________ ventricle.

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
