-
The thin partition that separates the first and second ventricles is the:
septum pellucidum
-
What structure is covered by many blood vessels and adheres tightly to the surface of the brain?
pia mater
-
Cerebrospinal fluid:
is secreted by ependymal cells
-
Ependymal cells work to:
- - adjust the composition of CSF

- - remove waste products from CSF
- - secrete CSF into the ventricles
-
The layer of the meninges that closely follows every gyrus and sulcus is the:
pia mater
-
The medulla oblongata regulates:
blood pressure and respiration
-
The cardiovascular reflexes are based in the:
medulla oblongata
-
Overseeing the postural muscles of the body and making rapid adjustments to maintain balance and equilibrium are functions of the:
cerebellum
-
The cerebellar hemispheres are separated by a band of cortex called the:
vermis
-
The presence of many large, highly-branched Purkinje cells in a sample of brian tissue indicates that it cam from the:
cerebella cortex
-
The medulla oblongata relays auditory information to the:
inferior colliculi
-
Nerve fiber bundles on the ventrolateral surface of the mesencephalon are the:
cerebral penduncies
-
The reflex movement of the head toward a loud noise is directed by the mesencephalon. Which nuclei accomplish this?
inferior colliculi
-
Which structure connects the left and right cerebral hemispheres?
corpus callosum
-
What structure secrets the hormone melatonin?
pineal gland
-
What are properties of the mamillary bodies?
- - located in posterior hypothalamus
- - shaped like little breasts
- - control reflex eating movements
- - process olfactory information
-
What are the functions of the hypothalamus?
- - secretes oxytocin
- - produces ADH
- - regulates body temperature
- - controls autonomic centers
-
The anterior nuclei of the thalamus:
are part of the limbic system
-
The posterior nuclei of the thalamus include:
lateral and medial geniculate nuclei
-
What is the function of the thalamus?
process sensory information and relay it to the cerebrum
-
The _____ filters and relays sensory information to the cerebral cortex.
thalamus
-
What are properties of the limbic system?
- - functions in emotions, learning, and memory
- - located between the border of the cerebrum and diencephalon
- - contains cerebral and diencephalic components

-
Divisions of the cerebral hemispheres that are named after the overlying skull bones are:
lobes
-
The regions of the cerebral cortex superior to the lateral sulcus is/are the:
parietal and frontal lobes
-
The surface of the postcentral gyrus contains the _____ cortex.
primary sensory
-
Difficulties in estimating temporal relationships between events may stem from damage to:
the prefrontal cortex
-
Gustatory information reaches the brain by way of:
cranial nerve IX
-
The cranial nerve that innervate the eye muscles are:
III, IV, and VI

Which sensations does the vestibulocochlear nerve carry?
hearing and equilibrium
-
At the optic chiasm:
axons from the nasal halves of each retina cross
-
The tympanic reflex:
restricts the movement of auditory ossicles
