Chapter 13 Practice Quiz Flashcards
Which of the following is NOT TRUE?
The cerebellum is anterior to the 4th ventricle
There are four ventricles of the brain consisting of fluid that flows from one ventricle to the other. Which of the following correctly describes the flow of fluid from one ventricle to the next?
fluid in the lateral ventricles flow through the interventricular foramen to the third ventricle, then through the cerebral aqueduct to the fourth ventricle, then in and around the spinal cord
Regulation of body temperature is the function of the thalamus.
False
Control of temperature, endocrine activity, water balance, and thirst are functions associated with the:
hypothalamus
Cerebrospinal fluid is produced by the __________.
ependymal cells of the choroid plexus
Medulla oblongata
Cardiovascular center
Pre central gyrus of the frontal lobe
Primary motor cortex
Prefrontal cortex
Complex cognitive behavior, planning, judgement
Postcentral gyrus of parietal lobe
Primary somatosensory cortex
Occipital lobe
Visual cortex
Temporal lobe
Auditory cortex
Insular lobe
Interpretation of taste
Choose the correct statement
in the nervous system the strength of the stimulus is determined by the frequency of action potential
Medulla oblongata
Respiratory center
Substantia nigra
Dopamine production
Thalamus
Receives sensory input and directs it to centers of the cerebral cortex
Broca’s area
Motor speech area
Wernicke’s area
Language comprehension
Hypothalamus
Controls water intake
Red nucleus of midbrain
Control of erector spinal group muscles
Occipital cerebral cortex
Visual center
Reticular formation
Controls level of consciousness
Cerebellum
Balance and coordination
Mr. Right was in a horrific snowmobile accident. Afterwards he had a loss of balance. Which major brain region was probably damaged?
Cerebellum
Which one of the following represents the correct sequence from outermost to innermost layers of the meninges:
dura mater, arachnoid mater, pia mater
The three major parts of the brain stem are the:
midbrain, pons, and medulla oblongata
decussation of pyramids is the crossing of nerve fibers of the motor tract at the ventral/anterior side on the lower portion of the medulla oblongata.
True
Corpus callosum facilitates communication between right and left hemispheres
True
Choose false statement about flow and production of cerebrospinal fluid
Cerebrospinal fluid flows from the lateral venricles into subarachnoid space and then in III and IV venricles.
The cerebrospinal fluid serves several functions. One of the functions is to pick up waste products from the CNS. The CSF then transports the waste to the venous system so the body can ultimately get rid of the waste. How does the CSF transport waste to the venous system?
through the arachnoid villi
Voluntary movement of the right hand is caused by neural activity in the
Left precentral gyrus
Collections of neurons cell bodies inside the CNS are called:
nucleus
Which of the following is NOT TRUE?
The medulla oblongata is superior to the pons
The pineal gland produces melanin, which helps maintain circadian rhythm.
False
Which of the following is not correctly matched with its function?
precentral gyrus of the frontal lobe- somatosensory cortex
Which of the following is NOT TRUE?
Each cerebral hemisphere has a thin outer surface layer composed of myelinated axons
Which of the following is not true?
the periosteal dura mater is deep to the meningeal dura mater
Which of the following is not found in the brain stem?
lateral ventricles
Mr. Smith suffered a stroke. He is able to understand verbal and written language, but when he tries to speak, his words are garbled. What cortical region did the stroke damage?
Broca’s area
All of the following are functions of hypothalamus , except one .
involuntary control of the respiration rate
The meninges cover the __________.
The brain and the spinal cord
Choose the correct statement about cerebrospinal fluid
is continually formed mostly by the choroid plexuses
