The meninges and subarachnoid space surround the brain in the following order, beginning with the outer layer:
dura mater, pia mater, arachnoid membrane, subarachnoid space
dura mater, arachnoid membrane, subarachnoid space, pia mater
pia mater, dura mater, subarachnoid space, arachnoid membrane

Cerebrospinal fluid is produced by the
meninges.
subarachnoid space.
choroid plexus.
ventricles.
After cerebrospinal fluid has circulated through the brain and subarachnoid space it is
excreted by the kidneys.
recirculated for the next three hours.
reabsorbed into the blood supply.
transported through the central canal to the abdomen.
In the central nervous system neurons develop
on the inner surface of the embryonic hollow tube.
in radially oriented glial cells.
in the chambers which become the ventricles of the brain.
in cortex of the brain.
The three major parts of the brain are the
telencephalon, the diencephalon, and the metencephalon.
cerebral cortex, the association cortex, and the brain stem.
frontal lobe, the parietal lobe, and the temporal lobe.
forebrain, the midbrain, and the hindbrain.
Neurons that do not establish synaptic connections with a postsynaptic cell
migrate to the bone marrow.
may have an insufficient number of growth cones.
may later become malignant.
eventually die.
The lateral fissure separates the _____lobe from the _____ lobe.
frontal; parietal
frontal; temporal
temporal occipital
parietal; occipital
The corpus callosum connects the
two hemispheres of the brain.
structures of the limbic system.
pituitary gland and the hypothalamus.
thalamus and the hypothalamus.
The most important structures of the limbic system are the limbic cortex, the
hippocampus, and the amygdala.
basal ganglia, and the thalamus.
primary motor cortex, and the primary association cortex.
hypothalamus, and the pituitary gland.
The limbic system plays a role in
planning and execution of movement.
visual and auditory functions.
control of the endocrine system.
emotional behavior, learning, and memory.
The _____ surrounds the third ventricle and its two most important structures are the _____.
forebrain; the telencephalon and the diencephalon
diencephalon; thalamus and the hypothalamus
limbic system; basal ganglia and the amygdala
diencephalon; fornix and the massa intermedia
The thalamus is responsible for
most of the neural input received by the cerebral cortex.
emotional behavior.
movement of a particular part of the body.
behaviors related to survival of the species.
Neurons in the hypothalamus
control the peripheral nervous system.
send projection fibers through the optic chiasm.
are controlled by hormones secreted by the anterior pituitary gland.
are involved behaviors such as fighting and fleeing.
The anterior pituitary gland produces
vasopressin.
oxytocin.
gonadotropic hormones.
estrogen.
The principal structures of the tectum are the
superior and inferior colliculi.
hippocampus and amygdala.
thalamus and hypothalamus.
lateral and medial geniculate nuclei.
The reticular formation
relays visual information from the retina to the rest of the brain.
appears as four bumps on the brain stem.
is one of two major fiber systems within the brain.
plays a role in sleep and arousal.
The periaqueductal gray matter is so called because of an abundance of
fibers.
cell bodies.
synapses.
axons.
The spinal cord is _______________ the vertebral column.
fused to

preganglionic nerve.
hypoglossal nerve.
vagus nerve.
trigeminal nerve.
The two divisions of the autonomic nervous system are the
brain and the spinal cord.
somatic nervous system and the autonomic nervous system.
sympathetic division and the parasympathetic division.
spinal nerves and the cranial nerves.
__________ __________ leave the spinal cord through the ventral root.
