Radiographic Pathology ch. 8-9
Central nervous system CNS correct answers composed of the brain and spinal cord
Peripheral nervous system PNS correct answers composed of 31 spinal nerves, 12
cranial nerves, autonomic nerves and ganglia
Somatic nervous system correct answers supplies the striated skeletal muscles
Autonomic nervous system correct answers controls the smooth muscle, cardiac
muscle, and glandular epithelial tissue
Neuron correct answers is the basic unit of the nervous system
myelin sheath correct answers a fatty insulation covering the axon which increases the
rate of transmission of nervous impluses
Cerebrum correct answers the largest part of the brain responsible for receiving
sensory information
Brain stem correct answers composed of the midbrain, pons and the medulla oblongata
which lies between the cerebrum and spinal cord
Basal ganglia correct answers islands of gray matter deep within the white matter of the
cerebrum which consist of caudate nuclei, the globus pallidus and the putamen
Diencephalon correct answers consists of the thalamus, pineal body and
hypothalamus. lies between the mid-brain and the cerebrum
Thalamus correct answers relay station that receives sensory impulses before sending
them to the cerebral cortex
Cerebellum correct answers coordinates skeletal muscles to maintain equilibrium and
balance
Meninges correct answers the protective coverings of the CNS is composed of three
layers pia matter (innermost) , arachnoid membrane (middle) and dura mater
(outermost).
Dura mater correct answers tough outermost covering of the CNS
Falx cerebri correct answers is an extension of the dura mater that projects downward
into the longitudinal fissure to separate the cerebral hemispheres
, Tentorium cerebelli correct answers tentlike covering that separates the cerebellum
from the occipital lobe of the cerebrum
Cerebral spinal fluid CSF correct answers fluid that fills the ventricles of the brain to
cushion the brain
Choroid plexus correct answers network of capillaries in the ventricles that form CFS
Arachnoid villi correct answers absorbs CFS into venous blood
Meningitis correct answers acute inflammation of the pia mater and arachnoid
Encephalitis correct answers viral infection of the brain most commonly caused by
herpes simplex is an often fatal fulminant process
Brain abcess correct answers are usually a result of chronic infections of sinuses,
middle ear or mastoids or systemic infections (pneumonia)
Subdural empyema correct answers suppurative process in between the dura and the
outer surface of the arachnoid most commonly caused by the spread of infection from
the frontal or ethmoid sinuses.
Glioma correct answers Most common primary malignant tumor
Oglodendrocytoma correct answers type of glioma that are slow growing and tend to
calcify
Astrocytoma correct answers most common type of glioma slow growing tumor that can
cause large cavities or pseudocysts
Medulloblastoma correct answers rapid growing glioma occur most commonly in
children
Ependymoma correct answers a glioma most commonly arise from the walls of the
forth ventricle in children and the lateral ventricles in adults
Meningioma correct answers benign CNS tumor arises from arachnoid cells and is
attached to the dura
Acoustic neuroma correct answers slow growing benign tumor that occurs on the eight
cranial nerve (auditory nerve)
Chordoma correct answers tumors that arise from remnants of the notochord
(embryonic neural tube), these tumor are invasive but do not metastasize
