Cerebrospinal fluid passes through choroidal villi to enter the superior sagittal sinus.
False
The visual cortex is located in the _________ lobe.
Frontal
Which lobe of the cerebrum is responsible for planning and initiating voluntary motor movement?
Frontal Lobe
Which of these regions of the brain regulates body temperature, hunger, and thirst?
Hypothalamus
Neural centers that control heart rate, respiration, and blood pressure are located in the
Medulla
In which brain region are the cerebral peduncles located?
Midbrain
A shallow groove on the surface of the cerebral cortex is called a
Sulcus
Which of these regions is the largest part of the diencephalon and forms the upper and lateral walls of the third ventricle?
Thalamus
How are the right and left cerebral hemispheres specialized for different functions?
The left cerebral hemisphere has greater control over math and language.
The pituitary gland (hypophysis) is connected to the hypothalamus and receives regulatory impulses that control the secretion of hormones.
True
The subarachnoid space lies between what two layers of meninges?
arachnoid and pia
Trace the path of circulation of cerebral spinal fluid (CSF) from production to absorption.
choroid plexus, ventricles of the brain, subarachnoid space, arachnoid villi, superior sagittal sinus
The tough, dense fibrous connective tissue meningeal layer is the
dura mater
The sheet of dura mater that separates the right and left cerebral hemispheres is the
falx cerebri
Areas of the cerebral cortex involved with the initiation of motor impulses are localized to the posterior aspect of the __________.
frontal lobe
Which of these lobes of the cerebrum lies anterior to the central sulcus?
frontal lobe
The falx cerebri passes through the _________.
longitudinal fissure
The brain stem consists of the
midbrain, medulla, and pons.
Damage to which region of the brain would result in someone being unable to identify an item in his or her pocket by touch alone?
somatosensory association cortex
Cerebrospinal fluid is located within the
subarachnoid space.
If a person's corpus callosum was severed __________.
that person would experience a lack of communication between the right and left cerebral hemispheres
Which areas of the brain are most likely to process and store motor skill memories?
the premotor cortex, basal ganglia, and cerebellum
A "motor homunculus" can be visualized as an overlay on the precentral gyrus. The reason why the facial region of this homunculus covers such a large surface area is because
we have very expressive faces
