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

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 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
