Sensory information is processed and relayed to the cerebrum by the

Thalamus

The layer of the meninges that closely follows every gyrus and sulcus is the

pia matter

The region of the brain responsible for predicting the consequence of events or actions is the

A) prefrontal cerebral cortex

Cortical regions that interpret sensory information or coordinate motor responses are called ________ areas.

association

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

cerebral aqueduct

The mammillary bodies of the hypothalamus

control feeding reflexes.

The thalamus is often called the "air traffic controller" of the brain because it

determines the routing of incoming sensory information to the correct cerebral cortex area.

Which of the following is a property of the blood-brain barrier? a. It is absent in portions of the hypothalamus. b. It is generally permeable to lipid-soluble compounds. c. Astrocytes surround the CNS capillaries. d. The capillary endothelial cells are interconnected by tight junctions. e. All of the answers are correct.

e. All

The only sensation that is received directly by the cerebrum is

olfaction

Olfactory receptors send axons through the cribriform plate and synapse on neurons in the

olfactory bulb.

Difficulties in estimating temporal relationships between events may stem from damage to

the prefrontal cortex.

Damage to the medulla oblongata can result in death because

the vital centers for blood pressure, heart rate, and breathing are located there.

The cerebellar hemispheres are separated by a band of cortex called the

vermis

The auditory cortex is located in the

temporal lobe

Chambers within the brain that contain cerebrospinal fluid are called

ventricles

Tic douloureux is a. a disorder of the maxillary and mandibular branches of nerve V. b. characterized by almost totally debilitating pain. c. also called trigeminal neuralgia. d. triggered by contact with the lip, tongue, or gums. e. All of the answers are correct.

e. All of the answers are correct.

The most obvious feature that one notices about the cerebrum is the

extensiveness of the gyri and sulci.

Stimulation of the ________ within the hypothalamus produces the sensation of hunger.

feeding center

The ________ is important in storage and recall of new long-term memories.

hippocampus

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

hypothalamus

Stimulation of the reticular activating system results in

increased consciousness

The medulla oblongata relays auditory information to the

inferior colliculi.

The hypothalamus is a key player in the endocrine system because

it controls the pituitary gland directly underneath it.

The optic tracts carry visual information from the retina to the

lateral geniculates.

Damage to the preoptic area of the hypothalamus leads to which problem?

reduced ability to regulate body temperature

The mesencephalon contains the headquarters of the ________, a specialized component of the reticular formation that controls alertness and attention.

reticular activating system
