Which of the following is not a function of the hypothalamus? |
Storing complex memories |
|
Which of the following is not a function of the medulla oblongata? |
Receiving and interpreting visual stimuli |
|
Which of the following is a function of the basal nuclei? |
Maintaining muscle tone and learned movement patterns |
|
Which division of the adult brain weighs the most? |
cerebrum |
|
The cerebrum develops from the embryonic |
telencephalon |
|
The CSF leaves the CNS and enters the circulation at the |
arachnoid granulations |
|
The CSF circulates within the |
subarachnoid space |
|
The medulla oblongata |
-lies between the spinal cord and the pons. -encloses the fourth ventricle. -relays sensory and motor information. |
|
The center in the medulla oblongata where the first synapse in the auditory pathway is made is the |
cochlear nucleus |
|
The pons exchanges information with the cerebellum over the |
middle cerebellar peduncle |
|
Which of these is found in the pons? |
-nuclei for four cranial nerves -respiratory control nuclei -tracts to the cerebellum |
|
Making rapid postural adjustments is a major function of the |
cerebellum |
|
The huge, highly branched neurons known as Purkinje cells are found in the |
cerebellar cortex |
|
Which part of the mesencephalon coordinates reflex eye movements? |
superior colliculi |
|
Injury to this center in the mesencephalon may lead to Parkinson’s disease. |
substantia nigra |
|
Which of these is not a property of the epithalamus? |
It is the roof of the fourth ventricle. |
|
The epithalamus |
-is the roof of the diencephalon. -is the location of the pineal gland. -is the location of the choroid plexus. |
|
Functions of the diencephalon? |

|
Properties of the limbic system |
-It is important in learning and memory. -It includes the hippocampus. -It is central to our ability to experience emotions. |
|
