-It connects the brain and spinal cord -The medulla oblongata relays all communication between the brain and spinal cord -It coordinates complex autonomic functions

Which of these is found in the pons?

-Respiratory control nuclei -Nuclei for four cranial nerves -Tracts to the cerebellum

Which of the following help to protect the brain?

-The CSF -The bones of the skull -The blood-brain barrier -The cranial meninges

The presence of many large, highly-branched Purkinje cells in a sample of brain tissue indicates that it came from the

Cerebellar cortex

Making rapid postural adjustments is a major function of the __________.

Cerebellum

Overseeing the postural muscles of the body and making rapid adjustments to maintain balance and equilibrium are functions of the

Cerebellum

The third and fourth ventricles are linked by a slender canal designated as the

Cerebral aqueduct

In the adult brain, which is the largest region?

Cerebrum

In each ventricle is a blood vessel network called the ________ that produces cerebrospinal fluid.

Choroid plexus

The pons is involved in all of the following EXCEPT __________.

Control of food intake (Truly involved in: -Automatically processing incoming sensations -Respiration -Connections to cerebellum)

Cardiovascular centers located in the ________ adjust the heart rate, the strength of cardiac contractions, and the flow of blood through the peripheral tissues.

Medulla oblongata

The control of heart rate and blood pressure is based in the

Medulla oblongata

The respiratory rhythmicity center is located in the

Medulla oblongata

The pons exchanges information with the cerebellum over the __________.

Middle cerebellar peduncle

What structure is covered by many blood vessels and adheres tightly to the surface of the brain?

Pia mater

The tracts that connect the cerebellum to the brain stem are located in the

Pons

Which of these is not one of the main divisions of the adult brain?

Prosencephalon (True divisions: -midbrain -diencephalon -cerebrum -pons)

The cerebrospinal fluid (CSF) circulates within the __________.

Subarachnoid space

Examination of a tissue sample from the central nervous system reveals many darkly pigmented cells. This tissue probably came from the

Substantia nigra

Injury to this center in the mesencephalon may lead to Parkinson's disease.

Substantia nigra

The tectum of the mesencephalon contains the

Superior and inferior colliculi

The cerebrum develops from the embryonic __________.

Telencephalon

Sensory information is processed and relayed to the cerebrum by the

Thalamus

Which statement is true regarding the meninges and cerebrospinal fluid of the spinal cord and brain?

The choroid plexuses are located only within the brain, not within the spinal cord.

Chambers within the brain that contain cerebrospinal fluid are called

Ventricles

The ________ provides the principal link between the nervous and endocrine systems.

Hypothalamus

The medulla oblongata relays auditory information to the

Inferior colliculi

A brain hemorrhage is life-threatening because

-The pressure increase within the space can distort and potentially damage brain tissue -The person can lose consciousness -Neurological changes will occur -Some areas of the brain will not be receiving blood

The adult human brain contains almost ________ of the body's neural tissue.

97%

The cerebrospinal fluid (CSF) leaves the central nervous system (CNS) and enters the circulation at the __________.

Arachnoid granulations

The white matter of the cerebellum forms a branching array called the

Arbor Vitae

The cells that cover the outer surfaces of CNS capillary endothelial cells are the

Astrocytes

Specialized ________ cells form the secretory component of the choroid plexus.

Ependymal

The dural fold that projects into the longitudinal fissure between cerebral hemispheres is called the

Falx cerebri

The elevated ridges of the cerebrum are called

Gyri

The inferior colliculus
