Use pages 224-233 to answer the following questions.
Per:
1. The largest part of the human brain is the (paired)
are the
. The other major subdivisions of the brain
,
, and the
in the brain are called
. The cavities found
and they are filled with
.
2. Circle the terms indicating the structures that are not part of the brain stem.
Cerebral hemispheres
Midbrain
Medulla
Pons
Cerebellum
Diencephalon
3. A
is an elevated ridge of cerebral cortex tissue. The convolutions seen in the cerebrum are
important because they increase
matter is composed of
. Gray matter is composed of
. White
, which provide for communication between different parts of the brain as
well as with lower CNS centers.
4. Figure 1 is a diagram of the right lateral view of the human brain. First, match the letters on the diagram with the
following list of terms and insert the appropriate letters in the answer blanks. Then, select different colors for each of
the areas of the brain with a color-coding square and use them to color in the coding squares and corresponding
structures in the diagram. If an identified area is part of a lobe, use the color you selected for the lobe but use strips for
that area.

6. Referring to the brain areas listed above, match the appropriate brain structure with the following descriptions.
________________
________________
________________
________________
________________
Site of regulation of water balance and
body temperature.
Contains reflex centers involved in
regulating respiratory rhythm in
conjunction with lower brain-stem
centers.
Forms the cerebrospinal fluid.
Important relay station for afferent
fibers traveling to the sensory cortex for
interpretation.
Connects the third and fourth ventricles.
________________
Large fiber tract connecting the cerebral
hemispheres.
________________
Contains autonomic centers, which
regulate blood pressure and respiratory
rhythm, as well as coughing and
sneezing centers.
________________
Responsible for regulation of posture
and coordination of skeletal muscle
movements.
________________
Secretes melatonin and is involved with
the sleep-wake cycle and some aspects
of mood.
________________
Secretes nine major hormones.
7. Mark true or false for each of the following statements. If the statement is false, correct the underlined term by
inserting the correct term in the answer blank.
The primary sensory area of the cerebral hemisphere(s) is found in the precentral gyrus.
Cortical areas involved in audition are found in the occipital lobe.
The primary motor area in the temporal lobe is involved in the initiation of voluntary movements.
A specialized motor speech area located at the base of the precentral gyrus is called Wernicke’s area.
The right cerebral hemisphere receives sensory input from the right side of the body.
Damage to the thalamus impairs consciousness and the awake/sleep cycles
