List the four parts of the human brain - The human brain is made up of the cerebral hemispheres,
diencephalon, brain stem, and cerebellum
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
Label the ventricles - see image
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
What is the function of the choroid plexus? - produce cerebrospinal fluid
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
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
What is the median longitudinal fissure? - It separates the left and right cerebral hemispheres from one
another
Gryi - raised ridges on the cerebrum
Transverse fissure - separates the cerebrum from the cerebellum
, cerebral cortex - outer portion of the cerebral hemispheres, highly convoluted and is gray
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 functions. 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 love interprets visual input. The temporal lobe has sensory areas for hearing and smelling
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
Label the regions of the cerebral cortex - see image
List the three major parts of the brain stem - The brain stem is made up of the mid-brain, pons, and
medulla oblongata
How is the medulla oblongata involved with the heart and lungs? - The medulla oblongata regulates
heartbeat and breathing
How is the pons involved with the eyes and ears? - The pons regulates head movements in response to
visual and auditory stimuli
Where the superior and inferior colliculi are located on the posterior portion of the ______ - Midbrain
How is the hypothalamus involved with the internal environment of the body and the endocrine system
in particular - The hypothalamus maintains homeostasis, the constancy of the internal environment and
controls the pituitary gland and serving as a link between the nervous and endocrine system
All except what sensory impulses are channeled through the thalamus? - sense of smell
What is the function of the pineal body? - secretes melatonin to control the wake-sleep cycle
Describe the location and structure of the cerebellum - The cerebellum, below and at the back of the
brain, is convoluted and divided into two hemispheres with deep fissures subdividing it into three lobes
The major function of the cerebellum is to control what type of body function? - The cerebellum acts to
coordinate body movements. The cerebellum is also involved with planning movements, maintaining
balance, controlling certain eye movements, maintaining normal muscle tone and maintaining posture
What portion of the cerebellum coordinates limb movements? - Intermediate lobe, vermis
What areas of the brian does the limbus system connect? - the frontal lobes, the temporal lobes, the
thalamus, and the hypothalamus
What is the purpose of the amygdala? - The amygdala is a small portion of the limbic system that is
involved in emotions such as rage and anger
