Question 1
The Brain
1. List the four parts of the human brain.
The human brain is made up of the cerebral hemispheres, diencephalon, brain stem, and
cerebellum.
2. Describe the number, location and function of the brain ventricles.
There are four ventricles in the interior of the brain, chambers filled with cerebrospinal
fluid which is produced there.
3. Label the ventricles.
See figure in module.
4. Describe the brain meninges and the layers.
The meninges are three layers of connective tissue membranes that cover and protect
central nervous system organs and enclose cerebrospinal fluid. The leathery dura mater is
the double-layered outer meninx. The middle arachnoid meninx is a loose layer separated
from the dura mater by the subdural space. Beneath the arachnoid meninx is the
subarachnoid space which contains blood vessels and is filled with cerebrospinal fluid.
The inner pia mater meninx is a thin connective tissue tightly attached to the brain.
5. What is the function of the choroid plexus?
The choroid plexus produces cerebrospinal fluid.
6. What is the blood-brain barrier and how is it maintained?
The blood-brain barrier is a diffusion barrier which prevents most particles from entering
the central nervous system tissue, keeping the brain and spinal cord separate from
general blood circulation. The blood-brain barrier is formed by the relatively impermeable
brain capillaries, due to the glial cells astrocytes. Maintenance of the blood-brain-barrier
is important to provide a stable chemical environment for the nervous system. A stable
internal environment is important to protect neurons from chemical variations which
could cause uncontrollable firing of neurons.
7. Describe the cerebrum.
The cerebrum, the foremost part of the brain, is the largest part of the brain in humans
comprising about 83% of total brain mass

, 8. What is the median longitudinal fissure?
It separates the left and right cerebral hemispheres from one another.
9. Raised ridges on the cerebrum are called____.
Gyri
10. The _______ separates the cerebrum from the cerebellum.
The transverse fissure



Question 2
The Brain
11. The outer portion of the cerebral hemispheres is called the ______and is highly
convoluted and gray in color.
Cerebral cortex
12. Describe the functions of the lobes of the cerebrum.
The frontal lobe controls higher level executive functions such as reasoning and decision
making. The frontal lobe also controls motor functions and permits control over voluntary
muscle actions. The parietal lobe receives sensory information from receptors in the
mouth for taste and located in the skin, such as those for touch, pressure, and pain. The
occipital lobe interprets visual input. The temporal lobe has sensory areas for hearing and
smelling.
13. What is the difference between a primary area and an association area in the brain?
Primary areas in each lobe receive information for one type of sensory information.
Association areas act mainly to integrate more than one type of sensory information for
purposeful action.
14. Label the regions of the cerebral cortex.
See figure in module.
15. List the three major parts of the brain stem.
The brain stem is made up of the mid-brain, pons, and medulla oblongata.
16. How is the medulla oblongata involved with the heart and lungs?
The medulla oblongata regulates heartbeat and breathing
