arachnoid granulations
Cerebrospinal fluid enters the blood circulation at the
ependymal cells
Cerebrospinal fluid is secreted by
cerebellum
Overseeing the postural muscles of the body and making rapid adjustments to maintain balance and equilibrium are functions of the
thalamus
Sensory information is processed and relayed to the cerebrum by the
ependymal
Specialized ________ cells form the secretory component of the choroid plexus
thalamus
The ________ filters and relays sensory information to cerebral cortex.
hypothalamus
The ________ provides the principal link between the nervous and endocrine systems.
astrocytes
The cells that cover the outer surfaces of CNS capillary endothelial cells are the
vermis
The cerebellar hemispheres are separated by a band of cortex called the
blood vessels
The choroid plexus is composed of
midbrain
The structure of the brain that carries ascending sensory information to the thalamus is the
determines the routing of incoming sensory
The thalamus is often called the "air traffic controller" of the brain because it
pons
The tracts that connect the cerebellum to the brain stem are located in the
fourth
The ventricle associated with the pons and upper medulla is the
subarachnoid space

E) All of the answers are correct.
Which of the following help to protect the brain? A) the blood-brain barrier B) the bones of the skull C) the cranial meninges D) the CSF E) All of the answers are correct.
E) All of the answers are correct.
Which of the following is a function of the hypothalamus? A) produces ADH B) controls autonomic centers C) regulates body temperature D) secretes oxytocin E) All of the answers are correct.
process sensory information and relay it to the cerebrum
Which of the following is a function of the thalamus?
E) All of the answers are correct.
Which of the following is a property of the blood-brain barrier? A) The capillary endothelial cells are interconnected by tight junctions. B) It is generally permeable to lipid-soluble compounds. C) Astrocytes surround the CNS capillaries. D) It is absent in portions of the hypothalamus. E) All of the answers are correct.
D) provides ATP for impulse transmission
Which of the following is not a function of cerebrospinal fluid? A) provides cushioning for delicate neural tissues B) provides buoyant support for the brain C) acts as a transport medium for nutrients D) provides ATP for impulse transmission E) acts as a transport medium for waste products
forms the roof of the diencephalon
Which of the following is/are true of the epithalamus?
diencephalon
Which of the following lies between the cerebrum and the brain stem?
blockage of CSF circulation or excessive CSF production.
Hydrocephalus, or "water on the brain," may result from
breathing
If the pons was damaged, which of the following functions would be affected?
cerebrum
A neural cortex is found on the surface of the
more complex
As you ascend from the medulla oblongata to the cerebrum, the functions of each successive level become
medulla oblongata
Autonomic centers that control blood pressure, heart rate, and digestion are located in the
E) All of the answers are correct.
Ependymal cells work to A) surround the capillaries of the choroid plexus. B) secrete CSF into the ventricles. C) remove waste products from CSF. D) adjust the composition of CSF. E) All of the answers are correct.
medulla oblongata
The control of heart rate and blood pressure is based in the
hypothalamus
The floor of the diencephalon is formed by the
The hypothalamus is a key player in the endocrine system because
The hypothalamus is a key player in the endocrine system because

The layer of the meninges that closely follows every gyrus and sulcus is the
blood pressure and respiration
The medulla oblongata regulates
inferior colliculi
The medulla oblongata relays auditory information to the
extensiveness of the gyri and sulci
The most obvious feature that one notices about the cerebrum is the
diencephalon
The pineal gland is part of the
If CSF is not properly resorbed, the result would be hydrocephalus.
