Health Assessment Final UTMBWhat 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

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
Name the two pairs of columns of the spinal cord - correct answer-The dorsal and ventral
Name 3 things the spinal cord is responsible for - correct answer-1.) Conducts sensory
impulses up ascending tracts to the brain
2.) Conducts motor impulses down descending tracts to neurons that stimulate glands and
muscles throughout the body
3.) Simple reflex activity
