Exam Questions and CORRECT Answers
What makes up the nervous system? - CORRECT ANSWER - The brain and spinal cord
What space surrounds the brain and spinal cord, is filled with cerebrospinal fluid and provides
cushion, nourishes the CNS and removes waste materials? - CORRECT ANSWER -
Subarachnoid space
What is the subarachniod space and what does it do? ( 3 things) - CORRECT ANSWER -
It surrounds the brain and spinal cord and is filled with cerebrospinal fluid which is formed in the
ventricles or the brain and flows through the ventricle into the space
-provides cushion
-nourishes the CNS
-removes waste materials
Name the four divisions of the brain - CORRECT ANSWER - Cerebrum
Diencephalon
Brain stem
Cerebellum
What is the cerebrum composed of? - CORRECT ANSWER - the right and left cerebral
hemispheres
the corpus callosum
What are the four lobes of the cerebral hemispheres? - CORRECT ANSWER - Parietal
Frontal
Occipital
Temporal
,This bundle of nerve fibers is responsible for communication between cerebral hemispheres -
CORRECT ANSWER - Corpus Callosum
What does gray matter in the cerebral lobes do? - CORRECT ANSWER - Mediates
higher-level functions such as:
-Memory
-Perception
-Communication
-Initiation of voluntary movements
Where is the diencephalon located? - CORRECT ANSWER - Beneath the cerebral
hemispheres
The diencephalon consists of? (2 things) - CORRECT ANSWER - The hypothalamus and
thalamus
The thalamus is responsible for what? - CORRECT ANSWER - Screening and directing
impulses to specific areas in the cerebral cortex
The hypothalamus regulates what body functions? (6) - CORRECT ANSWER - -water
balance
-appetite
-vital signs( BP, Respiratory rate,Temp,Pulse)
-sleep cycles
-pain perception
-emotional status
Where is the brain stem located? - CORRECT ANSWER - Between the cerebral cortex
and the spinal cord
, Name the 3 parts of the brain stem - CORRECT ANSWER - -Midbrain
-Pons
-Medulla Oblongata
This serves as a relay system for ear and eye reflexes and relays impulses between the higher
cerebral centers and the lower pons, medulla,cerebellum and spinal cord - CORRECT
ANSWER - The Midbrain
What does the pons "link"? - CORRECT ANSWER - The cerebellum to the cerebrum and
the midbrain to the medulla
This is located in the brain stem and responsible for various reflex actions - CORRECT
ANSWER - The pons
The medulla oblongata contains what? (2 things) - CORRECT ANSWER - -Nuclei for the
cranial nerves
-Centers that control and regulate respiratory function, heart rate and force, and blood pressure
Where is the cerebellum located? - CORRECT ANSWER - Behind the brain stem and
under the cerebrum
What are the primary functions of the cerebellum? (3) - CORRECT ANSWER - 1.)
Coordination and smoothing of voluntary movements
2.) maintenance of equilibrium
3.) maintenance of muscle tone
Where is the spinal cord located? - CORRECT ANSWER - In the vertebral canal and
extends from the medulla oblongata to the first lumbar vertebra
