Chapter 14 Brain

Damage to the premotor cortex of the frontal lobe would interfere with the ability to

play piano

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

pons

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 the

arbor vitae

The cerebellum can be permanently damaged by stroke or temporarily affected by drugs or alcohol. The resulting disturbance in motor control is known as

ataxia.

Hydrocephalus, or "water on the brain," may result from

blockage of CSF circulation or excessive CSF production.

Nerve fiber bundles on the ventrolateral surface of the mesencephalon are the

cerebral peduncles.

A neural cortex is found on the surface of the

cerebrum

The general interpretive area

allows us to interpret what is read or heard.

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.

The only sensation that is received directly by the cerebrum is

olfaction.

Sensory information is processed and relayed to the cerebrum by the

thalamus

Damage to the medulla oblongata can result in death because

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

Damage to the corpora quadrigemina would interfere with

visual and auditory reflex movements of the head and neck.

The choroid plexus is composed of

BV

________ is a condition resulting from an inflammation of a facial nerve.

Bell's palsy

The elevated ridges of the cerebrum are called

gyri

The sense of taste projects to the gustatory cortex located in the ________ and ________.

insula; frontal lobe

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

hypothalamus

Parkinson's disease is the result of

inadequate production of dopamine by substantia nigra neurons.

The folds of the surface of the cerebrum

increase the surface area of the cerebrum.

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.

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

medulla oblongata

Which of the following is a function of the hypothalamus?

regulates body temperature secretes oxytocin produces ADH controls autonomic centers

The thin partition that separates the first and second ventricles is the

septum pellucidum.

The cerebrospinal fluid (CSF) circulates within the __________.

subarachnoid space

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

substantia nigra
